Road wheels are usually used in gantry cranes, bridge cranes, and mining machinery. They must bear huge friction during work. Therefore, they are generally required to have high hardness, and have a certain depth of hardened layer and transition layer. (depth>10mm, hardness HRC40-48). In order to meet these working requirements of driving wheels, many manufacturers perform quenching heat treatment on them. However, in practical applications, the road wheels always have defects such as short service life, deformation and cracks, which affect the normal operation of cranes and mining machinery.
With the continuous improvement of production technology, people have higher and higher requirements for road wheels. In response to this, people have developed a medium frequency induction heating machine. The medium frequency induction heating machine is used to quench and heat-treat the road wheels. After quenching, the hardness reaches HRC40-48, and the service life is 2-3 times that of traditional equipment. The most important thing is that its bearing capacity, wear resistance and contact fatigue resistance are better. Great improvement.
Why is the quality of the road wheel improved to such a large extent by using a medium frequency induction heating machine for quenching heat treatment? This is mainly due to the fact that the medium frequency induction heating machine is a high-tech equipment produced with advanced IGBT modules. During the quenching process, the heating speed is very fast, which effectively avoids the occurrence of oxidation and decarburization, and ensures the quenching of the road wheels. effect, and the deformation is also greatly reduced, almost to 0.
