| description | PROBLEM TO BE SOLVED: To provide a method for manufacturing a blast furnace coke capable of providing a high strength blast furnace coke at low cost while reducing effects of expansion on a coke oven.SOLUTION: The method for manufacturing a blast furnace coke has a process of blending ashless coal obtained by a solvent extraction treatment of coal with coal and a process of dry distilling the blended coal and the blended amount of the ashless coal in the blending process is 3 mass% or more and an expansion rate of the blended coal is 20% or less. It is preferable that the expansion rate of the blended coal in the blended process is 10% or more. The coal to which the ashless coal is blended preferably contains a heavy coking coal and non-slightly-caking coal and a percentage of the heavy coking coal in the blended coal preferably is 20 mass% to 50 mass%.
【課題】膨張によるコークス炉への影響を抑えつつ低コストで高強度の高炉用コークスが得られる高炉用コークスの製造方法を提供する。【解決手段】本発明の高炉用コークスの製造方法は、石炭の溶剤抽出処理により得られる無灰炭を石炭に配合する工程、及び上記配合炭を乾留する工程を備える高炉用コークスの製造方法であって、上記配合工程における上記無灰炭の配合量を３質量％以上、かつ配合炭の膨張率を２０％以下とすることを特徴とする。上記配合工程における配合炭の膨張率を１０％以上とするとよい。上記無灰炭を配合する石炭が強粘結炭及び非微粘結炭を含むとよく、上記配合炭における強粘結炭の割合としては２０質量％以上５０質量％以下が好ましい。【選択図】図２ |
