The endothermic generator has been used in heat treating for decades. It was first introduced into the heat-treating market to produce consistency for a nonoxidizing, carbon-rich source for a neutral or carburizing atmosphere.
Lindberg/MPH shipped a four-chamber hot-stamping furnace to the Gestamp Research and Development facility in Auburn Hills, Mich. Gestamp is an international corporation that designs, develops and manufactures metal automotive components. The electrically heated furnace has one stack of three high-heat chambers and one low-heat chamber. The maximum temperature rating of the high-heat chambers is 1922°F (1050°C), and the low heat chamber has a maximum temperature rating of 1004°F (540°C). Each furnace chamber has load space dimensions of 36 inches wide x 30 inches deep x 8 inches high.

What started with one furnace in one plant is now four plants, over 270,000 square feet of space and 64 million pounds of monthly capacity. So is the story of Heat Treating Services Corporation of America (HTS).
Tenova, a company of the Techint Group, concluded the selling process of the HTC Group, which includes IVA Schmetz (Germany), Mahler (Germany), Fours Industriels B.M.I. (France) and IVA Schmetz Industrial Furnaces (China). All four companies specialize in advanced technologies for heat-treatment processes for components. The purchasers are Qizhi GmbH and Shanghai Qizhi Information Technologies Co. Ltd., both members of Ningbo Qijing Holding Co. Ltd.
Solar Atmospheres hosted 28 high-school students enrolled in the Summer Engineering Institute (SEI) at Lehigh University on July 11. The group also included a few members of Lehigh University undergraduate students and staff. The SEI program is a two-week residential program, running two sessions back to back. Students are nominated by faculty of local high schools, and the program specifically targets under-represented groups including girls, first-generation students and students who might otherwise have limited opportunities to study in the fields of science, technology, engineering and math (STEM).
The heat treatment of steel often involves heating a component part into the austenite region (aka austenite phase field) in order to perform a thermal treatment such as normalizing, hardening, case hardening, etc.
