摘　　要：研究了斜轧低铬白口铸铁磨球的制坯方法，轧制工艺及轧后余热热处理工艺。结果表明，最佳的制球工艺为，将经过一次小量预变形的金属型棒料，在1000～1050℃于较松的孔型中轧制成球，轧后在SST101介质中冷却，200～350℃回火。The making base method,rolling and heat treatment processes for grinding ballsof cross-rol1ed low chromium white iron,are studied. Result show that the best making ballprocess is to rol1 out the metal rod,which has been already defouned slightly, into balls at1000~1050℃,and then cool them in the SST101 medium,the balls are at last tempered at200~350℃.
