高频感应加热炉淬火和中频感应加热炉淬火的区别

高频感应加热炉和中频感应加热炉都能对工件淬火，但和工件的所需硬化层深度有关，频率越高、其加热的深度越小。以轴类零件为例，一般的选择原则是，直径小于20mm的用高频感应加热炉，直径20~200mm的用中频感应加热炉

The difference between quenching in high frequency induction heating furnace and quenching in medium frequency induction heating furnace

Both high frequency induction heating furnace and medium frequency induction heating furnace can quench the workpiece, but it is related to the required hardened layer depth of the workpiece. The higher the frequency, the smaller the heating depth. Taking shaft parts as an example, the general selection principle is to use high-frequency induction heating furnaces with a diameter of less than 20mm, and medium-frequency induction heating furnaces with a diameter of 20~200mm.
