What quenching oil is used in vacuum oil quenching furnace:
When using vacuum quenching oil, the saturated steam pressure of vacuum oil is low, it is not easy to volatilize under vacuum or low pressure, and the cooling capacity can play normally (conventional quenching oil is easy to reduce the cooling capacity due to vacuum or low pressure). Corresponding to bearing steel parts, it is required to have certain cooling capacity, so choose the one with low viscosity and fast cooling speed in vacuum oil.
