หลักการของ high frequency quenching power supply

It mainly works on the principle of electromagnetic induction heating, which refers to the heat treatment method of using high-frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece to a certain depth, while the core basically maintains the structure and properties before treatment, so a combination of high strength, high wear resistance and high toughness can be obtained. And because it is local heating, it can significantly reduce quenching deformation and reduce energy consumption.
