摘要介绍了在ZGM113G-Ⅰ型中速磨煤机上先后使用过的三种不同材质的辊套和衬板，分析了辊套和衬板的化学成分及铸造工艺特点，对比了辊套和衬板的磨损速率、使用寿命以及磨损形状对磨煤机性能的影响。结果显示，高铬堆焊产品略优于高铬铸造产品，复合熔铸金属陶瓷产品远优于前两种产品，使用寿命可达16 070h，同时，大幅延长了检修周期，增加了磨煤机出力，降低了单位电耗，性价比高。

Abstract: Three kinds of roll sleeves and liners of different materials used successively in ZGM113G-I medium speed coal mill are introduced. The chemical composition and casting process characteristics of roll sleeve and liner were analyzed. The effects of wear rate, service life and wear shape of roll sleeve and liner on the performance of coal mill were compared. The results show that the performance of high chromium surfacing products is slightly better than that of high chromium casting products. Composite melt-casting cermet products are much better than the first two products. Their service life can reach 16 070h. At the same time, the maintenance cycle is prolonged greatly, the output of coal mill is increased, the unit power consumption is reduced and the performance price ratio is high.

Key words: coal mill wear high chromium surfacing cermet composite casting
