摘要
钒钛磁铁矿中的钒主要是以V尖晶石的形态存在。热力学计算表明:钒氧化物的还原在铁氧化物还原完成后才能开始进行,高炉渣内的V只能用C直接还原。对V在高炉炉渣中的还原过程进行了研究,找出了炉渣温度、炉渣CaO/SiO2、MgO、Al2O3和TiO2含量对V还原过程的影响。
The vanadium in vanadium titano - magnetite is mainly appeared as V - sinpel. It is showed from thermodynamic calculation that the reduction of vanadium oxide just begin only after that of ferric oxide fulfills; the vanadium in blast furnace slag can be only reduced directly with carbon. The vanadium reduction in B.F. slag is researched, the influences are found out of slag temperature, contents in slag of CaO/SiO2, MgO, Al2O3 and TiO2.
