Such a vacuum gas quenching furnace -99% of people do not know

Vacuum gas quenching furnace is a vacuum heat treatment furnace which USES inert gas as cooling medium to quench the workpiece after heating. Common classifications of vacuum gas quenching furnace are:


According to the different air cooling pressure is divided into:


Negative pressure air cooling (<1 105Pa), pressurized air cooling [(1 ~ 4) 105Pa], high-pressure air cooling [(5~10) 105Pa] and ultra-high pressure air cooling [(10 ~ 20) 105Pa)], the increase in pressure is conducive to improve its cooling speed, to adapt to the cooling requirements of different steel types.


According to different air cooling modes, it can be divided into:


Gas cooling mode of vacuum gas quenching furnace is divided into inner circulation and outer circulation. The fans and heat exchangers in the inner circulation mode are installed in the furnace shell, while the fans and heat exchangers in the outer circulation are installed outside the furnace body, which is separated and installed with the furnace body. The gas is cooled through the external circulation.


Vacuum gas quenching furnace is also divided into:


There are three types of horizontal type furnace, vertical type furnace and semi-continuous type furnace. Horizontal type furnace and vertical type furnace can be divided into two types: single chamber and double chamber. The semi-continuous furnace has three Chambers: the preparation chamber, the heating chamber and the cooling chamber.
