Abstract：

The shape characteristics of railway wheel with considerable variability in the size between plate and rim were presented, the hot forming technology was studied and a correct solution to design the hot forming technology of this kind of wheel was worked out. Through simulated pre-forming process, the existence of metal neutral face was verified; the value of mobile radius could be used to optimize the design of pre-forming mould. During the forming process, forming ring mould design was based on the wheel flange shape. By analyzing the wheel rolling deformation, the roll web design principle was gained. After industrial production, the passing test for hot formed product reaches to 98% at least.
