| 摘 要： | 基于边界条件替换方法建立了高炉冷却壁本体和捣打料与炉气之间的换热系数计算模型。用试验测量冷却壁近热面温度来推算冷却壁热面温度，与冷却壁温度场计算模型结合，确定了炉气温度在500~1 248 ℃范围内，高炉冷却壁与炉气之间的换热系数。结果表明，本模型的计算值与前苏联学者的试验结果吻合。

| Abstract: | A calculation model of the coefficient of heat transfer between gas and stave body and inlaid refractory is built based on the substitution method of boundary condition. The heat transfer coefficient at the gas temperature ranging from 500 ℃ to 1 248 ℃ between stave and furnace gas is determined by the combination of calculation model of temperature field and the temperature value of hot surface calculated from the temperature measured near hot surface. The results show that the calculated value of simulation model is coincident with the value measured by Russian. |
