As a result of its unique properties, aluminum has been of key importance in many of the developments of the past century. Let’s look at that history and some great nonferrous products/applications along with their thermal treatments.
Why is aluminum’s story only about a century old? Because although aluminum is the most abundant metallic element in the earth’s crust (8%), metallic aluminum was produced for the first time just 200 years ago.
Tenova LOI Thermprocess received an order from Russian’s JSC Pervouralsk Pipe Plant for a roller-hearth continuous furnace system for bright annealing stainless steel pipes in a 100% hydrogen atmosphere. The heat-treatment system is designed as a roller-hearth furnace for the bright annealing of 2,000 kg/hour of austenitic stainless steel and nickel-based alloy pipes. The solution annealing of these high-alloy steel grades is carried out in the temperature range of 2012-2192°F (1100-1200°C). The tubes are heat treated in this continuously operating system using a 100% hydrogen atmosphere as process gas.
Abbott Furnace Company received an order for a sintering furnace from a company that specializes in manufacturing ferrous-based, powder-metal components for the automotive, agricultural and industrial markets. The electrically heated, continuous-belt furnace, which is rated at 2150°F, will be delivered in the second quarter of 2020. Abbott Furnace will design, manufacture and install the furnace, which includes the Varicool cooling system. This will be the 36th furnace Abbott Furnace has supplied to this company.
Lindberg/MPH shipped an electrically heated pit furnace to a manufacturer in the power industry. The furnace is designed with a maximum operating temperature of 1750°F and gross workload of 1,600 pounds. It can accommodate a work basket 25 inches in diameter and 48 inches deep. A retort minimizes atmosphere consumption and furnace conditioning time between loads. The cover lid utilizes an electrically operated boom lift, which provides ease of loading and unloading. An upper furnace fence guard was also installed to provide added safety.
After 32 years at the helm of INEX Inc., a Holland, N.Y.-based provider of silicon-carbide radiant tubes, owner Mike Kasprzyk announced his retirement. Kasprzyk will continue to be active in the company by supporting Michael Rumfola, new owner and president. Rumfola brings 25 years of experience in the heat-transfer industry to INEX. He has a bachelor’s in physics from Fredonia State University and a bachelor’s in mechanical engineering from the University of Buffalo. Kasprzyk, meanwhile, will also serve as a consultant.
IHEA’s Fundamentals of Industrial Process Heating online learning course is scheduled to begin April 13, 2020. Students benefit from the flexible online format that includes interactive forums with other students and scheduled office hours with the instructor. It’s an affordable alternative to campus-based classes and allows students to go at their own pace.
L&L Special Furnace Co. Inc. shipped five box furnaces to a manufacturer of chemicals and chemical coating products located in the Midwest. These products are primarily used in the medical field as a coating and must be cured at 800°F. The furnaces can also be used for sintering of chemical powders up to 2200°F. The furnaces have an effective work zone of 10 inches high x 15 inches wide x 13 inches deep. They are designed to be placed on a benchtop or with an optional furnace stand.
Ipsen USA installed a vacuum furnace at Stack Metallurgical Group’s site in Spokane Valley, Wash. Formerly known as Inland NW Metallurgical Services, Stack Spokane is one of the company’s four locations offering a range of metal-processing services. Installation of the 2-bar vacuum furnace, which will be used to process critical aerospace components, was completed in late 2019. Stack operates four Ipsen furnaces in Spokane and 12 more at its site in Portland, Ore.
Quintus Technologies received an order for a hot isostatic press (HIP) from HT-MX, a heat-treatment specialist based in Chihuahua, Mexico. The press includes Quintus’ proprietary uniform rapid cooling (URC) feature, which combines HIP and heat treatment in a single process. The HIP has a hot zone measuring 14.8 inches (375 mm) in diameter and 47.2 inches (1,200 mm) in height. It operates at a temperature of 2550°F (1400°C) and a pressure of up to 2,070 bar (30,000 psi).
Onejoon Thermal Solutions acquired Eisenmann Thermal Solutions, which specializes in the development, manufacture and sale of industrial furnaces for the production of various materials. Onejoon Thermal Solutions is a subsidiary of Korea’s Onejoon Co. Ltd., which is a mechanical engineering company that specializes in the manufacture of furnaces for processing cathode and anode materials in the lithium-ion battery industry. The transfer of business operations will take place on Jan. 15. Both of Eisenmann’s sites in Germany (Böblingen and Bovenden) and all 200 jobs will be retained. Onejoon Thermal Solutions GmbH will be based in Bovenden.
