摘要 双辊铸轧过程中熔池内金属的流动状态及温度分布直接影响着铸轧过程的稳定性与铸带产品的质量。针对实验室双辊铸轧试验的特点,采用三维有限元法模拟了双辊铸轧过程的热流耦合问题,利用热平衡计算、铸轧实验和模拟相结合的反向方法分段建立了凝固过程中凝壳与铸辊之间热传导系数与铸轧速度、熔池位置之间的关系模型,并分析不同工艺条件下熔池内凝固变化的情况。 In a twin-roll strip casting process, the metal flow and temperature distribution in the molten pool have a direct influence on the stability of this process and quality of products. Aiming at the characteristic of casting process in the lab, using a 3D finite element analysis of the temperature field coupled with flow field, based on the heat balance calculation and using inverse methods between the simulations and real experiments, the models of the relationship among casting speed, location and coefficient of heat conduction between molten metal and roller in different section are given, and also the different freezing cases of different technological conditions in the molten pool are analyzed.
