一、前言云南锡业公司用烟化挥发法和高温氯化挥发法所产烟化炉废渣和氯化挥发焙球,目前年产量可达10万吨右左。烟化炉渣约含铁40％,焙球含铁45～50％。攀钢高炉冶炼钒钛磁铁矿产出高钛型泡沫渣或粘稠渣,给冶炼过程带来一定困难。为了改善炉况,配加10～15％的普通富铁冶炼获得了满意的效果。昆明冶金研究所与攀钢公司共同对泡沫渣的生成机理和消除方法的研究表明,配加适当量的普通富铁矿或硅酸盐物料,可改善渣的动力学性质,抑制TiO_2的过还原和稀释渣中TiO_2的 I. Preface Yunnan Tin Industry Co., Ltd. uses fume volatilization method and high-temperature chlorination volatilization method to produce fume furnace slag and chlorinated volatile baking balls, and the annual output can reach about 100,000 tons at present. Fuming slag about 40% iron, baking ball 45 ~ 50% iron. Pangang blast furnace smelting vanadium titanium magnetite output of high-titanium foam residue or viscous residue, to the smelting process to bring some difficulties. In order to improve the furnace condition, with 10 ~ 15% ordinary iron smelting obtained satisfactory results. Kunming Institute of Metallurgy and Panzhihua Iron and Steel Company common foam generation mechanism and elimination of foam research shows that with an appropriate amount of ordinary iron ore or silicate material can improve the dynamic properties of the slag and inhibit TiO 2 over-reduction And dilute the slag in the TiO_2
