摘要： 通过改变装入制度、采用低碱度渣工艺和控制渣量等措施，实现了在重庆特钢20 t 工业电弧炉内完全用白钨矿、氧化钼、V₂O₅ 直接合金化冶炼M2(%:0.80~0.90C,3.8～4.4Cr,5.50～6.75W,4.5～5.5Mo,1.75~2.20V)高速钢，合金化率达到[W]+[Mo]+[V]=13% 合金元素收得率(%):W 95.25,Mo 98.01,V 90.72,冶炼周期283 min,电耗585 kWh/t,成品钢材质量满足标准要求

Abstract: The Industrial test of steel making of high speed steel M2(0.80～0.90C,3.8～4.4Cr,5.50～6.75W, 4.5~5.5Mo,1.75～2.20V)by direct reduction and alloying with scheelite,molybdenum oxide and V₂O₅ ore has been carried out in a 20 t electric arc furnace at Chongging Special Steel.The results showed that the alloying rate was up to [w] +[Mo]+[V]=13%,the yield of W,Mo and V alloying element was 95.25%,98.01% and 90.72% respectively,the average tap-to-tap time was 283 min,the electric power consumption was 585 kWh/t and the quality of products met the requirement of standard
