摘　　要：针对以往大型钢锭模铸件内壁极易出现粘砂、夹砂、气孔、外表面极易有砂眼、缩孔及"胀肚"等缺陷,提出了大型钢锭模铸件铸造工艺的改进措施,使该铸件一级品达80%以上,废品率为零。Response to previous large-scale steel ingot casting wall appeared vulnerable sticky sand,coarse,stomatal,extreme outer surface of a trachoma,pipe and "bulging belly" and other shortcomings,This paper presents a large-scale Ingot Casting Process Improvement measures to make the casting a goods was more than 80%,reject rate to zero.
