白钨矿和氧化钼直接还原合金化的理论分析及工业试验

THEORETIC ANALYSIS AND INDUSTRIAL TRIAL OF DIRECT REDUCING AND ALLOYING OF SCHEELITE AND MOLYBDENUM OXIDE

对白钨矿和氧化钼直接还原合金化进行了热力学和动力学计算和分析。炼钢过程中，［Ｃ］、［Ｓｉ］、［Ａｌ］都能还原白钨矿和氧化钼。（ＷＯ３）和（ＭｏＯ３ ）还原过程的限制性环节分别是ＷＯ３ 及ＭｏＯ３ 在熔渣中的扩散。并成功进行了全部用白钨矿和氧化钼冶炼高速钢Ｍ２（Ｍ２Ａｌ）的工业试验。

Direct reducing and alloying of scheelite and molybdenum oxide is considered by thermodynamic and kinetic calculation and analysis in this paper Scheelite and molybdenum oxide can be reduced by [C],[Si]and [Al] in the process of smelting steel Diffusion of (WO 3) and (MoO 3) is the restrictive step in the process of reducing (WO 3) and (MoO 3) Industrial trial has been conducted successfully for smelting high speed steel M2(M2Al) with scheelite and molybdenum oxide completely.
