Industrial vacuum furnace pressure quenching heat treatment research

A company's latest work in pressure quenching system is to improve the processing capacity of disc type vacuum heat treatment furnace, the company to obtain the high hardness can meet the strict parts as stress strain, the research objective of the fire. The adoption of pressurized gas in the vacuum furnace cooling system, improves the performance of the process and parts to improve, so lead to pressure vessel furnace in the whole industry. Because of the limitation of the furnace under positive pressure operation is very strict, this requires that the operator must strictly abide by rules of operation when using the device. The service life of the furnace due to the performance of the high pressure change, so must be of high pressure gas quenching furnace is often established test and operation procedures.
The pressurized gas quenching process is implemented by adopting high speed circulation gas, in order to achieve a high cooling rate, high velocity gas absolute pressure in l.s xlo5Pa. The low pressure quenching eliminates several atmospheric pressure under the strain of fire restrictions, reduces the vacuum container manufacturing costs, and greatly reduce the consumption of gas quenching. The characteristics of engineering design as soon as possible, the feasibility of repair was the pressure to consider the main problem in the design of quenching system. This furnace design feature is to emphasize the most popular and convenient, which in order to maintain and easy to close to the stove hot when charging, furnace furnace chamber is interrupted.
