Abstract:

The cognizing process of the relation between coke reactivity and blast furnace ironmaking is summarized. The effect of the coke with different reactivities on the ironmaking process of blast furnace and present study situation of technological means of the production of the coke with different reactivities are expounded. Through the discussion on the adaptability of the coke with different reactivities to the blast furnace ironmaking condition, it is put forward that the suitable coke reactivity should be specified according to the blast furnace ironmaking condition and reducing property of iron ore.
