根据宝钢３号高炉（３ＢＦ）冷却壁纯水密闭循环系统的特点，采用超声波测量仪测量冷却壁的水流量，用数字测温仪和红外线测温仪测量冷却水的温差，取得了大量的冷却壁热负荷数据。对３ＢＦ各段冷却壁的热负荷分布进行了分析，并研究了冷却壁破损原因及对策，为３ＢＦ冷却壁热负荷的管理和降低燃料比提供了科学依据 According to the characteristics of closed circuit of pure water in BF 3 BF of Baosteel, the water flow of the cooling wall was measured by ultrasonic measuring instrument, the temperature difference of cooling water was measured by digital thermometer and infrared thermometer, and a great deal of cooling was achieved Wall heat load data. The heat load distribution of each section of BF3F was analyzed and the causes and countermeasures of the cooling wall were researched, which provided a scientific basis for the management of the thermal load of 3BF cooling wall and the reduction of fuel ratio
