Abstract：Optimization of flow control devices for fourstrand tundish in a steel plant was investigated by physical simulation. The optimization experiment was divided into the optimization of baffles type and the optimization of baffles structure. The experimental results showed that the flow state of the fluid in the prototype scheme was very poor, and the excessive diameter of the diversion orifice could easily lead to shortcircuit flow, and the proportion of dead zone was as high as 34.16%. The proportion of dead zone in the optimized scheme Y3 was decreased by 33.14%. The average residence time of the fluid was extended from 761.2 to 900.7 s, and the stagnation time was extended from 32.2 to 76.7 s. The optimization effect was remarkable. It showed that the optimum scheme could significantly improve the utilization ratio of ladle volume and the flow state of molten steel, which was conducive to the improvement of metallurgical quality.
