摘　　要：通过对米辊的材质选型、成形工艺、性能测试,确定了米辊的材料组成和成形工艺方法,获得了一种组织致密、韧性较好、硬度高的耐磨低铬铸铁米辊。试验结果表明,该米辊具有良好的耐磨性和韧性,解决了原来的冷硬铸铁米辊容易生锈和耐磨性差的问题。The material selection of rice roller, forming process, performance testing were analyzed, the materials and process for forming the rice roller were determined. The rice roller with compact structure, good toughness and high hardness has been obtained. The test results show that the rice roller has good abrasion resistance and toughness, and the problems that the original chilled cast iron rice roller is easy to rust and has poor wear resistance are solved.
