摘　　要：在"低温慢浇"的客观条件下,阶梯式浇注系统更能保证轧机机架的铸造质量。但阶梯式浇注系统易使充型过程不平稳。通过对轧机机架3种不同的阶梯式浇注系统流场进行Procast有限元模拟,得出了能保证钢液自下而上逐层平稳充型的阶梯式浇注系统的结构。Under the condition of low pouring temperature and low pouring speed, mill housing could have good casting quality by using step gating system. But the step gating system made the filling process become more unstable. By using the ProCast software to simulate the flow field of rolling mill housing in three kinds of different step gating systems, the good structure of the step gating system was obtained, which can ensure the molten steel fill stably from bottom to top.
