Progress in technologies of Vanadium-Bearing titanomagnetite smelting in PanGang

The smelting of vanadium-bearing titanomagnetite by blast furnace was very difficult because the content of TiO2 of blast furnace slag could amount to 20-25%. After long term development and continuous improvement, special intensified smelting technologies for vanadium-bearing titanomagnetite by blast furnace were obtained and improved gradually. With the improvement of beneficiated material and equipment, smelting intensity has been increasing gradually and the highest comprehensive smelting intensity that is fuel comsumption per unit useful volume per day reached 1.45t/(m(3).d). Technical-and-economic indexes of blast furnace have also been increasing remarkably. The highest monthly utilization coefficient exceeded 2.7t/(m(3).d) on the condition that the burden total ferrum grade was only about 50%.
