The grade of titanium slag may not meet the requirement in some short processes of titanium slag smelting.In order to solve the problem,a simulating experimental device of electric furnace was built under laboratory conditions to melt titanium slag,and pulverized coal was injected to the molten slag to improve its grade.The effect of coal injection amount and reaction time on titanium slag's grade was also investigated.Results show that the grade of titanium slag rises with the increase of the coal injection amount,and as the coal is injected,the grade of titanium slag rises before it falls.To be more specific, the grade of titanium slag rises from 70% to 82% after 7 kg of pulverized coal has been injected into 50 kg of molten slag at 1 600℃ for 20 minutes and reacted for another 20 minutes.This conclusion will provide a new way to improve the grade of titanium slag which is smelted by short processes.
