铸铁轧辊是轧辊的主要品种之一,年产量近20万吨,生产厂家在100家以上。轧辊质量直接影响轧机的作业率、轧材的精度和质量,因此世界各工业发达国家对提高轧辊的质量、开发新品种、探索新工艺都给予了极大的重视。我国也是如此,目前几个主要轧辊生产厂已掌握了离心铸造铸铁轧辊和大型球铁轧辊的先进制造技术,逐步地使轧辊材质和工艺技术换代。 Cast iron roll is one of the main varieties of roll, the annual output of nearly 200,000 tons, more than 100 manufacturers. Roller quality directly affects the rolling mill operating rate, precision and quality of rolled material, so the world’s industrialized countries to improve the quality of the roll, develop new varieties, to explore new technology have given great attention. The same is true in our country, at present several major roll manufacturers have mastered the advanced manufacturing technology of centrifugal cast iron roll and large ductile iron roll, and gradually make the roll material and technology replacement.
