在扔过程的成双转动的长带，在熔融的水池的金属流动和温度分发直接影响这个过程的稳定性和产品的质量。在这篇论文， 3D 联合了热流动的 fenite 元素建模(女性) 为成双转动的长带扔不锈钢的模拟被执行。流的温度和扔的速度在温度地的影响从数字模拟被获得。溶质微分离在长带期间，扔不锈钢的过程也被模仿。一个 developedmicro 分离模型被用来计算在不锈钢的成双转动的扔的溶质微分离。在团结和温度的部分被给的在先令之间的关系，被用来决定 LIT，液体透不过的温度) ， ZST (零力量温度) 和在非平衡团结的时期的 ZDT (零韧性温度) 。温度在上的效果微分离被讨论。根据计算结果，在不锈钢扔的成双转动的长带的团结结束温度然后被决定，它能为控制团结结束温度的地点并且分析扔的长带的裂缝提供一个基础。

英文摘要：

In twin-roll strip casting process, metal flow and temperature distribution in the molten pool directly affect the stability of the process and the quality of products. In this paper, a 3D coupled thermal-flow fenite element modeling （FEM） simulation for twin-roll strip casting of stainless steel was performed. Influences of the pouring temperature and casting speed on the temperature fields were obtained from the numerical simulation. The micro-segregation of the solutes during the strip casting process of stainless steel was also simulated. A developed micro-segregation model was used to calculate the micro-segregation of solutes in twin-roll casting of stainless steel. The relationship between the solidus fraction in solidification and temperature was given, which was used to determine the LIT （liquid impermeable temperature）, ZST （zero strength temperature） and ZDT （zero ductility temperature） in the period of non-equilibrium solidification. The effect of temperature on the micro-segregation was discussed. According to the computational results, the solidification completion temperature in the twin-roll strip casting of stainless steel was then determined, which can provide a basis for controlling the location of solidification completion temperature and analysing the crack of the casting strip.
