小模块冷却壁是将性能优异的耐火材料直接浇铸在平行排列的冷却水管上而形成的一种新型冷却设备。采用ANSYS软件建立了小模块冷却壁温度场计算模型,利用该模型计算了炉气温度为1 200~1 600℃、冷却水流速为0.5~2.5m/s条件下壁体材质导热系数、水管材质、水管直径、水管间距、冷却水流速及工作环境温度等条件变化时小模块冷却壁的温度分布状况。结果表明,小模块冷却壁对炉气温度变化的适应能力较强,壁体材质导热系数、水管间距、壁体厚度对小模块冷却壁传热性能影响较大,而水管直径、水管材质及水流速的影响较小。
Small module cooling stave is a new type of cooling device formed by casting high-performance refractory materials directly on cooling pipes arranged in parallel. The calculation model of the temperature field of the small module cooling wall was established by ANSYS software. The thermal conductivity of the wall material was calculated using the model with the temperature of 1200 ~ 1600 ℃ and the cooling water flow rate of 0.5 ~ 2.5m / s, , Water pipe diameter, water pipe spacing, cooling water flow rate and working conditions such as temperature changes in the small module cooling wall temperature distribution. The results show that the small module cooling wall has strong adaptability to the temperature change of furnace gas, the thermal conductivity of the wall material, the spacing of the water pipe and the thickness of the wall greatly influence the heat transfer performance of the small module cooling wall, while the diameter of the water pipe, The effect of flow rate is small.
