Heatmasters Temperature Control Systems

For more than three decades, Heatmasters has been at the forefront of temperature control systems for metal heat treatment applications. Industry veterans are already familiar with our legendary Rigel controller and HM20/HM25 temperature control program. This technology has proven to be excellent in both accuracy and ease of use, whilst also offering multiple innovative features for end-users.

AP-Tela

AP-Tela Oy, a Kokkola-based subsidiary of Plc Uutechnic Group Oyj (ex-Vaahto Group), is a provider of heavy custom engineering and contract manufacturing services. The company specializes in the manufacturing of long, welded, and machined axially symmetrical parts. Most of the company’s customers are engineering companies and equipment manufacturers in Finland, Scandinavia, and Russia. Some of their main products include:

  • Heavy, welded, thick-walled steel pipes, cylinders, and cones
  • Rolls for the paper, energy, and lifting equipment industries
  • Welded and machined steel structures

The annealing furnace at AP-Tela’s facilities has dimensions of 2,5 x 2,6 x 12 meters with 450kW heating power. The furnace is in good condition, however, the furnace temperature control system was aged and no longer intuitive or user-friendly. Only a few select employees at AP-Tela had sufficient training to use it properly. The old furnace temperature control system was no longer supported by the manufacturer and there were difficulties in sourcing critical spare parts.

This meant upgrading the furnace temperature control system was important to ensure no downtime and to avoid future maintenance issues.

The customer was already familiar with our Rigel controller and contacted us regarding their need for a modern temperature control system for an existing furnace. Our team of wizards was happy to help and the upgrade project advanced rapidly, with installations being completed 3 weeks after the initial inquiry had been received.

Heat Treatment Works at the Kymijärvi III Bio-Heating Plant Located in the European Green Capital 2021

September 28, 2020

Heatmasters’ heat treatment operators were on site at the Kymijärvi III bio-heating plant prior to its commissioning during 2019. Now, they were back on site for on-site heat treatment works during a project involving the installation of additional piping. The Kymijärvi III bio-heating plant uses certified sustainable woody biomass as fuel, providing Finland’s most environmentally friendly district heating to the city of Lahti.

Lahti – European Green Capital 2021

Lahti has been chosen as the European Green Capital 2021, a title awarded by the European Commission for merits in pioneering environmental actions, innovations and solutions to environmental challenges, and setting an example for other cities. The city has shared a vision of a bold green city with multiple goals such as:

  • Become a carbon-neutral city by 2025, ten years before the rest of Finland
  • Cut down greenhouse gas emissions by 80% compared to the levels in 1990 by 2025
  • Become a zero-waste circular economy city by 2050
  • Protect the nature and valuable surface and groundwater areas
  • Encourage the use of sustainable modes of transport such as walking, cycling, skiing, and public transport

Kymijärvi III Bio-Heating Plant

One larger step towards these goals was taken through the Kymijärvi III bio-heating project, started in 2014 by Lahti Energia, the local district heating company. The Kymijärvi III 190-megawatt bio-heating plant has now replaced the coal-fired Kymijärvi I plant which was started up in the 1970s, reducing Lahti Energia’s carbon dioxide (CO2) emissions by approximately 600 000 tonnes per year.

The plants CFB (circulating fluidized bed) energy-efficient multi-fuel boiler enables the use of multiple solid fuels in addition to certified biomass, which secures the plant’s operations in the future which may bring changes in energy policy and markets. Currently, the plant has a district heating capacity of 190 megawatts, with equipment in place to also enable electricity generation in the future. The plant utilizes innovative technologies to ensure all process waste is recycled and no sulfates end up in water bodies.

Heatmasters Heat Treatment Services

Heatmasters has decades of experience in heat treatment works across many industries, including the heat treatment of CFB boiler components and on-site heat treatment works within energy industry facilities.

Our wizards of metal were working at the site for approximately 18 months prior to the plants commissioning, providing a wide range of heat treatment services. Now, our operators were on-site again to provide heat treatment services during additional piping work, which was executed to ensure smooth and reliable heat production in all operational conditions at the Kymijärvi III bio-heating plant.

Several of our operators equipped with 4 six-channel 40kVA heat treatment units completed pre-heating and post-weld heat treatment (PWHT) works at the plant, located right next door to the Heatmasters headquarters. The Heatmasters HM406T heat treatment unit and our experienced team of wizards ensured that heat treatment was well documented and met the highest quality standards.

Heatmasters Pre-Heating @ Kymijärvi II (2019)

The HM406T is a fully automatic heat treatment unit designed for preheating and annealing metal workpieces. The unit features our state-of-the-art temperature control system which means that setting, controlling, monitoring, and documentation of heat treatment parameters are carried out quickly and accurately. Heatmasters heat treatment units are also relatively portable, weighing only half of the weight of traditional units, and being small enough to move around by hand, even through doorways, etc. which is an important factor to consider for on-site heat treatment works such as during this project.

Continuous Improvement Process of Solution Annealing Heat Treatment

July 30, 2020

SHI FW Energia FAKOP Sp. z o.o., a subsidiary of Sumitomo SHI FW and Heatmasters Poland once again carried out a joint-defined solution annealing heat treatment process for high alloyed stainless steel coil assemblies. Despite our long-lasting practices and procedures, the details of this process have again been improved thanks to evolving industry drivers and the existence of continuous improvement practices in both companies. In-depth knowledge, experience, team-work and focus on details have allowed us to take another step toward superior quality and longer product lifetime, resulting in decreased maintenance downtime for the end-users.

Heatmasters Poland has provided solution annealing for these parts multiple times during the past five years, working with SHI FW Energia FAKOP’s Quality Specialists to further optimize and perfect our unique annealing processes. By continuously reviewing every single detail during the entire solution annealing process, from transportation and storage to thermocouple placement, we are working together with SHI FW Energia FAKOP to continue delivering the highest-quality components to end-users across the globe.

This time, the parts were loaded into our U117 heat treatment furnace. This furnace has dimensions of 4,4 x 2,4 x 1,2 meters and uses a fork loading system. The hat of this furnace was recently refurbished with improved insulation material to increase energy efficiency.

The parts were heated to a temperature far above 1000°C and Heatmasters Rigel26 digital temperature control system ensured an accurate and well-documented heating process. After heating, quenching took place within the targeted time period to form the desired microstructure in the material. Usually, water cooling would be a great solution, but in this case, it would change the shape of the elements too much, resulting in additional fabrication effort and additional stress into assemblies. Fast air cooling was a suitable approach as it allowed us to avoid negative material structures but still hold the shape of the elements. A total of 68 elements were processed this time.

A total of 68 components were treated in our U117 heat treatment furnace.

Heatmasters Service Combo: Pre-Heating and PWHT Of Boiler Drums

July 23, 2020

Last month, we wrote about our cooperation with ENITEC Sp. z o.o. (Grupa ENERGOINSTAL S.A.), manufacturer of boiler components and pressure vessels for the energy industry at the highest quality levels. Heatmasters provided a service combo for Enitec, which included pre-heating and PWHT (post-weld heat treatment) of a boiler drum. These service combos are a part of our integrated service model which provides our customers with multiple benefits arising from complete solutions.

“Despite the challenges of this job, such as large dimensions and weight, the materials involved, the requirements of standards and regulations, thanks to the expert advice provided by Heatmasters and professionalism in pre-heating and post-weld heat treatment, the task was completed successfully.”

– Michał Krawiec, Project Engineer at Enitec Sp. z o.o

On-Site Pre-Heating

Heatmasters’ wizards of metal with decades of heat treatment experience were on-site at Enitec’s facilities in Poręba, southern Poland, providing accurate pre-heating during the supervised process, which in addition to heat treatment involved welding and dehydrogenation.

Pre-heating metals is an additional, but often crucial step in welding applications. Pre-heating metal before welding decreases the temperature difference between the welding arc and the material being worked on. It ensures the rate of cooling in a finished weld is slower, lowers the chance of cracking, and allows hydrogen to diffuse out. It also ensures that any moisture or contaminants on the surface of the part are removed, which could otherwise allow the introduction of hydrogen during the welding process.

There are many factors to consider when preheating in welding is required such as welding code or standard requirements, prior cracking issues, component section thickness, base metal chemistry, ambient temperature, and filler metal hydrogen content. Most often, welding codes or standards will specify the minimum preheat temperature based on the welding process and component material/thickness.

During the pre-heating works, our team used two Heatmasters HM406 pre-heating units. These units had a combined power output of 80 kW and 12 heating channels.

We also utilized our VHY-Stud Heater elements, designed for the pre-and post-weld heating of studs and outlet tubes. The form of the VHY-stud heater enables fixing the heater near the weld.

The pre-heating works went well, and we were glad to be working together with fellow professionals at Enitec’s facilities. The project, however, was far from over as boiler drums would also receive post-weld heat treatment after works at Enitec’s facilities were completed.

PWHT

The boiler drum, weighing 38 tons, was transported to our modern heat treatment facility in Będzin, Poland which is equipped with several fixed heat treatment furnaces. The journey was only around 30km which meant transporting the boiler drum was a feasible and cost-effective solution. In other cases, in which transport would not have been feasible, Heatmasters can provide a temporary furnace solution at the customers’ premises.

The boiler drum was loaded into a furnace with dimensions of 16 x 4 x 4 meters and a maximum temperature of 950°C. The heating process took around 40 hours per drum, during which the heating parameters were controlled and documented using the Heatmasters Rigel26 digital temperature control system. This system ensures that each heating process is performed accurately, according to the customers’ requirements and fabrication codes.

The electrical heat treatment furnace and boiler drum almost ready for heating.

The heating process takes around 40 hours per drum.

Boiler drums are loaded and unloaded using 2 cranes.

Once the heating process was completed, cooling to ambient temperatures took another 18 hours. After this, the boiler drum was transported back to Enitec along with digital heat treatment certificates and other required documentation.

Integrated Service Model

When our customers choose multiple services or complete service solutions, we can manage a selected part of the delivery process. This service model allows for an optimized process, saving time and effort, whilst our customers have fewer moving parts to take care of and fewer jobs to juggle. During this project, we provided the customer with pre-heating and PWHT according to the highest quality and code standards. Additional services such as transportation, NDT, and surface treatment services were also available for the customer.

”We appreciate Heatmasters’ experience in steel heat treatment and recommend them as a proven partner.”

-Krystian Kowal, Vice President at Enitec Sp. z o.o.

Heatmasters team enjoyed this cooperative project and we are already looking forward to future challenges utilizing our knowledge and long-term experience in high-quality heat treatment and industrial services. Our cooperation with Enitec continues with the processing of several additional boiler drums.

Maintenance Services at Olkiluoto Nuclear Power Plant

June 16, 2020

The Olkiluoto Nuclear Power Plant is located on the Olkiluoto Island on the Eura River and it is owned by Teollisuuden Voima Oyj (TVO). The nuclear power plant units Olkiluoto 1 and Olkiluoto 2 (OL1 and OL2) consist of two BWRs (boiling water reactors), each producing 890MW of electricity. OL1 was first connected to Finland’s national grid in September 1978 and OL2 followed in February 1980. Since then, Teollisuuden Voima Oyj (TVO) has systematically modernized the OL1 and OL2 plant units during annual outages and modernization projects to ensure safe and efficient operations, currently planned until 2038. Heatmasters was on-site again during this year’s annual outage, utilizing our heat treatment solutions during the repair of valves in OL1 and OL2.

Annual Outages 2020

This year, the annual outages at the OL1 & OL2 plant units were carried out with some adjustments due to the ongoing COVID-19 pandemic. There were several measures taken to safeguard the health and safety of every individual involved in the annual outages. All larger maintenance works which were not critical in terms of safety or availability were postponed to a later date. However, there were still multiple significant works taking place including reactor refueling. With a total of 730 contractor employees, 4800 work phases were carried out. The total duration of the annual outages was approximately four weeks.

Heatmasters On-Site Heat Treatment

During the project, Heatmasters was working with Recion Oy, a leading industrial service provider carrying out projects throughout Europe and delivering prefabricated products globally with niche expertise in high-pressure piping solutions.

Heatmasters provides custom-tailored heat treatment solutions and industrial services anywhere in the world, with a focus on flexible and cost-efficient solutions that do not compromise on quality. Our operators are specialized in on-site works taking place across a multitude of industries with high-standards and quality requirements. For this project, in addition to their decades of heat treatment experience, our operators required additional background checks and multiple safety certificates related to working at the plant.

Our wizards were already familiar with the work being done as they had prior experience working at the plant units during previous years. The maintenance work went smoothly, even though the current COVID-19 situation added some things to take into consideration. Upon arriving at the site, our heat treatment specialists passed through a disinfection station and were given personal protective equipment such as masks. They also received detailed instructions in advance from TVO’s annual outage coronavirus group at the site.

During the first week, our team transported equipment to the site in OL2 and prepared everything for heat treatment. Transporting equipment to the site is always a complex process within facilities such as nuclear power plants due to strict safety measures and reporting. Our heat treatment operators utilized our HM406T transformer with several resistive heating mats during this project.

The HM406T2 is a semi-automatic preheating unit, suitable for on-site preheating of metal parts. These thyristor-controlled transformer units have been designed with usability in mind, their simple and lightweight structure allows effortless mobility and efficient pre-heating at any location. Along with our experienced operators, it was the perfect solution for this project which required moving around on-site.

Due to the location of the job, there were further restrictions regarding loose equipment & tools. This meant we could not attach heating mats to parts being treated with clips and bands as is usually done. Our heat treatment specialists on-site had a creative solution and used thermocouple wire to attach the heating elements to the valves which were being pre-heated.

“This year, annual outages were completed successfully despite exceptional circumstances.” – TVO

After the first week, pre-heating had gone well, and one valve was repaired in OL2 and our team moved to the other plant unit. At OL1, two valves would be pre-heated & repaired. Moving equipment from one plant unit to the other did not take as long since it was already at the plant area, which was taken into consideration during planning and we had two valves that required pre-heating at OL1.

Of course, all heat treatment processes were digitally documented, and the process was done in accordance with our extensive quality management system, ensuring the highest level of customer service and quality. The work phases were completed successfully and the annual outages of 2020 were completed as the Olkiluoto 1 plant unit (OL1) was once again connected to the national grid and electricity production on the 8th of June, 2020.

Furnace Modernization: From Gas to Electric

April 23, 2020

Heatmasters provided Alu-Releco with a furnace modernization solution which allowed them to move from an old gas-burner furnace to a modern electric furnace. Like all of our solutions, it was custom-tailored to meet their needs whilst providing all the benefits of a modern furnace and temperature control system.

Alu-Releco has decades of know-how and experience with surface treatment & coating processes, specializing in professional surface treatment with Teflon- and fluoroplastic coatings. Alu-Releco coating solutions are used across all industries, which means their processes and equipment need to meet the expectations of their clients and rigorous quality standards. Their surface treatment facility in Riihimäki, Finland utilized a furnace with gas-burners to heat metal parts. Heating was done to ensure that there were no contaminants such as dirt and grease prior to the application of the surface coating. The size of the furnace is 5*2,5*2,5m with a maximum operating temperature of 500°C.

What Was the Issue?

Alu-Releco shared their concerns related to this furnace with our team of heat treatment specialists. The furnace was unreliable and had issues with temperature uniformity. The fact that the furnace was fueled by gas was also an issue as it requires additional permits. And this furnace was quite old, which meant it lacked the energy efficiency of modern furnaces and cladding was in poor condition. The temperature control system was also outdated.

The old furnace was in poor condition prior to the modernization.

Furnace Modernization

After discussing and mapping the needs of Alu-Releco and careful analysis of the old gas-burner furnaces condition, Heatmasters decided that the best route of action was to modernize the furnace into a modern electric furnace with convection heating. This modernization was done locally, at the Alu-Releco surface treatment facility in Riihimäki, Finland.

The modernization process was completed by our heat treatment specialists at the customer’s facilities.

The modernization process was completed by our heat treatment specialists at the customer’s facilities.

During the furnace modernization process, all gas-burners and related equipment were removed as the new furnace would no longer be fueled by gas. The rest of the furnace was dismantled down to its frame and new insulation and cladding were installed to ensure optimal energy efficiency. Electric heating elements were installed along with convection blowers to ensure even heat distribution during the heating process. Naturally, all electrical systems and electric cabins were also installed to meet today’s standards.

Heat Treatment in Poland – Celebrating 25 Years

February 25, 2020

The Beginning of Heat Treatment in Poland

Heatmasters in Poland – it all began back in 1995, when the metal workshop of A. Ahlström Oy (a Finnish pulp & paper manufacturer), asked Heatmasters’ (Lahden Lämpökäsittely Oy or Lahti Heat Treatment Ltd in English at that time) willingness to provide heat treatment services at the Ahlstrom Fakop Sp. z o.o.. workshop. This workshop was situated in southern Poland, in the town of Sosnowiec and it was mostly run by Finnish employees. This would be the beginning of heat treatment in Poland.

The management of Heatmasters analyzed the situation and made an offer for heat treatment services, which was then accepted in the form of a letter of intent. Cooperation with the former employees of the Fakop maintenance unit was started. The company was acquired by Heatmasters and Remo-Ster Sp. z o.o.. The company was renamed to Heatmasters Sp. z o.o..

Preparations began immediately and supplies and heat treatment equipment were delivered to Sosnowiec, Poland. At the same time, one bold, only Finnish-speaking heat-treatment specialist left Finland to oversee the construction of the furnaces, the commissioning of other equipment, and training. Another employee of Heatmasters took over the responsibility for activating the business operations within Poland soon after.

The company recruited two heat treatment trainees, one of whom is still employed by the company after 25 years. Operations began with practical training and construction of heat treatment furnaces in the premises leased from the Fakop factory.

In 1996, Fakop was acquired by the American company Foster Wheeler and the new partner was renamed Foster Wheeler Fakop. The building of customer relationships started from square one in May of 1996, as the last Finn left the Fakop factory.

First Steps

For almost the entire first year of operation, the company used an office space of approximately 18 m² inside a site container. The container later remained as a heat treatment facility when the offices moved to a two-room space near the furnaces. The responsibilities of Finnish Heatmasters as a trainer and participant in practical work ended in December 1996. The company’s operational activities were taken over by the local CEO. Operations continued with a focus on the furnace and local heat treatment services, with the main customer being Foster Wheeler Fakop.

Time for Change

In 2001, Foster Wheeler Fakop announced a change of premises. The facilities used by Heatmasters were demolished. However, the company was assigned a new space for operations outside the plant site right away. The same thing happened again a few years later. The transfer operations required constant flexibility from the company as the largest furnace which had to be moved was 3.5 x 20 m.

In the mid-2000s, the board of directors of Heatmasters was informed of a building being auctioned in the immediate vicinity of the factory. The building was offered at a minimal price and ownership was transferred to the company.

10-Year Anniversary

By 2005, the company had grown from two heat treatment specialists to 15 heat treatment specialists as heat treatment projects continued to come in. Finnish Heatmasters made a trip with Polish colleagues to celebrate the 10th anniversary of Heatmasters Poland. Celebrations happened in the Tatra Mountains with activities such as horseback riding.

Expansion of Heat Treatment Operations in Poland

Business operations continued to be busy and in 2006, the company built the first gas furnace. The customer base expanded and in 2010 the company signed an agreement with Stama Sp. z o.o., to start furnace operations at their factory. A 1.4 MW furnace with a floor area of 20.0 x 5.8 m was built at Stama’s premises.

In 2010, as Foster Wheeler Fakop expanded its operations, space became an issue and the search for new facilities/premises began. The new facilities were found about 2 kilometers away, from the town of Będzin. The remodeling of the new premises was completed in 2012.

Modern Facilities

In 2018, facilities were moved once again within Będzin. The new, modern facilities were within the same industrial area, but allowed us to better serve customers with not only heat treatment but also blasting and painting. Operations in Będzin continue, and the future looks bright!

HM406T2 – A 40 kVA Fully Automatic, Six-Channel Heat Treatment Unit

January 17, 2020

The HM406T2 is a 40 kVA fully-automatic, six-channel heat treatment unit for preheating and annealing metal workpieces. We are ensuring our clients receive innovative equipment, designed with industry requirements such as ease-of-use and a long product lifetime in mind!

The setting, controlling, monitoring, and documentation of heat treatment parameters are carried out by Heatmasters’ computerized state-of-the-art control system.

All channels can be independently programmed. 12 heating elements can be connected, two per channel.

HM406T2 will carry out the programmed heat treatment process according to the given parameters. The process can be monitored from the controller, or managed using a laptop (even remotely with a GSM data line). This means heating can be started at any time, even remotely.

The controller registers the achieved heat treatment results in its memory, which enables easy preparation of heat treatment documents. A separate temperature recorder is not needed.

Thanks to its signal light system, the operating status of the heat treatment unit is always known and possible disturbances in the electrical network or heating resistors are noticed right away by the operator.

The stainless steel body gives the unit a sleek look and a long lifetime!

The unit uses thyristors in power output control, minimizing maintenance work and resulting equipment downtime.

It is also relatively portable, weighing only half of the weight of traditional heat treatment units, and being small enough to move around by hand, even through doorways, etc. Designed for on-site heating works, this unit is popular among our customers and our own wizards – working in facilities such as nuclear power plants or chemical plants, where equipment mobility is an important factor.

Our product range covers the market’s most advanced heat treatment units for pre-heating and PWHT of metal objects. This includes semi- and fully-automatic units available in 3 or 6 channel variants with heating power up to 50kVA.

We also offer portable inverter-based units.
