摘    要:以宝钢-连铸板坯结晶器为研究对象,采用大型商业软件CFX4.3,将模拟计算出的浸入式水口的出口速度直接赋给结晶器作为入口条件,计算了结晶器内钢液的流动情况.结果表明:速度矢量在水口出口截面分布不均匀、方向与水口倾角不一致.因此,有必要将水口计算结果与结晶器模型结合起来以更好地反映钢液的流动情况.

关 键 词:结晶器  浸入式水口  流场  数值模拟

Abstract:The commercial code CFX4.3 was applied to simulate fluid flow in the mold of No.l continuous slab-casting machine in BaoSteel. The simulated velocity vector at the nozzle outlet ports was used as inlet boundary conditions of the mold. Results indicated that the velocity vector was not evenly distributed at the nozzle outlets and its direction may not be consistent with the ports. For this reason, it was necessary to connect the nozzle simulation results with the mold model to better reflect the real flow field.
Keywords:mold  submerged entry nozzle  flow field  numerical simulation
