NON-ISOTHERMAL FLUID FLOW IN A CONTINUOUS CASTING TUNDISH

Temperature variation phenomena observed inside the metallurgical tundish in the continuous casting is principally due to several factors, high temperature of the ladle metal jet, important thermal losses, heat transfer between molten steel and tundish walls and more still, in contact with the slag layer at bath surface and if necessary cooling or warming in refining composition operations. A numerical simulation using the CFD code "Fluent" is realised. Investigation of heat transfer-which has a great importance in the natural convection and the inclusions floating at slag surface-, is proposed. Results are presented for three arrangements of the tundish, where the interest and role of the control devices is improved
