摘要: 建立了80 t钢包有限元传热模型,运用ANSYS软件计算了不同条件的钢包稳态温度场,得出钢包各层都达到热饱和的温度场分布云图和包壁外表面温度分布曲线;分析了钢包壁、包底、覆盖剂材质及厚度对热损失的影响。结果表明:钢包的热损失主要是通过包壁,绝热层的导热系数宜低于0.10 W/(m·℃);覆盖剂厚度为40 mm左右,导热系数以小于0.05 W/(m·℃)为宜。

Abstract: A finite element thermal-conducting model of 80 t ladle has been established and stable state temperature  field of the ladle with different conditions was calculated by means of software ANSYS to get distribution cloud pattern of temperature  as  each  layer  of ladle being up to heat  saturation  and  outside  surface temperature  distribution  curves  of ladle wall. As well as the effect of materials and thickness of ladle wall,bottom and shielding agent on heat loss was analyzed.  Results showed that the heat loss of ladle was mainly through wall of ladle and the thermal conductivity of adiabatic layer  should  less  than  0.10  W/(m · ℃),and  as  shielding  agent  thickness  was  about  40  mm,the  thermal  conductivity  should  be controlled    below    0.05W/(m · ℃).
