A method for blast-furnace melting includes charging into the blast furnace of the charging materials, which contain coke, and blowing into the hearth with blast of the pulverized coal fuel. Pulverized coal fuel is blown into the hearth, ratio of the ash content in which to the ash content in the coke, which is charged is not more than 0.9, and ratio of the sulfur content in which to the sulfur content in coke, which is charged is not more, than 0.9. Ratio of the content of volatile matters in the pulverized coal fuel, which is blown in, to the content of volatile matters in the charged coke is of 10-25. |
