| Abstract |
Hydrodynamic approaches are developed to find optimum operational conditions of rectangular continuous casting tundishes thorough application of water model experiments and three-dimensional computer simulations. Water model experiments via volume analysis in a continuously flowing vessel are made for various physical flow control devices such as ladle submerged nozzle, weir and dam. RTD curves are obtained by means of conductivity method. The three-dimensional computer simulations are compared with the above experimental results. The three-dimensional computer simulations are compared with the above experimental results. It is found that the weir and the dam can play an important role in obtaining desirable flow patterns; they efficiently increase the minimum retention time, plug flow volume ratio and the mean residence time, and confine the turbulent mixing effect near fluid inlet regions. Tracer dispersion patterns simulating turbulent mixing effects show good agreement between the experiments and computed results. The present results could be used as basic data for designing a new tundish system in a real steel processing. |
