采用含钒转炉钢渣生产含钒生铁的方法
摘要：
本发明涉及采用含钒转炉钢渣生产含钒生铁的方法，属于冶金领域。本发明所解决的技术问题是提供了一种采用低品位含钒转炉钢渣生产含钒生铁的方法。本发明采用含钒转炉钢渣生产含钒生铁的方法包括如下步骤：a、物料配料：将含钒转炉钢渣、含铁物料、焦炭、河砂和萤石按一定重量配比混匀；b、冶炼：a步骤的各物料加热至1600～1650℃并保温2～4h进行冶炼，得到渣铁和铁水；c、分离：b步骤所得渣铁与铁水分离，铁水冷却得到含钒生铁。本发明方法工艺步骤简单，为含钒转炉钢渣特别是低品位含钒转炉钢渣中的钒资源的回收利用提供了一种新的途径，具有广阔的应用前景。
摘要（英）：

The invention relates to a method for producing vanadiferous pigiron by adopting vanadiferous converter steel slag, which belongs to the field of metallurgy. The invention aims to provide a method for producing vanadiferous pigiron by adopting low-grade vanadiferous converter steel slag, comprising the following steps of: a, material mixing: evenly mixing vanadiferous converter steel slag, ferruginous materials, coke, river sand and fluorite in a certain weight proportion; b, smelting: heating the materials in the step a to the temperature of 1600-1650 DEG C, and preserving the heat for 2-4 hours for smelting to obtain iron scraps and molten iron; and c, separation: separating the iron scraps and the molten iron obtained in the step b, and cooling the molten iron to obtain vanadiferous pigiron. The method of the invention has simple technical steps, supplies a new way for recovering vanadium resources in the vanadiferous converter steel slag, in particular low-grade vanadiferous converter steel slag, and has wide application potential.
