A New Technological Process for Smelting Ferro-Tungsten-Molybdenum

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 experiment results. The ferro-tungsten-molybdenum, obtained with Mo/W of 0. 05~0.5 at recovery of Mo and W 90% respectively, is applicable to smelting ahoy steel. This new technologicalroute is open to utilization of the W-Mo intergrowth mineral resource.
