Put the workpiece in the inductor made of hollow copper tube, and after passing the intermediate frequency or high frequency alternating current, an induced current of the same frequency is formed on the surface of the workpiece, and the surface or part of the part is rapidly heated (the temperature can be heated up in a few seconds). 800 ~ 1000 ℃, the heart is still close to room temperature) after a few seconds, spray (immersion) water cooling (or spray immersion oil cooling) immediately to complete the immersion work, so that the surface or part of the workpiece can meet the corresponding hardness requirements.
