In this paper the smelting process of titanium-silicon (Ti-Si) ferroalloy using waste blast furnace titaniferrous slag containing higher than 20% TiO<SUB>2</SUB> is introsuced. Firstly the principle of smelting Ti-Si ferroalloy by electrosilicothermic method (ESTM) and the effects of DC on the reduction of TiO<SUB>2</SUB> in molten slag are studied. Ti-Si ferroalloy containing about 20% Ti can be produced by ESTM, and Ti recovery is less than 60%. And then, electrosilicoaluminothermic method (ESATM) is introduced. Ti-Si ferroalloy containing higher than 30% Ti and less than 35% Si can be produced by ESATM, and Ti recovery is higher than 80%. Studies on application of products (Ti-Si ferroalloy and residue slag) of the smelting process have been carried out, and the results show that the electrothermic smelting process can make the waste blast furnace titaniferrous slag be used perfectly.
