vacuum gas quenching furnace for heat treatment
For many years, high-pressure vacuum gas quenching furnaces have been the process of choice for heat treating high-speed steels as well as hot- and cold-worked tool steels. With the development of self-contained vacuum chambers for high-pressure gas quenching, it is often possible to replace oil quenching with quenching in high-pressure vacuum furnaces using nitrogen or helium for heat treating hardened steels or other low-alloy materials. The success of this dry hardening technology is based on its environmental and commercial effectiveness. Quenching gases such as nitrogen or ammonia are completely inert and do not pose an environmental risk. They do not leave any marks on the workpiece or in the hardening furnace.
Advantages of gas hardening
In vacuum furnaces equipped with quenching chambers, quenching gas streams are supplied at a rate that requires the use of high pressure nitrogen or ammonia gas streams. There is a big advantage here: the cooling gas does not cause metal deformation or change in size. This, by the way, is a feature that cannot be replicated when quenching in liquid. In addition, the process is significantly accelerated, so the hardened workpieces receive a more sensitive cooling profile. High pressure gas cooling systems with perfectly timed quench slots are much easier to control than oil or water quench systems.
