焦炭作为料柱的骨架,随着高炉的大型化以及喷煤比的提高,焦炭的作用显得更为重要,近年来随着工艺设备不断更新,新建高炉逐渐大型化以及采用炼铁新技术,使高炉的焦比不断降低,由于焦比降低、煤比不断提高,高炉的透气性和透液性变差,因此焦炭质量的好坏显得尤为重要。 Coke as the skeleton of the column, with the large-scale blast furnace and coal injection ratio, the role of coke is even more important in recent years with the continuous upgrading of process equipment, the new blast furnace gradually large and the use of new ironmaking technology, The coke ratio of the blast furnace continues to decrease. As the coke ratio decreases and the coal ratio increases continuously, the permeability and liquid permeability of the blast furnace deteriorate. Therefore, the quality of the coke becomes more and more important.
