钒钛铁水一般含硫较高,能脱硫又是现行火法提钒工艺的弊病之一,致使提钒后的铁液(俗称半钢)含硫更高,硫高是导致半钢炼钢经济技术指标较差的原因之一。为此。进行了喷吹纳盐脱硫试验。试验结果表明,先将钒钛铁水喷吹纳盐予脱硫,再按现行火法提钒炼钢工艺组织生产,即能获得优质低硫半钢,又能提高钒渣品位。为半钢炼钢扩大品种,提
Vanadium titanium hot metal generally higher sulfur, desulfurization is the current fire method to mention vanadium one of the drawbacks of the process, resulting in vanadium extraction of liquid iron (commonly known as semi-steel) higher sulfur, sulfur is the result of semi-steel steelmaking economy One of the reasons for the poor technical indicators. to this end. Sprayed sodium salt desulfurization test. The test results show that the first injection of vanadium and titanium molten iron salt desulfurization, and then the current fire method to mention vanadium steel production process, that is, to obtain high-quality low-sulfur semi-steel, but also improve the vanadium slag grade. For the semi-steel steel to expand varieties, mention
