Beschreibung
Zusammenfassung:	The invention belongs to the field of chemical industries, and especially relates to a nanometer silicon nitride ceramic reinforcing steel ball. The steel ball comprises the following components in percentage by mass: Q235 tungsten steel, alloy steel chips, carburant, boron chromium, zirconium silicon chromium alloys, magnesium aluminum calcium alloys, yttrium base heavy rare earth silicon chromium alloys, and mixed ceramic powder. The steel ball is suitable for grinding iron ores, pulverized coals and cement clinkers; and no ball crushing phenomenon occurs in the use process. 本发明属于化学工业领域，特别涉及种纳米氮化硅陶瓷强化钢球，该钢球包含下述成分：按质量百分比为Q235钨钢，合金钢钢屑，增碳剂，硼铬，锆硅铬合金，镁铝钙合金，钇基重稀土硅铬合金，混合瓷粉。本发明的钢球适用于研磨铁矿石、煤粉和水泥熟料，使用过程中无碎球现象出现。
