Casting balls are extensive used in cement build materials, metal mine, coal slurry, thermal power plant, chemical engineering, ceramic industry, dope industry, light industry some as papermaking and magnetic material etc powder prepared and deeply produce. The casting ball??s hardness is high, and wearing cost is lowness, the toughness is very good so that the casting balls breakage is fewness. The surface hardness of ball will be raised further in using the course, and the wear resistance would gather hard, so can raise mill machine production capacity at the same time, and raises cement??s ratio surface area and reclaim ratio of the extractive mine. The products of ??FENGXING?? Band have seven series and more than one hundred specifications. It had been sold briskly to more than 2000 enterprises in country-wide for the high quality and also been exported to more then twenty countries such as Korea, United States, Australia, Southeast Asia and Africa.
