Rocker shaft is the important part in engine of the car, and the main role is to support the rocker arm. And the main role of the rocker arm is to facilitate to adjust the size of the valve opening. Rocker shaft's work environment is very bad, so it needs to withstand the huge friction and corrosion resistance. At this time, how to improve its wear resistance has become the most important issue.
Quenching is the only way to improve the hardness and wear resistance of the rocker shaft. The study found that, after quenching by high frequency idnuction heating machine, the rocker shaft surface will produce a protective layer of about 2mm. And it is the protective layer that makes the rocker shaft hardness and wear resistance are greatly increased.
Rocker shaft uses this machine for quenching heat treatment, and in quenching process, the equipment will not produce exhaust gas, smoke, etc., quite environmentally friendly. And it can greatly improve the customer's work environment. Compared with the traditional equipment, it avoids the oxidation phenomenon, and the rocker shaft reject rate is greatly reduced, avoiding the waste and reducing the production cost.
