我国研制的衬板在水泥磨机上的使用寿命已达到不低于进口材板的水平。目前，我国大多数水泥厂已采用国产耐磨钢材板，取代传统的高锰钢材板，取得了可观的经济效益。但是在湿磨工况下的磨料磨损及耐磨材料研究工作方面，我国开展得较晚，目前我国少数科研单位及大型企业正在开? China’s development of the liner in the life of the cement mill has reached no less than the level of imported timber. At present, most cement plants in China have adopted domestic wear-resistant steel plates to replace the traditional high-manganese steel plates and achieved considerable economic benefits. However, in wet grinding conditions abrasive wear and wear-resistant materials research work carried out late in our country, at present a small number of scientific research units and large enterprises are being opened?
