Abstract
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 .
