摘　　要：通过对某钢管厂从德国引进的１５２．５ＢＲ圆孔型系统的主变形单机架轧制过程模拟，结果为：在圆周方向上管子的等效塑性应变分布不均匀，存在着一定的附加变形，在辊缝位置处的等效塑性应变最大；经减径后管子沿圆周方向的壁厚分布不均匀，在辊缝位置处的壁厚为最大值；经叠加后产生内六方趋势．实际生产轧制试验验证了有限元模拟结果的正确性．On the base of finite element simulation for one stand of 152.5BR passes system in stretchreducing mill, the distribution of equivalent plastic strain and tube wall thickness along the section is uneven. The position of maximum is located at the gap of roll. After changing the position at gap and root of roll and adding up, it results in polygonization of the wall thickness. Rolling tests for 152.5BR passes systems validate the result of finite element simulation.
