我国是一个富钒国家,蕴藏着极为丰富的钒钛磁铁矿资源。钒作为合金元素加入钢中能使钢的强度提高,钢的晶粒细化,消除钢的过热倾向,并可改善钢的赤热硬性、耐磨及焊接性能,所以钒是使钢合金化的最重要的元素之一。钒作为合金元素常以钒铁形式加入钢中。 目前国内外现有的钒铁生产一般都是采用湿法提纯——火法冶炼这一工艺流程。这种工艺流程可以生产出含钒高、含杂质低的钒铁,但存在着化工原料消耗大、工艺复杂、流程
China is a vanadium-rich country, which contains extremely rich vanadium-titanium magnetite resources. The addition of vanadium as an alloying element increases the strength of the steel, the grain refinement of the steel, the tendency of overheating the steel and the improvement of the hot-red hardness, wear resistance and weldability of the steel, so vanadium is alloyed with steel One of the most important elements. Vanadium as an alloying element is often added to the steel as ferrovanadium. At present, the current production of ferrovanadium at home and abroad is generally wet purification - pyrometallurgical process. This process can produce high vanadium content, low impurity vanadium iron, but there is consumption of chemical raw materials, complex process, the process
