Investigation of Fluid Flow and Heat Transfer in a Continuous Casting Tundish with Channel Type Induction Heating Using Mathematical Modeling and Water Modeling
The fluid flow and heat transfer in the tundish with the channel type induction heating was investigated with a 0.33-scale water modeling and mathematical modeling.Water modeling was used to measure residence time and fluid flow pattern.In the mathematical modeling,the induced joule heat,the electro-magnetic forces (EMFs) distribution and the heat transfer of the molten steel were calculated.The results indicate that the residence time of the molten steel in the tundish with heating is much longer than those without heating.It is mainly because the upward flow under the effect of buoyancy force which prolongs the molten steel motion path.The thermal loss of molten steel in the tundish can be compensated effectively by the induction heating.In addition,the movement of the molten steel was dominated under the combined effect of the thermal buoyancy and the EMFs.
