高炉软熔带形态变化的物理模拟

利用三维动态热模型探讨了高炉内软熔带的形态及形成位置。实验结果表明，随中心矿焦比降低，软熔带形状由Ｗ型向倒Ｖ型转变。当采用中心加焦布料方式时能形成充分发展的倒Ｖ型软熔带。总矿焦比增加时，软熔带顶点降低，根部升高，形状度Ｉ增大，无因次高度ｈ顶减少，料柱阻力增加。

Physical Simulation on Change of the Cohesive Zone shape in the Blast Furnace

This paper discussed the shape and forming position of the cohesive zone in the Blast Furnace by suing the dynamic hot model of three-dimension.Experiment results show that the shape of the cohesive zone changes from W type to inverse V type with the decrease of center O/C.When the Center Coke Charging Method is applied,the perfect inverse V type cohesive zone can be formed.With the increase of total ore/coke,the cohesive zone top lowers,the bottom rises,the form index (I)increases,the free factor height decreases,and the resistance of burden increases.
