摘　　要：采用焦炭反应炉对不同种焦炭进行反应性互补试验,得到混合焦炭失碳率和反应性的直线关系并结合粒度和位置影响,总结了在不同炉况条件下焦炭混合入炉的可行方法,提高了高炉内主体焦炭的抗压强度,从而有效保障料柱的透气性,为进一步提高煤比,降低焦比创造有利条件。By conducting reactive complementary experiments on different kinds of coke using coke reactor,the current study gets the linear relationships between carbon loss rate and reactiveness of mixed coke.Based on the effects of particle size and position,it summarizes the typical upper dispensing means in different furnace conditions,which can improve the compressive strength of body coke in blast furnace,ensure the permeability of stock column and also creates favorable conditions for raising coal ratio and reducing coke ratio.

关 键 词：焦炭 互补性 透气性 上部调剂
