摘要： 以直径600 mm、辊宽550 mm的双辊薄带连铸的布流系统及熔池为研究对象，采用FLUENT软件对熔池内钢液流动进行三维非稳态数值模拟分析，以计算结果验证设计结构的合理性，分析转速及浇注温度对熔池内流场及温度场分布的影响. 结果表明，三维数值模拟能计算熔池沿轴向的温度场和凝固区分布，比二维数值模拟能更准确描述熔池的传热过程. 转速为60 m/min、浇注温度1490℃时，熔池温度场及凝固区分布最合理.

Abstract: The numerical simulation software FLUENT was used to analyze the three-dimensional unsteady conservation equations for transport phenomena in the flow distribution system and pool region of twin-roll with 600 mm in diameter and 550 mm in width in thin strip casting process. The rationalization of structure design was validated through the simulation results, and the influences of rotational speed and pouring temperature on the flow field and temperature distribution were analyzed. The results show that three-dimensional numerical simulation is more accurate in description of temperature distribution and solidification region along the axial direction of rollers than two-dimensional simulation. Moreover the temperature distribution and the solidification zone of molten pool are more reasonable when the rotational speed is 60 m/min, and pouring temperature 1490℃.

Key words: twin-roll thin strip casting, flow distribution system, three-dimensional numerical simulation, molten pool, nozzle
