摘　　要：高炉矿焦混装能提高冶炼强度,降低焦比,提高生产率:延长一代炉役的寿命。本文提出了高炉料柱散料体内煤气流动的附面层理论,导出了适用于高炉煤气运动的附面层微分方程式和积分方程式,对高炉内矿焦混装及层装煤气运动的附面层特性进行了细致分析。并对鞍钢10号高炉的矿焦混装工业试验进行了讨论。Mixed charging can increase the smelting intensity, productivity and compaign life of blast furnace and can decrease the coke rate. This paper puts forward the boundary theory of gas flow in furnace stack. The differential and integral equations suitable for the gas flow have been conducted. Detailed analysis on characteristics of boundary theory of the gas flow in the stacks of the mixed and layered chargings are carried out. The industrial test of the mixed charging on №. 10 BF at Anshan Iron & Steel Co.
