Abstract: The bearing ring made of SAE5120, after carburizing and quenching, the deformation of the ring is bad.The deformation of the bearing ring can be effectively controlled through induction heating and die quenching. The application of different pressures and heating processes on the mold has a significant impact on the deformation and physicochemical properties of the ring. This article elaborates on different mold pressing quenching methods and,through statistical analysis, obtains the effects of mold pressure and quenching medium concentration on deformation and grinding allowance.
