摘要
在钨铁冶炼中,采用白钨精矿替代部分黑钨精矿冶炼钨铁,通过改进工艺,在精炼取铁期和贫化期分别配加一定量的低磷、低氧化钙、高氧化铁等黑钨精矿和白钨精矿,可大幅度降低钨铁生产成本,并取得显著效益。
In smelting ferrotungsten,using sheelite concentrate to substitute partly wolframite concentrate.By reforming process,charging an enormous amount of low phosphorous,low calcium oxide and high iron oxide during refining,picking and diluting stages respectively,then can decrease the ferrotungsten production cost and obtain obvious benefit.
