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20t工业电弧炉内完全用白钨矿、氧化钼、V205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（％）：W95.25，Mo98.01，V90．72，冶炼周期283min，电耗585kWh／t，成品钢材质量满足标准要求。The Industrial test of steelmaking 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 seheelite, molybdenum oxide and V2O5 ore has been carried out in a 20t eleetrie are furnace at Chongqing Special Steel. The results showed that the alloying rate was up to [W] ＋ [ Mo] ＋ [ V] = 13 %, the yield of W, M o 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.
