The Principle of the High Frequency Induction Hardening Machine and Technology.
May. 14, 2016
Before we introduce the high frequency induction hardening machine, we need to know what’s the induction heating. Induction heating is the process of heating an electrically conducting workpieces by electromagnetic induction. An induction heater consists of induction power supply and induction coil.
The high frequency induction hardening machine adopt the induction heating, and here is the working principle of the induction heating: put the workpieces into the inductor, the inductor is a hollow copper tube with 1000-30000Hz alternating current. With the uneven induction current distribution on the workpieces, which can heat the surface rapidly. The temperature can be high up to the 800-1000℃ within several seconds while the core part of it has a little temperature rise.
