It is studied in this paper that the influences of various factors,such as the smelting temperature,the basicity of the slag,and the quantity of reductant on the titanium content of alloy,silicon content of alloy,TiO2 content of the remaining slag and the titanium recovery in smelting silico-itanium ferroalloy using silicoaluminium ferroalloy as reductant.With this study,the optimum techn ological parameters are obtained of raising the titanium content of alloy and re-$$$ucing the silicon content of alloy. The stable experiments in laboratory and factory using this opti-mum technological parameters are conducted.
