摘　　要：通过宽厚板坯连铸中间包水模实验,研究了不同控流装置对中间包内流动特性的影响。结果表明:带顶缘和不带顶缘的抑湍器均能明显提高活塞区的体积分数,且死区体积分数也有不同程度的降低;与带顶缘的抑湍器组合的中间包出口附近的挡坝设计参数对中间包内钢液的流动特性有影响;与带顶缘的抑湍器组合的墙坝间距有一个控制钢液流动特性的最佳值。通过实验研究,提出了优化的设计方案。A water model of a wide and thick slab continuous casting tundish was established to study the effect of different control devices on the characteristics of fluid flow. The results showed that the turbulence inhibitors with and without top extending lip both can improve obviously the plug flow volume and decrease the dead volume to some extent. The design parameters of the dam nearby the outlet combined with turbulence inhibitor with top extending lip have some effect on the fluid flow in tundish. And the distance between the weir and dam combined with turbulence inhibitor with top extending lip has an optimal value for the fluid flow. An optimal proposal is presented through an optimizing study by water modeling.
