目前,国内外所沿用的高炉或电炉冶炼钒钛磁铁矿,生产的含钒生铁需经雾化炉,转炉或摇包吹钒,钒渣配加钠盐经回转窑氧化钠化焙烧,水浸提取五氧化二钒流程,工序长[1]、成本高,钒产品价格昂贵,既限制了钒的应用,又限制了钒钛磁铁矿的大规模开发。本试验旨在研究喷吹氧气,同时配加碳酸钠脱除含钒铁水中的钒、硫和磷。钒形成可
Currently, the domestic and foreign used blast furnace or electric furnace smelting vanadium titanium magnetite, the production of vanadium-bearing pig iron through the atomization furnace, converter or swinging package blowing vanadium, vanadium slag with sodium salt roasted by sodium rotary kiln, water The process of extracting vanadium pentoxide by leaching, the length of the process [1], high cost and expensive vanadium products not only restrict the application of vanadium but also limit the large-scale development of vanadium-titanium magnetite. The purpose of this experiment was to study the blowing of oxygen while adding sodium carbonate to remove vanadium, sulfur and phosphorus from vanadium-bearing molten iron. Vanadium can be formed
