【摘要】 本研究选用与铁矿石软熔性能相似的模拟物料在动态热模型中研究软熔带的形成过程及其对煤气流分布和传热的影响,以探索高炉软熔带的规律。通过建立的流体流动-综合传热模型,在“银河”计算机上所进行的数值解析,得到了气流在料层中的流函数、速度矢量、压力以及气体和固体温度的分布等。热态试验和数模计算结果与鞍钢7号高炉活体测定数据相一致。更多还原

【Abstract】 In order to search the rules of cohesive zone formation in blast furnace, and its influence ondistribution of gas flow and heat transfer, a dynamic thermal model using materials, similar to theiron ores in cohesive properties, was used in experiment. With the aid of proposed mathematical model of the fluid flow and combined heat transfer thenumerical calculaiton was carried out on the "Milk Way" computer. The flow function in burdenbed, the velocity component vectors, pressure of gas flow and the temperature distribution of thegas and solid burden have been obtained. The results obtained from dynamic thermal model, numer-ical calculation and practice are in good agreement.更多还原
