一、前言我国每年用于制造破碎矿石、煤粉和水泥等物料的易损件,要消耗几十万吨钢材。因此提高易损件的使用寿命或降低其成本,是一项迫切的任务。白口铁具有优良的抗磨性能,而被广泛应用于矿山、水泥、冶金和水电等工业中制作抗磨零件,并且应用范围日益扩大,代替了许多过去用高锰钢及低合金钢的产品。多年来,我们对白口铁进行了一系列的研究,并立足于国内富有的资源硼,提出了硼白口铁的几组化学成分,在磨球、灰渣泵、除砂器、漏斗等上的应用都获得了比较好的结果。
I. Preface China annually uses hundreds of thousands of tons of steel to manufacture wearing parts of crushed ore, pulverized coal and cement. Therefore, to improve the service life of wearing parts or reduce the cost is an urgent task. White iron with excellent wear resistance, and is widely used in mining, cement, metallurgy and hydropower industries such as the production of anti-wear parts, and the growing range of applications, replacing many in the past with high manganese steel and low alloy steel products . Over the years, we have carried out a series of studies on the white iron and, based on the abundant boron resources in our country, proposed several chemical compositions of boron white iron. On the grinding ball, ash pump, desander, funnel, etc. The application has obtained the better result.
