Numerical and Physical Study on New Tundish Designs to Produce a Swirling Flow in the SEN during Continuous Casting of Steel
New tundish designs with the aim to produce a swirling flow in SEN were investigated by both water model experiments and numerical simulations.The RSM(Reynolds Stress Model)model combined with the Stress-Omega sub-model was used to solve the flow field in new setups.Firstly,the numerical model was validated by water model experiment for a cylindrical tundish design.The results show that the simulation results agree well with the water model experiment results.A strong swirling flow in the SEN of the new tundish was successfully obtained.Specifically,the tangential velocity in the SEN could reach a value of around 3.1 m/s.The near-wall region has a high pressure which is in the range of around 20000 to 40000 Pa larger than the atmospheric pressure due to the centrifugal effect in the swirling flow.Then,the RSM model was used to investigate the swirling flow in a conventional tundish by simply put a cylinder in the tundish.The results show that a good swirling flow is obtained.The tangential velocity can reach around 2.1m/s at the location near the SEN outlet.
