摘要
PROBLEM TO BE SOLVED: To provide a method for manufacturing a carbon-containing nonfired agglomerated ore for blast furnace in which the carbon-content is high and the hot-crushing strength after reducing operation in the blast furnace is high.;SOLUTION: There is provided a method for manufacturing the carbon-containing nonfired agglomerated ore for blast furnace, by adding and mixing a binder and water into a raw material including fine powdery iron oxide and fine powdery carbonaceous material and granulating. In the method for manufacturing the carbon-containing nonfired agglomerated ore in which the coal-char is used, the fine powdery carbonaceous material includes the coal-char, which is possesed as 20-60 mass% to the total mass of the fine powdery carbonaceous material.;COPYRIGHT: (C)2014,JPO&INPIT
