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1200～1600℃、冷却水流速为0．5～2．5 m／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。
The miniature modular cooling stave which is produced by casting unshaped refractories onto parallel ar-ranged cooling water pipes is a new kind of cooling equipment used in blast furnace.The temperature field calculat-ing model of the miniature modular cooling stave was established based on ANSYS and by using this model,the temperature field of the miniature modular cooling stave was calculated under different working condition of gas tem-perature 1 200-1 600 ℃ and water velocity 0.5-2.5 m/s when thermal conductivity of stave body,the water pipe ma-terial,the diameter of water pipe,the water pipe spacing,the stave thickness,the cooling water velocity and fur-nace temperature varied.The result shows that the miniature modular cooling stave can work safely under different furnace temperatures;the thermal conductivity of stave body,the water pipe spacing and stave thickness have a rel-atively great influence on the heat transfer performance of miniature modular cooling stave while the influence of wa-ter pipe material,the diameter of water pipe and water velocity is limited.
