Abstract

Abstract: Three dimensional numerical simulation on steel works 200 mm x 1600 mm casting slab two-strand T- shape 23 t tundish 4 kinds of structure scheme-present baffle wall and dam, turbulence inhibitor and dam, turbulence inhibitor and present baffle, wall as well as new baffle has been carried out by using calculation fluid dynamics software FLUENT to study liquid flow characteristics of original tundish and with installed different flow control devices. Results show that in all design schemes the tundish with installed turbulence inhibitor and dam has best optimum effect; the volume fraction of dead zone in tundish decreases from 30. 18% to 16. 51% , the volume fraction ratio of piston flow zone and dead zone- R_vp/vd increases from 55. 80% to 129.44% , the flow in tundish is stable to be available for inclusions in liquid floating up.
