Resumen
Physical and mathematical modelling techniques were used to study the molten steel flow behaviour in a multi-strand bloom tundish. Three different cases were studied: a bare tundish (BT), a tundish equipped with two pairs of baffles and a waved impact pad (BWIP) and a tundish equipped with a turbulence inhibitor and a pair of dams (TI&D). Chemical mixing of tracer turbulence diffusion was also simulated and compared with experimental results. The TI&D arrangement showed a better tracer distribution among the outlets and an improvement of the fluid flow characteristics yielding lower values of back mixing flow and a good relation of mixed and plug volume flows. The mass transfer model coupled with the k-ε turbulence model predicted acceptably well the experimental chemical mixing of the tracer in the water model.
