Abstract:
     The process employs the active salt bath preheating instead of normalaic preheating or medium bathe preheating, employs the active salt bath tempering instead of normal medium salt bath tempering canbe proceeded at the same time.As compared with onrmal heat treatment technigue, this process can reduce procedures. shorten the period of heat treatments by 2to 3hours, improve the wearing resistance and service life of various strcture steel, die steel, tool steel and strainless steel. This process is widely used in the heat treatment of varios parts such as die, chain, axle, saw, bolt, pin etc.
