一、前言钒钛磁铁矿高炉炼铁,由于渣中有高熔点的钒钛碳氮化物,从而形成粘渣及粘罐现象以及泡沫渣,钒钛铁矿的精矿球团,经竖炉还原得到的海锦铁中富集了钒钛氧化物,由电炉熔化分离铁,而渣中氧化钒可达2％左右,经氮化得到碳氮化钒是提钒的精料,这些工艺研究过程要作钒物相的定量分析。含钒钛的生铁,再加入过量钒(达到0.3～1.5％)及其他元素制成铸造铁,使其
First, the preface Vanadium Titanium Magnetite Blast Furnace Ironmaking, due to slag melting point of vanadium titanium carbonitride, resulting in sticky and sticky tank phenomenon and foam slag, vanadium ilmenite concentrate pellets, shaft furnace The reduced vanadium-titanium oxide is enriched in vanadium-titanium oxide by electric furnace, and the vanadium oxide in the slag is up to about 2%, and vanadium carbonitride obtained by nitriding is the concentrate to extract vanadium. These technologies are studied Process for the quantitative analysis of vanadium phase. Vanadium-bearing titanium pig iron, then add excessive vanadium (up to 0.3 to 1.5%) and other elements made of cast iron, making it
