摘　　要：Defibrator is a very important machine in the wood industry for producing fiberboard. The refiner plates are the key parts of defibrator that directly act with the wood, and broken easily. The working life of the refiner plates is of significance to the wood industry. It may affect refining quality, production efficiency, and power consumption. In this paper, the abrasion resistance of the refiner plate made of different materials, the stainless steels and high chromium cast irons, were tested and compared. The results showed that abrasion resistance of refiner plate made of high chromium cast irons was better than that of the stainless steel materials. Although the two kinds of materials have the same compositions, their abrasion resistances have ap-parent difference. The main reason is that the material microstructures have very important effects on their performance. The refiner plates made of developed high chromium cast irons don抰 demand the complex heat treatment. This can simplify the producing process, save the cost of production, decrease labor strength, and increase the production efficiency.在木材工业中,热磨机是生产纤维板非常重要的机械,而其磨片是直接与木材作用的零件,容易损伤。因此,磨片的使用寿命对木材工业生产纤维板来说具有重要意义。例如,它影响制浆质量,生产效率以及能耗。本文研究主要集中在磨片材质的耐磨性上。通过对热磨机磨片材质不锈钢以及开发的高铬铸铁耐磨性比较,结果表明:高铬铸铁比不锈钢有好的耐磨性;尽管材料含有相同的成分,但耐磨性也是不同的,是因为材质的微观结构对性能具有重要的影响。同时也指出,开发的高铬铸铁制造的磨片不需要复杂的热处理,这能简化生产工艺,节约生产成本,降低劳动强度以及提高生产效率。图6表2参6。
