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 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...

متن کاملAdaptive Mold Level Control in a Continuous Steel Slab Casting Process
Surface quality of the steel slabs in a Continuous Casting (C.C.) process is mainly determined by the stability of the Mold Level Control (MLC). Excessive mold level fluctuations lead to an additional machine scarfing process which is applied to the slabs to avoid surface defects. A conventional Proportional-Integral-Derivative (PID) controller is not robust enough to deal with the disturbances...
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...
