摘要
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．结果表明，随中心矿焦比降低，能够形成充分发展的倒Ｖ型软熔带．总矿焦比增大时，软熔带顶点位置降低．喷煤比增大则中心软熔层位置逐渐升高，而鼓风富氧率升高时中心软熔层位置逐渐降低．中心加焦法是发展倒Ｖ型软熔带。
Discusses the shape and forming position of the cohesive zone in the blast furnace by means of dynamic hot model of three dimension. It is found that the perfect inverse Ⅴ type cohesive zone can be formed with the decrease of center ore/coke. When the total ore/coke increases,the cohesive zone top lowers,with the increasing of pulverized coal injection rate,the cohesive layer position at the center is gradually rised. While the raise of oxygensiched rate of blast,the cohesive layer position at the center is gradually decreased. The center coke charging method is a kind of effective measure to develop the inverse Ⅴ type cohesive zone,reduce the resistance of gas flow and increase blasting quantity.
