2019年以来长钢8号9号高炉经过提高负荷攻关活动，高炉焦炭负荷由4.3提高到4.9，燃料成本扭亏为赢。其提高焦炭负荷的主要措施有：精料、提高热风温度、中心加焦、提高富氧率、搞好上下部调剂，稳定炉况和加强管理，推行标准化操作等。
Since 2019, the coke load of No. 8 - 9 BF of Changgang was increased from 4.3 to 4.9 after the load improvement, and the fuel cost turned to win. The main measures to improve coke load include: fine material, raising hot air temperature, coke adding in center, increasing oxygen enrichment rate, adjusting the upper and lower parts, stabilizing furnace condition, strengthening management, and carrying out standardized operation.
