摘要
简单介绍了钨钼在合金钢中的使用情况,阐述了用三相交流工频等离子技术冶炼钨钼复合铁合金的机理及使用由钨精矿和钼精矿组成混合炉料直接制取钨钼复合铁合金的扩大量试验和分析结果。钨钼复合铁合金的Mo／W质量比为0．05～0．50，钨和钼的直收率高于90％，能满足冶炼合金钢的要求，为钨钼共生矿资源的利用，探索了新的冶炼工艺。
The paper introduces the use of W and Mo in alloy steel, describes the mechanism of ferro-tungsten-molybdenum smelting in three-phase AC working frequency plasmafurnace directly with mixed charge of W and Mo concentrates and gives the pilot experimentresults. The ferro-tungsten-molybdenum, obtained with Mo/W of 0. 05~0. 5 at recovery ofMo and W>90% respectively, is applicable to smelting ahoy steel. This new technologicalroute is open to utilization of the W-Mo intergrowth mineral resource.
