摘　　要：根据首钢4号高炉风口焦炭取样的数据,分析了回旋区焦炭带的长度与实际风速、风口焦炭粒度及焦炭质量的关系,探讨了煤比与渣量及回旋区焦炭带的长度的关系;探索了高炉透气性指数与实际风速、煤比、风口焦炭粒度及高炉布料制度之间的关系。通过对炉缸径向煤气压差分析对高炉焦炭负荷、上下部制度的合理调整提出了建议。相关建议实施后,高炉技术经济指标明显改善。Based on data of tuyere coke sampling at No. 4 BF of Shougang, the relationship between coke zone length in raceway and actual wind velocity, coke size and quality is analyzed, the relationship between coal ratio, slag volume and coke zone length in raceway is discussed and the relationship between the permeability index and actual wind velocity, coal rate, tuyem coke zone and charging regime is researched. Suggestions for adjusting the ratio of ore to coke, upper and lower regimes are given through analyzing gas pressure difference in hearth radial direction. Thanks to implementing the suggestions, technical and economic indexes of the blast furnaces have been obviously improved.
