| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a pretreatment method for coke to improve its reactivity.SOLUTION: A method for pretreating coke to be charged into a blast furnace, comprising a spraying step 100 of spraying an organic binder on the coke, a first mixing step 200 of mixing coke wetted with a binder with a mill scale and attaching the mill scale around the coke, in which the coke is small to medium lump coke having a particle size of 10 to 35 mm, and a second mixing step 300, subsequent to the first mixing step 200, of mixing the mill scale-attached coke with a sintered ore.SELECTED DRAWING: Figure 1
【課題】コークスの反応性を向上させるコークスの前処理方法を提供する。【解決手段】高炉に装入するコークスの前処理方法であって、コークスに有機系のバインダーを散布する散布工程１００と、バインダーで濡れたコークスをミルスケールと混合し、コークスのまわりにミルスケールを付着させる第一混合工程２００と、を備え、コークスは、粒径が１０〜３５ｍｍの小中塊コークスであり、第一混合工程２００の次工程として、ミルスケールが付着したコークスを焼結鉱と混合する第二混合工程３００をさらに備える。【選択図】図１ |
