Today’s News from Abroad installment highlights more carbon-cutting trends from the steel industry, ranging from robots in the cast house to recycling best practices.  

Heat Treat Today partners with two international publications to deliver the latest news, tech tips, and cutting-edge articles that will serve our audience — manufacturers with in-house heat treat. heat processing, a Vulkan-Verlag GmbH publication, serves mostly the European and Asian heat treat markets, and Furnaces International, a Quartz Business Media publication, primarily serves the English-speaking globe. 

Robots Bring Safety to Casting

“Thai steel producer Siam Yamato Steel has implemented a new robot concept from Primetals Technologies, including LiquiRob, at its steelworks in Map Ta Phut . . .. Thanks to the robotics solution, safety and occupational health in the steelworks have significantly improved. Previously, workers who manually operated the shadow tube had to stand directly next to the distributor and the stream of steel flowing out of the ladle. In the case of a so-called ‘frozen pan.’”

“SSAB’s Board of Directors have taken the decision to proceed with the next step in SSABs transition, building a state-of-the-art fossil-free mini-mill in Luleå, Sweden. When completed SSAB will close the current blast furnace-based production system. This will reduce Sweden’s CO2 emissions with 7% in addition to the 3% from the Oxelösund mill conversion.”

Vacuum Induction Melting Solution from Upper NY

/ AEROSPACE HEAT TREAT, AEROSPACE HEAT TREAT NEWS, AUTOMOTIVE HEAT TREAT, AUTOMOTIVE HEAT TREAT NEWS, ENERGY HEAT TREAT, ENERGY HEAT TREAT NEWS, FOUNDRY CASTING, FOUNDRY CASTING NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS

A custom-built vacuum induction melting (VIM) equipment is set to expand thermal processing for a manufacturer, whose operations already has two VIM solutions. 

The furnace will be fabricated at the Buffalo headquarters of Retech, a SECO/WARWICK Group subsidiary, to capitalize on available schedule improvements. As custom equipment, the subsidiary’s furnaces are not dependent on assembly-line style construction, so they can be fabricated and assembled just in either location.

While this client prefers not to divulge this VIM’s application, Retech’s solution can handle casting a wide range of materials used in applications from automotive and consumer products to critical, high-value equiaxed, directionally solidified, or single-crystal aerospace parts. Almost every furnace Retech makes is modified to meet the specifications and associated applications of its clients.

Manufacturer To Receive EB Furnace for Large-Ingot Casting

/ FOUNDRY CASTING, FOUNDRY CASTING NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS

A North America-based company is set to receive a four-gun electron beam hearth melting furnace from their industry partner of 3 years.

Retech, a division of SECO/WARWICK Group, received this third contract in as many years from the returning partner after the successful planning, installation, commissioning, and subsequent operation and progress of the last two EB hearth melters. Along with that, repeat orders from a known partner reduce uncertainty and risk for the company. Put more simply, practice makes perfect.

These EB furnaces have a throughput that is suitable for large-ingot casting of reactive/refractory metals when alloying with metals having similar vaporization temperatures, whereas plasma arc melting, although slower, would be the more suitable choice for dissimilar vaporization temperatures.

“We are thrilled to be an ongoing partner in this customer’s growth,” said Earl Good, managing director of Retech Systems. “We know they have multiple competitive options for their vacuum metallurgy equipment, so we take nothing for granted, and work hard to earn their business every step of the way. Ongoing awards like this suggest we’re doing a lot of things right.”  

Retech produces and assembles vacuum melting equipment entirely in North America. Their integrated R&D, manufacturing, and assembly facility in Buffalo allows them to do that. The North American supplier also has exclusive use of electron beam guns from Von Ardenne, industry pioneers of electron beam technology.

One of the world’s largest producers of jet engines has modernized their casting furnace, which was last updated two decades ago.

This company has two casting units supplied two decades ago by RETECH, a North America-based company belonging to the SECO/WARWICK Group. The modernization project was for the VIM EQ furnace - a system for the production of castings in equiaxed crystallization. It will involve replacing almost all the furnace components except the power supply, melting chambers and mold. The platforms will also remain unchanged. The remaining components will be replaced with more modern, ergonomic, and user-friendly parts and assemblies.

Says Sławomir Tomaszewski, vacuum melting team director at SECO/WARWICK, “This order includes the complete elimination of hydraulic components by replacing them with electrical components such as an elevator drive or crucible rotation drive. In addition, two old feeders: one for loading crucibles, the other for removing disposable crucibles, will be replaced with a modern system that can perform both activities."

He added, "An additional advantage of the operation will be the fact that the furnace operator will not have to come into physical contact with hot used crucibles, because they will be removed automatically without human intervention."

"For the customer, this means that the availability of large, heavy sheets increases. With these, weld seams can be saved and, thanks to more efficient production, more offshore foundations can ultimately be produced and installed. The modernization of the slab impact furnace, as well as the new edge milling machine for the delivery of “fabricated” offshore wind sheets, is one of a number of investments in the offshore wind market that are currently being planned and implemented at Dillinger."

“Most of the Alfa Laval steel purchased from Outokumpu, a global steel manufacturer, will now be the low carbon stainless steel variety. This change applies to heat exchangers used in the energy transition towards a more sustainable energy supply, including energy efficiency, waste heat recovery, and heat pumps. These heat exchangers are currently produced in large quantities with the potential for future growth, says Alfa Laval.”
