Anyone who has seen a train knows that the train wheel is an important part of the train. The train mainly relies on it to move. During the running of the train, the train wheels have to bear huge friction all the time. For this reason, many manufacturers adopt medium frequency heating machine to carry out quenching heat treatment to train wheel now, and purpose is exactly to improve its hardness, wear resistance and service life.
Quenching is a heat treatment process in which the workpiece is heated to a certain temperature and then cooled rapidly. It is widely used in industry. The surface hardness of the train wheel quenched by the medium frequency induction heating machine is greatly improved, which meets the technical requirements of the train wheel.
The medium frequency induction heating machine is produced by advanced IGBT modules. When it quenches the train wheels, its quenching speed is very fast, which effectively avoids the oxidation and decarburization of the workpiece during the quenching process and ensures the safety of the train. The quenching effect of the wheel, and when it is quenching the train wheel, we can regulate the surface hardened layer by adjusting the working frequency and power of the medium frequency induction heating machine as needed. As a result, the martensite structure of the hardened layer is finer, and the hardness, strength and toughness are relatively high. What's better is that it will not produce noise and dust when it is working, which greatly improves the working environment of workers.
