Research on Optimization of Tundish Flow Distrbution

Abstract:

Research was made on the flow behavior of the 45t single strand tundish by means of water model. The model was 1:3 in size of the real tundish. Experiment conditions satisfied Froude number similarity. Minimum residence time distribution (RTD) curves were determined by pulse response. The proportion of the plug flow, mixed flow and dead volume were calculated. An optimized solution was made of a combination of turbulence inhibitor, dam and weir to decrease the dead volume (Vd) in the tundish to 11.36%, 67.8% lower than before. Production contrast tests showed that, with the optimized flow control solution, removal of oxide inclusion in slab is improved by 35.3%.
