Alkali metal can be circulated and accumulated in blast furnace. In this work, the distribution of alkali in blast furnace is determined by the calculation of alkali balance. Combined with the cyclic of alkali in the blast furnace, the influence of alkali on coke ratio is calculated by using blast furnace operation line. The results show that the circulation of alkali in the blast furnace increases the coke ratio.
