Electromagnetic heaters can be used for quenching mechanical parts and have been widely used in the industrial field. Compared to traditional flame quenching or conduction heating quenching, electromagnetic heaters have many advantages, such as:

1、 Fast heating speed: Electromagnetic heaters can quickly generate high-strength magnetic fields, which heat the surface of objects through eddy currents and Joule heat, greatly accelerating the heating speed.

2、 Uniform heating: The electromagnetic heater can control the transmission and absorption of electromagnetic waves by adjusting the magnetic field and frequency, resulting in a uniform increase in temperature on the surface of the parts, ensuring the quenching effect and quality.

3、 Good repeatability: Compared to the uncertainty of traditional flame quenching, electromagnetic heaters can achieve very precise heating control by controlling the electromagnetic field and frequency, thus achieving highly controllable and reproducible heating.

4、 Can meet the heating needs of complex objects: Electromagnetic heaters can meet the heating needs of objects of various shapes, sizes, and complex geometric structures, which traditional flame and conduction heating equipment cannot meet.

5、 Heating method is safe and reliable: Compared to flame quenching, electromagnetic heaters do not require an open flame to ignite and do not produce harmful gases and sparks, making them safe and reliable.

Therefore, as a new type of quenching method, electromagnetic heaters have many advantages and can be applied to the quenching treatment of high alloy steel, stainless steel, high-speed steel and other materials with more complex physical properties such as tetrahedron, cementite, and inclusion.
