摘要
通过高炉气体力学模型试验和水电比拟法测定,得到了宝钢高炉炉墙结厚度与气体和炉渣流速之间关系。开发了高炉流场模拟数学模型,并应用该模型从整个高炉的角度探讨了炉墙结厚对气体和炉渣流动的影响;模型研究的结果对炉墙结厚所引起的高炉“上热下凉”现象作出了解释,为制定合理的操作制度,消除结厚,纠正煤气流分布失常提供了理论依据。
The relationship between the extent of scaffolding and the flow rate distribution of gas and molten slag was found out by the experiments of the blast furnace gas dynamics model and the measurements of the water-electricity analogue approach. A mathematical simulation model of blast furnace flow fields has been developed and applied to the exploration of the influences of scaffolding on gas and liquid flows . The results obtained from the models study have given a reasonable explanation for the 'Hot-upper and Cool-lower' phenomenon caused by scaffolds.
