Hydraulics Simulated Experimental Study on a Two Strand Tundish at Different Flow Rate

A 1∶2.5 hydraulics modle experiments were conducted to simulate a 72 t two- strand slab continuous casting tundish. The impact of using flow control devices and turbulence inhibitor on the flow field in tundish at different flow rate of flow had been investigated in order to gain the best combination of flow control devices in the inner cavity. The result shows that the best combination of flow control device includes 80 mm depth of weir,100 mm,height of dam,80 mm distance between weir and dam,as well as installation of turbulence inhibitor. When the flow flux are 1.63,2.00,2.57 and 3.00 (m³/ h),the shortest residence time increase by 13,7,22 and 13 seconds,and dead area ratio decreases by 3.5%,11.2%,9.1% and 13.8%,respectively.
