Rocker shaft hardening by super audio frequency induction hardening machine

The rocker shaft is an important part of the engine and plays an important role in the operation of the engine. During the working process, the rocker shaft is subject to huge friction, therefore, the rocker shaft is required to have high hardness, wear resistance and service life. Now, many manufacturers use super-audio frequency induction hardening machine to quench and heat-treat the rocker shaft, and the effect is very good.

The so-called quenching is a heat treatment process in which the workpiece is rapidly heated to a certain temperature and then rapidly cooled, with the purpose of improving the hardness and wear resistance of the workpiece. The 120kw super audio frequency induction hardening machine produced by our company can carry out surface quenching heat treatment on the rocker shaft with a diameter of 90mm.

Advantages of super audio frequency induction hardening machine

1. Adopt digital phase-locking technology to realize automatic frequency tracking, and can automatically adapt to various sensors, which makes the equipment widely used in quenching, welding, diathermy, melting, etc. of workpieces.

2. Compared with the electronic tube induction heating equipment of the same power level, the volume is reduced by 1/2, the weight is reduced by 2/3, water is saved by 40%, and electricity is saved by 30%-40%. Such energy saving greatly reduces the Customer's production costs.

3. The super audio frequency induction hardening machine has a unique cooling circulation system to ensure that the equipment can work continuously for 24 hours.

4. The heating speed is fast, which can make the rocker shaft reach the required temperature in a short period of time, and the heating speed is uniform, which effectively avoids the phenomenon of oxidation and decarburization of the rocker shaft during the quenching process, and ensures the quenching of the rocker shaft effect.

5. The IGBT module is used, which is quite simple to operate and does not require manual training, which reduces the investment in training for enterprises.
