The pulley, which belongs to the hub type parts, is generally relatively large in size. During the operation of the car, it needs to bear huge friction. Therefore, the production usually requires the pulley to have high anti-wear performance, high compression resistance and long service life. In order to meet the above requirements and ensure the normal operation of the car, many manufacturers use super-audio frequency induction hardening power supply to quench the pulley, and the effect is good.
The super-audio frequency induction hardening power supply performs quenching heat treatment on the pulley, and the relatively common scanning quenching is adopted. With this method of quenching heat treatment, a hardened layer of about 2 mm can be formed on the surface of the pulley. It is precisely because of this layer of hardened layer that the hardness, wear resistance and service life of the pulley have been greatly improved.
Compared with the electronic tube induction heating equipment of the same power level, the super-audio induction hardening power supply is 1/2 smaller in size, 2/3 lighter in weight, 40% water saving, 30%-40% electricity saving, and occupies a small area , easy to operate, you can learn it in a few minutes. When the belt pulley is quenched and heat-treated, it uses electric heating, so there is no polluting gas and no waste, which greatly improves the working environment of workers.
