The screw is an important part of the car, generally composed of a cylinder and a thread. During the operation of the car, the screw has to bear strong friction and certain corrosion. Therefore, the production usually requires the screw to have high temperature resistance, corrosion resistance, high service life and strength.
In order to meet the needs of screw work, many heat treatment manufacturers use high-frequency induction hardening machines to quench and heat-treat it. After quenching by this equipment, there is a thick hardened layer on the surface of the screw, and the service life is 3-5 times that of traditional heat treatment. More importantly, the strength and hardness of the screw after heat treatment are enhanced, so it is not afraid of wear and tear during the operation of the car and becomes more durable!
Compared with the electronic tube induction heating equipment of the same power level, the high-frequency induction hardening machine is 1/2 smaller in volume, 2/3 lighter in weight, 40% water saving, 30%-40% electricity saving, and occupies a small area. The operation is simple and can be learned in a few minutes. Even better, the quenching method is very flexible when the screw is quenched and heat treated. Not only can the screw be quenched and heat treated as a whole, but also partial quenching and heat treatment can be performed, which can meet the requirements of different customers and avoid waste of resources.
