Abstract

In this paper, the technical method of cooling quench medium with air-cooler in the process of bearing quenching is introduced. The exhausted hot air is directly used to dry bearing balls. It is a novel approach for full utilization of heat energy during heat treatment, which increased 30 % of the heat efficiency when compared with normal air-cooler methods that directly put exhaust air into atmosphere.
