摘　　要：三钢5号高炉有效容积为1250 m^(3),设有2个出铁口,20个风口,于2018年11月19日第二代炉龄开炉。2021年年底因原燃料质量变差后,高炉的稳定性变差,频繁出现塌料、悬料、管道等现象,甚至多次出现炉凉现象。通过改善原燃料质量、调整上部装料制度和下部送风制度、采用蛇纹石洗炉、加强日常操作管理等措施,高运顺行状况明显改善,各项经济技术指标稳步提升。Sansteel No.5 blast furnace which was opened on November 19,2018 has effective volume of 1250 m^(3),with 2 iron outlet and 20 tuyere.By the end of 2021.Due to the deterioration of the quality of the raw fuel,the stability of the blast furnace becomes worse,the phenolmena of collapse,hanging and pipeline frequently occur,and even the phenomenon of furnace cooling occurs many times.Through improving the quality of raw fuel,adjus-ting the upper loading system and the air supply system,using serpentine furnace washing,strengthening the daily operation management and other measures,the running condition of blast furnace is improved obviously,and the economic and technical indexes are improved steadily.
