针对进口高铬铸铁矿渣立磨辊套存在的易磨损问题,通过合理的成分设计和热处理工艺设计,在国内研发出高铬铸铁磨辊套制作材料。两年的工业试运行试验表明,该高铬铸铁磨辊套使用寿命是进口Cr15Mo2Cu高铬铸铁磨辊套的2倍以上。
In view of the easy abrasion problem of the imported high chrome cast iron slag vertical grinding roller sleeve, the high chromium cast iron roller sleeve material is developed in China through reasonable composition design and heat treatment process design. Two years of industrial trial run tests show that the high chromium cast iron roller sleeve life is imported Cr15Mo2Cu high chromium cast iron roll cover more than 2 times.
