摘要
针对某厂六流特殊非对称型中间包温降严重的特点,采用耦合数值求解方法,计算并优化了中间包内的流场与温度场。结果表明:这种特殊中间包在未设控流装置时,入口与近端出口短路流严重,近端出口与远端出口的温差最大为8℃;优化后的中间包结构消除了短路流,均匀了各流钢液温度,最大温差降低到3.3℃,优化后的中间包能更好地满足生产的需求。
The method of coupled numerical was taken on the heavily temperature dropping of six - strand special unsymmetrical tundish . The flow field and temperature field in the tundish were calculated and optimized . The result show that when the special tundish was used without any flow control devices, it had a very short flow route between entry and near outlet, the biggest temperature difference between near outlet and far outlet is 8 ℃ ;The optimized tundish avoid the short flow route and uniform the molten steel temperature of each nozzle, and the biggest temperature difference reduced to 3,3 ℃. It is better than the original one and meet the requirement of actual operations.
