摘要
介绍了利用钨酸和人造白钨 ,在真空炉内以碳还原制取钨粉和碳化钨粉的探索性工艺试验。结果表明 ,真空碳还原WO3,在 1 40 0℃真空度为 1 3 3Pa～ 1 33Pa的条件下 ,采用缓慢升温的还原、碳化工艺是可行的 ,所得产品可满足铸造碳化钨的使用要求。
It introduces the process experiment for producing C and WC powder in vaccum electric furnace with W 2O 3 and artificial scheelite reduced by carbon .The result shows that it is feasible to reduce WO 3 with reduction and carbonation process in the condition of 1400℃,13 3～1 33Pa vacuity and rising temperature slowly.The products can meet the needs of casting wolfram carbide.
