Study on the Application Technology Route for the Titanium Slag Reduced from Titanium Vanadium Iron Concentrate in Direct Reduction Process

The predecessors reported more about research on application technology roadmap of acid-soluble titanium slag and high titanium slag.There is no report on the use of 50 titanium slag from the direct reduction of non-blast furnace smelting technology,but there are no reports on the use of 50 titanium slag from the direct reduction of non-blast furnace smelting technology. Thus,this paper has investigated the application technology route of 50 titanium slag as raw material for the production of titanium products.At first,the chemical composition and phase of 50 titanium slag are studied,and then three main titanium production lines of 50 titanium slag are discussed,such as the preparation of 70 titanium iron,the preparation of titanium dioxide and titanium aluminum alloy. Using raw materials proportioning calculations and the theoretical composition calculations of the product study its feasibility.In addition,the effect of CaO on the content of slag has been studied,and the optimum content of CaO which is conducive to slag-alloy separation has been discussed.Finally,the environmental protection,energy consumption analysis and economic balance analysis of the three technical routes are discussed,and it is found that the preparation of titanium aluminum alloy with 50 titanium slag as the raw material is the best technical route program.
