| 摘 要： | The new process for semiting Ti-Si ferroalloy using Panzhihua Iron & Steel Company (PISC) blast furnace titaniferous slag is introduced. The reduction and impoverishment law of TiO2 in slag and the effects of DC on smelting Ti-Si ferroalloy are studied when smelting Ti-Si ferroalloy by electrosilicothermal method,Ti-Si ferroalloy containing about 20% Ti can be produced by electrosilicothermal method. and Ti recovery rate is less than 60 %. And then, electrosilicoaluminothermal method is developed, by which Ti-Si ferroalloy containing Ti more than 30% and Si less than 35 % can be produced, and Ti recovery rate is higher than 80%. Ti-Si ferroalloy can replace TiFe martially in steelmaking,and residue slag can be used to make cement.
