一、前言 我国攀枝花一西昌地区的钒钛磁铁矿经处理后,所得含钛物料中钙镁含量较高(CaO+Mg05—9％),使制取四氯化钛的氯化过程具有一定特殊性。而四氯化钛是制取金属钛与钛白的中间产品。用沸腾氯化法生产,其炉产能已达25—30吨TiCl_4/日·米~2,分别为竖炉氯化法的7—10倍、熔盐氯化法的2倍左右。作为工业生产方法,沸腾氯化高钙镁含钛物料.(包括人造金红石与高钛渣)制取四氯化钛,国外尚无报道(只有苏联进行了制粒沸腾氯化的半工业试验,所用
I. Preface The vanadium-titanium magnetite in the area of Panzhihua-Xichang is treated with high content of Ca-Mg in the obtained titanium-containing material (CaO + Mg05-9%), so that the chlorination process of preparing titanium tetrachloride has certain Particularity. The titanium tetrachloride is the preparation of titanium and titanium intermediates. With boiling chloride production, the furnace capacity has reached 25-30 tons TiCl_4 / day · m ~ 2, respectively, 7-10 times the shaft furnace chlorination, molten salt chlorination 2 times. As a method of industrial production, boiling of high calcium and magnesium chloride containing titanium materials (including artificial rutile and high titanium slag) Preparation of titanium tetrachloride, foreign countries have not been reported (only the Soviet Union had granulation boiling chlorinated semi-industrial test, Used
