一、前言在钒钛磁铁矿冶金的新流程工艺研究中,采用铁精矿球团——链篦机回转窑或竖炉天然气还原,电炉熔化分离铁钛钒,用浸取法从熔化渣中提钒及氮化焙烧氯化法提钛工艺流程。熔化渣中富集了45～65％的TiO_2及2％左右的V_2O_5,为了调整电炉的还原气氛,不使钒钛进入铁液中,必须使渣中FeO的含量保持在3～9％左右,在熔化过 First, the preface In vanadium titanium magnetite metallurgy new process technology research, the use of iron ore pellets - grate rotary kiln or shaft furnace natural gas reduction, melting furnace separation iron titanium vanadium, leaching method from the molten slag Vanadium extraction and nitrogenation roasting process of titanium extraction titanium. The molten slag is enriched with 45-65% of TiO 2 and about 2% of V 2 O 5. In order to adjust the reduction atmosphere of the electric furnace, the vanadium and titanium should not enter the molten iron, and the content of FeO in the slag must be kept at about 3 to 9% Melted over
