The vacuum double-chamber oil quenching furnace has the function of vacuum heating and oil quenching, with the option of 2 bar air cooling, providing more process selection methods and processing applications range. Widely applicable to vacuum heat treatment of precision parts of high, medium and low alloy steels.
It’s mainly for the quenching of low-alloy steel, carbon steel, or big size alloy steel.
It has bigger cooling rate than air quenching.
