Abstract Studies were carried out of the formation of Ti(C,N) during smelting V-bearing titanomagnetite in blast furnace and the influence of MnO content on reductionof TiO_2 in the high titania containing slag. The reduction of TiO_2 is restricted byMnO predominantly at the slag/metal interface and no more at the slag/coke one.Both the MnO content about 4% and the basicity from 0.6 to 1.2 in slag may re-markably restrict the formation of Ti(C,N). MnO may also retard the reduction ofSiO_2 and accelerate the desulphidation under certain condition.

Key words: blast furnace smelting TiO_2 reduction MnO slag
