摘　　要：以国内某企业六流中间包为研究对象,利用数值模拟与物理模拟相结合的方法,对中间包内温度场、流场及中间包内衬的冲蚀效果进行系统的分析。计算结果表明,改变中间包内的控流装置可以有效改善钢液的流动情况,使中间包内各个出口的温度差减小,延长钢液在中间包内的停留时间,降低钢液对中间包内衬的冲蚀强度,延长中间包使用寿命。By taking a six-strand tundish in a certain company as the research subject, the temperature field and flow field, and erosion of refractory materials of tundish were systematically analyzed by combi- nation of numerical simulation and physical simulation. The calculation results show that changing the flow control devices in the tundish can effectively improve the flow of liquid steel, decrease temperature differential among all the tundish outlets, prolong the residence time of molten steel in the tundish, and reduce the erosion intensity of liquid steel on the refractory materials of the tundish , and thus extend the service life of tundish.
