摘　　要：针对工作辊轴承座出现裂纹的问题,通过对不同工艺的对比,分析了冒口和冷铁的位置对缺陷产生的影响,并利用华铸CAE软件对轴承座铸造工艺进行了凝固模拟分析。将优化后的铸造工艺应用于实际生产中,有效减少了产品的缺陷,提升了产品质量。For the issue of appearing the cracks on the work roll chock, the influence of positions of riser and chill- ing block on detects has been analyzed by comparing different processes. Meanwhile, the solidification simulation anal- ysis of casting process of work roll chock has been carried out by means of CAE. The optimized casting process has been used in the actual production, so as to effectively reduce the defects and improve the quality of products.
