The company has developed a process to accurately control the thickness of the quenching layer of the automobile axle piston cover. The large-diameter effective coil of the sensor is first placed on the upper end of the inner hole of the automobile axle piston cover, and the upper end face of the inner hole is quenched to form a hardening layer; Turn over the automobile axle piston cover, select the effective coil of the sensor that matches the diameter of the outer surface of the automobile axle piston cover, and quench the other end face of the hole. The quenched side is immersed in the quenching liquid, so that the heat of the effective coil of the sensor will not be affected. Compared with the prior art, the invention has the advantages of energy saving, high efficiency, easy automation, good working conditions and high heat treatment quality. Through actual production and inspection, it is proved that the quenching process of the invention can ensure the quality and hardness requirements of parts.
