How to use the preparation method of railway wheels?

2022-02-11

The company has developed a method for the production of railway wheels, which includes the steps of billet cutting, billet heating, forming, rolling, slow cooling or isothermal treatment, heat treatment and finishing. In the preparation method, rough machining is cancelled, and an appropriate increase in the finishing allowance can increase the machining allowance of the tread surface after heat treatment, and more metal near the surface of the tread can be removed under the condition of satisfying the requirements of machining accuracy, which is more conducive to reducing or eliminating the tread surface. Depth of lower abnormal tissue area. Compared with the conventional process, when the performance index of the wheel prepared by the invention is basically the same, the depth of the abnormal tissue area under the tread is obviously reduced, and the consumption of finishing tools is reduced.
