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 preparation method, rolling process and heat treatment process of post-rolling residual heat were studied. The results show that the best ball-making process is that after a small amount of pre-deformation of the metal bar, at 1000 ~ 1050 ℃ in a loose hole rolling into a ball, after rolling in the SST101 medium cooling, 200 ~ Tempering at 350 ℃.
