In materials science, quenching is the rapid cooling of a workpiece in water, oil, or air to obtain certain material properties. For oil quenching furnace, it contents the process of heating and quenching. For casting grinding balls, quenching process can be oil quenching for common high chrome balls, air quenching for super high chrome alloyed grinding balls; and for […]
