摘　　要：论述了大型回转窑铸钢件托轮在生产过程中存在的质量问题。通过采取工艺措施,包括合理设置冒口、补缩通道、外冷铁,采用呋喃铬铁矿砂和宝珠砂等办法,重点解决铸件补缩、表面粘砂严重、裂纹等问题,生产出优质的托轮铸件。The quality problems of casting steel supporting roller for large rotary kiln was studied. The supporting roller is produced successfully by taking new technological measures, installing reasonable risers and feeding pathway, surface chills and using furan chrome ore sand and electric melting haydite sand, which especially solves the problems such as casting feeding, serious surface metal penetration and crack.
