中间包内流体流动状态对铸坯质量的优劣起着至关重要的作用。采用合理的控流装置可以优化钢液在中间包内的流动特征,本文通过实验室物理模拟实验与数值计算相结合的方法,分析比较了两种导流隔墙对四流连铸中间包内流体流动特征的影响。物理模拟和数学计算结果能够较好地吻合,结果表明:与直板挡墙中间包相比,V型导流隔墙的使用将中间包死区体积分率降低了45%,各出水口之间响应时间和峰值时间之间的标准差有所减小,均匀了各水口之间的流动状态。
The fluid flow in the tundish plays an important role on the quality of the billet. A reasonable flow control device can be used to optimize the flow characteristics of molten steel in the tundish.Through the combination of laboratory physical simulation and numerical calculation, Effects of fluid flow characteristics. The results of physical simulation and mathematical calculation agree well with each other. The results show that the use of V-shaped guide wall reduces the volume fraction of dead zone in the tundish by 45% compared with the straight wall tundish, The standard deviation between the response time and the peak time is reduced and the flow between the nozzles is even.
