摘　　要：介绍了高铬耐磨铸铁辊套的生产工艺。通过合理选择Cr20材质的化学成分、结合高铬铸铁的凝固特性制定铸造工艺及热处理工艺,实现了辊套在铸态下硬度>53 HRC,热处理后硬度>61 HRC,确保辊套无损检测合格。铸件品质达到国内同类产品先进水平。The production process for high-chromium cast iron roller was introduced. By choosing chemical composition of Cr20 material reasonably and developing casting process and heat treatment process via combining solidification characteristics of high-chromium cast iron, the targets which are the roller hardness 〉53 HRC in the cast state and 〉61 HRC after heat treatment can be achieved, making sure the roller non-destructive testing qualified as well, and the casting quality achieve the advanced level of domestic equivalent products.
