摘　　要：采用通用有限元软件ANSYS计算了300 m3高炉铸钢冷却壁的温度场和应力场,数值分析铸钢冷却壁冷却水管内径、间距、壁体厚度、镶砖厚度以及冷却水流速对冷却壁热面最高温度和热应力的影响。导出了高炉铸钢冷却壁的初步优化结果:冷却水管间距200 mm,水管内径20 mm,壁体厚度为180 mm,镶砖厚度为70 mm,与之相匹配的冷却水流速为2.0 m/s。The temperature and thermal stress fields of cast steel cooling stave are calculated by finite element method software ANSYS in blast furnace at Maanshan Iron and Steel Co. , Ltd. The influence of inner diameter, distance of water pipe, thickness of the cooling stave, thickness of cast-in brick in the cast steel cooling stave, and the speed of cooling water on maximum temperature and thermal stress of the stave hot face is discussed. The preliminary optimization results of cast steel stave show that the better value values of cooling channel interval, inner radius of water channel, thickness of the cooling stave body, thickness of cast-in brick and speed of cooling water are 200 mm, 20 mm, 180 mm, 70 mm and 2.0 m/s respectively.
