中文摘要	采用场协同理论分析了连铸中间包内钢液流场与温度分布之间的关系,并对钢厂六流中间包进行了数值模拟计算。结果表明,当中间包不采用控流装置时,大部分区域钢液流场与温度梯度场协同性好,钢液温度梯度大,最大温差达27 K,出口最大温差达3 K,(火积)耗散值大,各出口RTD(停留时间分布)曲线相差较大;当中间包内设置斜孔挡墙后,钢液流场与温度梯度场间的协同程度降低,钢液温度分布较均匀,最大温差为12 K,各出口最大温差仅为0.3 K,(火积)耗散值降低了57.6%,各出口RTD曲线近似。; The relation between distribution of temperature and fluid flow field in tundish for concasting has been analyzed by using theory of field synergy and the distribution of temperature and fluid flow field in a tundish for six strands at a steel works was simulated and numerically calculated.Results showed that as tundish without flow control devices,the synergy between temperature gradient field and fluid flow field was better,the temperature gradient of liquid steel was great i.e.the max temperature differential-27 K and the max temperature differential at outlet-3 K with large entrancy dissipation value and large difference between curves of residence time distribution at outlet;as tundish with baffles,the degree of synergy between temperature gradient field and fluid flow field decreased,the distribution of liquid steel was even i.e.the max temperature differential-12 K and the max temperature differential at outlet-only 0.3 K,the value of entrancy dissipation decreased by 57.6%and the curves of residence time distribution at outlet were similar.; 国家科技攻关计划项目资助(2005BA325C); 973计划前期研究专项资助(2009CB626605)
