摘　　要：分析铸钢支承辊上辊颈产生缩孔缩松缺陷的原因。通过使用保温冒口,加大欠浇高度,采用高温钢水补浇,有效消除铸钢支承辊的缩孔缩松缺陷。This paper analyzes the reason for shrinkage hole and porosity defects occurred on journal of cast steel backup roll, and the defects are effectively eliminated by using insulating riser, increasing owe poured height and adopting high temperature molten steel for back pouring.

关 键 词：铸造支承辊 缩孔缩松 改进措施
