Method for blowing coke breeze in blast furnace

The invention relates to a blast furnace coke breeze injection method, and belongs to the technical field of blast furnace burden. The method comprises the following steps: screening the coal coking by-product to separate out first coke breeze; performing first fine grinding treatment on the first coke breeze to obtain second coke breeze; the second coke breeze, bituminous coal and anthracite are subjected to second fine grinding treatment, and coke breeze mixed fuel is obtained; and spraying the coke breeze mixed fuel into a blast furnace. Through the method, the technical problem that coke breeze is not easy to burn in the prior art is solved. 本申请涉及一种高炉喷吹焦末的方法，属于高炉炉料技术领域。所述方法包括：对煤炭焦化副产物进行筛分处理，分离出第一焦末；对所述第一焦末进行第一细磨处理，得到第二焦末；对所述第二焦末、烟煤和无烟煤进行第二细磨处理，得到焦末混合燃料；将所述焦末混合燃料喷入高炉。通过该方法，以解决现有技术中焦末不易燃烧的技术问题。
