摘　　要：辊道是中厚板生产中不可缺少的部件,工作环境恶劣,尤其是机前机后辊道,除热辐射外还有氧化铁皮及油水侵蚀,并且承受很大冲击。用有限元软件模拟计算了辊道在冲击载荷作用下的等效应力,详细分析机前机后辊道受冲击和轧件头部弯曲之间的关系、轧件头部弯曲的原因,提出了几种有效控制轧件头部弯曲的方法。　the roller table, as an indispensable component to plate rolling mills, operates at harsh condition. Especially, the roller tables in front of and behind mill stands have to bear heat radiation and scale, oil and water corrosion as well as great impingement. Finite element analysis software is used to calculate the equivalent stress on the roller table under impact load, study the relation between the impingement on the roller table and bent head end of the slab to be rolled and the cause of the head bending. The article gives several proposals to eliminate the head bending of the slab to be rolled.
