我国水泥年产量达1.8亿吨,名列世界前茅。但由于装备落后,机械零件的磨料磨损大得惊人,生产1吨水泥的钢铁材料磨耗高达1～1.5公斤,每年因此消耗钢材约30万吨,相当于一个中型钢铁厂的年产量。而国外生产1吨水泥的耐磨材料消耗量不到100克,相差10多倍。水泥总产量的80％又系中小厂生产的,所用耐磨零件仍是碳钢球,较多的耐磨件制造厂仍生产传统的高锰钢,甚至普通低碳钢
China’s annual output of cement reached 180 million tons, ranked among the best in the world. However, due to the outdated equipment, abrasive wear on mechanical parts is staggering. Steel materials producing 1 tonne of cement consume as much as 1 to 1.5 kilograms, consuming about 300,000 tons of steel each year, equivalent to the annual output of a medium-sized steel plant. Abroad production of 1 ton of cement wear-resistant materials consumption less than 100 grams, a difference of more than 10 times. 80% of total cement production is also produced by small and medium-sized factories, the wear-resistant parts used are still carbon steel balls, and more wear-resistant parts factories still produce traditional high-manganese steel, even ordinary mild steel
