It was very difficult for the smelting of vanadiumbearing titanomagnetite by blast furnace 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 vanadiumbearing titanomagnetite by blast furnace were obtained and improved gradually. With the improvement of beneficiated material level and equipment level, smelting intensity has been increased gradually and the highest comprehensive smelting intensity reached 145 t/(m3·d). Technicaleconomic indexes of blast furnace have also been increased remarkably. The highest utilization coefficient exceeded 27 t/(m3·d) on the condition that the burden grade was only about 50%.
