  • Ultrasound-assisting quenching process and device for performing the same
    Patent number: 10273550
    Abstract: An ultrasound-assisting quenching process includes: S1) connect the workpiece with the ultrasonic unit tightly; S2) heat the workpiece to the quenching temperature and then hold for a period of time; S3) start the ultrasonic unit, then the ultrasound energy can be injected into the workpiece directly; and S4) put the workpiece into the coolant quickly to make the workpiece to be quenched. The device for this process mainly includes the ultrasonic unit and a heating unit. This invention inputs the ultrasound energy into the workpiece during the quenching process. Under the action of the ultrasound, the grain size of the workpiece after quenching process will be much smaller compared with the conventional quenching process. Therefore, the ultrasound-assisting quenching process can improve the strength and plasticity of the material, and extend the life of the workpiece.
