Transient 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 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 کاملModeling of Continuous-Casting Defects Related to Mold Fluid Flow
The quality of continuous-cast steel is greatly influenced by fluid flow in the mold, particularly at the meniscus. Recent examples of computational model applications at the University of Illinois are presented to investigate the formation of several different types of defects related to flow phenomena. The amount of gas injection into the tundish nozzle to avoid air aspiration is quantified b...

15 صفحه اولEffect of Electromagnetic Ruler Braking (EMBr) on Transient Turbulent Flow in Continuous Slab Casting using Large Eddy Simulations
Static electromagnetic braking (EMBr) fields affect greatly the turbulent flow pattern in steel continuous casting, which leads to potential benefits such as decreasing flow instability, surface defects, and inclusion entrapment if applied correctly. To gain a fundamental understanding of how EMBr affects transient turbulent flow, the current work applies large eddy simulations (LES) to investi...
