| 摘 要： | A study was carried out on the formation of Ti(C,N) during smelting vanadium-bearingtitanomagnetite in blast furnace and the influence of MnO content on reduction of TiO_2 inthe slag containing high titania. The reduction of TiO_2 is restricted by MnOpredominantly atthe slag-metal interface and no more at the slag-coke one. The formation of Ti(C,N) is remarkablyrestricted by MnO in the slag when the MnO content is about 4% and the basicityfrom 0.6 to 1.2 in the slag. MnO may also retards the reduction of SiO_2 and accelerates thedesulphidation under certain condition.
