摘　　要：根据当前重型轴类锻件在自由锻造中存在锻造精度低,锻造表面质量差,加工余量大,锻造火次多等问题,以支承辊锻件的拔长工序为例设计径向锻造工艺替代自由锻造,以减少拔长工序的锻造火次。再通过数值模拟验证径向锻造工艺应用的可行性,并确定了60 MN液压机配合使用径向锻造工具的锻造力和锻造直径等主要技术参数,为径向锻造工具的设计提供工艺数据。Because heavy shaft forgings made with current open-die forging technique have low forging precision, poor surface quality, large machining allowance, multiple heating times and so on, the paper takes the drawing-out step of backup roll forgings for example to establish a radial forging technique to replace the open-die forging technique in order to decrease the heating times during the drawing-out step. Numerical simulations were performed to verify the feasibility of the radial forging technique. The main technical data of the radial forging tools for 60 MN hydraulic press have been determined, such as forging force and forging diameter, which are used for the design of radial forging tools.
