Physical Modeling of Steel Delivery during Thin Slab Continuous Casting
A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...

متن کاملTurbulent Flow and Particle Motion in Continuous Slab-Casting Molds
Turbulent flow in the continuous casting process involves transient phenomena and the transport of inclusion particles and plays an important role in the quality of the steel. As shown in Fig. 1, the molten steel jet entering the mold may carry inclusion particles (e.g. alumina) and argon bubbles. Liquid flux can also be entrained from the shear of the liquid flow across the top surface and for...
متن کاملTransient Fluid-Flow Phenomena in the Continuous Steel-Slab Casting Mold and Defect Formation
Phenomena associated with the turbulent flow of molten steel in a continuous casting mold are responsible for many defects in the final product, including surface slivers, frozen meniscus hooks, captured inclusions that enter the mold from upstream, and mold slag entrapment. Animations of some of these transient flow phenomena are presented from Large-Eddy Simulations of a typical slab caster w...
متن کاملReview Article on Physical and Numerical Modelling of Sen and Mould for Continuous Slab Casting
Over the years, considerable efforts have been made to study the performance of Submerged Entry Nozzle (SEN) and mould of continuous slab caster. Numerous physical and numerical modelling studies have already been carried out and reported in the literature to study the fluid flow behaviour inside the mould. Based on the extensive literature search, a summary of these is presented here. For the ...
