摘　　要：钢液过热度是薄带铸轧工艺过程中的一个重要参数,它不仅影响钢液的流动性能,还影响凝壳厚度和Kiss点高度,使铸轧力发生变化,从而影响铸带的整体性能。利用有限元和实验相结合的方法确定了在浇注不锈钢时,过热度对熔池内钢液的温度场、速度场分布的影响,确定出了在指定工况下的最佳过热度范围。Liquid steel superheat, a significant parameter in the process of strip casting, influences not only the fluidity of liquid steel, but the thickness of solidification shell and the height of Kiss point as well, thus change rolling force and affect the combined performance of casting strip. The effect of superheat on the distribution of temperature field and velocity field of liquid steel in the molten pool was studied utilizing finite element mmethod and experiments, and the optimal range of superheat at specific working condition is determined.
