摘　　要：钢球在工业中的应用非常广泛,特别是矿山用的球磨机对钢球的应用量更是巨大,由于其形状的特殊性,其大批量生产工艺也越来越得到重视。本文应用有限元方法,并基于楔横轧原理对钢球的轧制成形工艺过程进行模拟仿真,通过DEFORM-3D的模拟过程研究了楔横轧各工艺参数对钢球成形过程的影响,根据模拟过程中金属的流动规律对模具进行改良,获得满意效果。The finite element method has been adopted to simulate the ball rolling process on the basis of cross wedge rollingprinciple. The influence of various process parameters of cross wedge rolling on the form- ing process of steel balls has been studied by DEFORM-3D simulation. The die has been improved accord- ing to the metal flow law in the simulation process, which obtains satisfied effect.
