采用有限元软件ANSYS建立高炉冷却壁稳态传热模型,利用ANSYS单元生死技术模拟冷却壁表面渣皮熔化行为,以计算铸铁冷却壁在渣皮稳定、渣皮脱落、冷却壁烧损和冷却壁烧毁4种工况下的温度分布和热负荷。分析结果表明,冷却壁热负荷随着炉气温度的升高而增加,提高冷却水速度和壁体烧损变薄对热负荷的影响较小。渣皮脱落和冷却壁完全消失造成热负荷急剧增加。 The finite element software ANSYS was used to establish the steady heat transfer model of blast furnace stave. The melting behavior of slag skins was simulated by the life and death technique of ANSYS unit to calculate the effect of cast iron stave on slag skull stability, slag skull loss, Burned 4 kinds of conditions of temperature distribution and heat load. The results show that the thermal load of the cooling wall increases with the temperature of the furnace gas, and the effect of increasing the cooling water velocity and thinning of the wall on the thermal load is small. The skull sheds and the cooling wall disappear completely and the heat load increases sharply.
