高铬铸铁具有良好的耐磨性,但它是一种脆性材料,薄壁的高铬铸铁还有巨大的开裂倾向,铸造难度较高。本文介绍了通过成分选择和工艺控制,成功铸造出外观无缺陷、不开裂、尺寸合格和硬度达标的薄壁高铬铸铁管件。 High chromium cast iron has good wear resistance, but it is a brittle material, thin-walled high-chromium cast iron there is a huge tendency to cracking, casting more difficult. This paper describes the successful casting of thin-walled, high-chromium cast iron pipe fittings with defect-free appearance, non-cracking, size conformity and hardness achieved through component selection and process control.
