摘要/Abstract

摘要： 以能量平衡为基础，采用辐射段法模型建立了炉气段、炉围段和钢坯表面段的能量方程组，通过钢坯表面的热流与内部导热方程耦合求解，其中炉气和炉围的温度场采用主变量修正法求解，钢坯温度场采用隐式有限差分求解，与现场实测板坯温度对比验证模型的准确性，分析了上炉膛各段高度对钢坯温度场及排烟温度的影响. 结果表明，预热段高度在0.5~0.9 m，高度每增加0.2 m，钢坯出炉时上表面温度升高约2.8℃，排烟温度降低约10℃；加热一段高度在0.9~1.9 m，高度每增加0.2 m，钢坯出炉时上表面温度平均增加2.5℃，排烟温度平均降低8.5℃；加热二段和均热段高度变化对钢坯出炉时表面温度及排烟温度影响不大. 合理确定预热段和加热一段高度有利于钢坯加热并节省燃料消耗.
