摘要
在白口铸铁的基础上,加入多种少量其它合金元素,通过电炉熔炼和适当的热处理而获得的一种新型抗磨铸铁,其性能达到:HRC58～60,a_k>10J/cm^2,该合金铸铁具有成本低,抗磨性能好,利润率高,在建材机械、冶金矿山、耐火材料等工业部门具有广泛的应用前景,是中、低冲击应力条件下高锰钢和高铬铸铁的理想替代材料.
A new type of wear-resistant cast iron has been devoloped recently by making use of a new technological process.This kind of cast iron is made by adding up a small amount of alloying elements to the ordinary white iron,smelted by means of electric furnace and heat treated after casting.It has much better mechanical properties such as the hardness is up to HRC 58-60 and a >10J/cm^2.This kind of alloyed iron has a lot of advantages in lower cost,good wear-resistance etc.so that it will have a wide use and good prospect in industrial production,especially in the production of building industry,metallurgical and mining industry,and the production of refractory materials.Thus it will probably be an ideal substitute for high-manganese steel and high-chromium cast iron under medium and lower impact stress.
