The cooling methods of vacuum heat treatment furnace can be divided into gas cooling, oil cooling and water cooling
There are two kinds of gas cooling, one is heating and cooling in the same chamber, the other is heating and cooling chamber separate
Gas-cooled media are hydrogen, helium and argon, etc., commonly used is 99.999% or more of high-purity nitrogen, easy to be nitriding titanium alloy with hydrogen cooling
Special low steam pressure vacuum quenching oil must be used for oil cooling.
In the case of water cooling, vacuum valves are used to separate the cooling and heating Chambers.
