(1) High-frequency quenching: put the weather-resistant steel plate into the high-frequency coil and turn on the high-frequency current, and the induced current is generated in the workpiece at this time. The high-frequency current is only concentrated on the surface of the weather-resistant steel plate, so as long as the surface of the weather-resistant steel plate is heated. This method of heating and quenching is called high-frequency induction heating quenching.

(2) Flame quenching: This is the quenching method of using the flame of oxygen and other gases to stop heating

(3) carburizing and quenching: In order to achieve the purpose of only increasing the carbon content of the weather-resistant steel plate, the weather-resistant steel plate is put into the carburizing agent to stop heating carburizing and quenching. Liquid carburizing agents such as solid carburizing agents such as charcoal and coke and gas carburizing agents such as CO are used as carburizing agents. Stop heating in this carburizing agent, and the carbon element will penetrate into the surface of the weather-resistant steel plate, which only makes the appearance of the weather-resistant steel plate become a high-carbon weather-resistant steel plate. The carburized quenching layer can reach a depth in millimeters.
