Tungsten-chromium alloy steel ball and preparing method thereof

The invention belongs to the technical field of metallurgy, and particularly discloses a tungsten-chromium alloy steel ball. The tungsten-chromium alloy steel ball comprises components including Q235tungsten steel, alloy steel scraps, a carburant, boron-chromium, a zirconium-silicon-chromium alloy, a magnesium-aluminum-calcium alloy and an yttrium-base heavy rare earth silicon-chromium alloy. Thetungsten-chromium alloy steel ball is prepared through the electric furnace smelting technology, and the prepared tungsten-chromium alloy steel ball is low in cost, good in abrasion resistance and suitable for large-scale industrial application. 本发明属于冶金技术领域，具体是公开特种钨铬合金钢球，其组分包含Q235钨钢、合金钢钢屑、增碳剂、硼铬、锆硅铬合金、镁铝钙合金及钇基重稀土硅铬合金。并进行电炉熔炼工艺制备钨铬合金钢球，制得钨铬合金钢球成本低、耐磨性好，适合大规模工业应用。
