摘　　要：分析了轧制长材用短应力线轧机轧辊轴向窜动的原因,指出承受轴向力的轴承选型及与轴承座孔、拉杆、球面垫的配合是其主要原因。对于立式轧机,由于上下辊系的偏移引起的平行四边形也是轧辊轴向窜动的主要原因,为此,提出了解决立式轧机出现平行四边形问题的方案。The axial shift reason of short stress path mill for long product roiling was analyzed in detail, and the main factors were turned to be the loading axial force bearing selection, and chock hole, pole, sphere surface pad assembly. For vertical type mill, the parallelogram due to upper and bottom roll set displacement was also the main reason of axial shift. In particularity, the solution for this parallelogram was put forward.
