PRODUCING METHOD OF BLAST FURNACE COKE"

Abstract

A producing method of blast furnace coke includes classifying an inertinite, which has a maximum length of 0.6 mm or more, into a size class of a size classification number m according to a maximum length; determining an influence factor Ai (-/vol.%) of an inertinite in the size class i on a ratio of surface breakage product DI150-6 in advance with respect to all size classes i; measuring an amount Ibij (vol.%) of the inertinite in every size classes i with respect to all of the brands of raw-material coal; crushing the raw-material coal according to a boundary value of the amount of the coarse inertinite; measuring an amount Iaij (vol.%) of the inertinite in every size classes i with respect to all of the brands j of raw-material coal after being crushed; and blending all of the brands j of raw-material coal after being crushed in a maimer such that DI150.6 (target)- DI150-e (ref) = Σj=i to n{Σi=1 to m Aix(Ibij-Iaij)}xXj is satisfied.
