Modeling 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 کاملInclusion Removal by Bubble Flotation in a Continuous Casting Mold
Fundamentally based computational models are developed and applied to quantify the removal of inclusions by bubbles during the continuous casting of steel. First, the attachment probability of inclusions on a bubble surface is investigated based on fundamental fluid flow simulations, incorporating the turbulent inclusion trajectory and sliding time of each individual inclusion along the bubble ...
متن کاملInterfacial Friction-Related Phenomena in Continuous Casting with Mold Slags
Many phenomena in continuous casting including the formation of surface defects are greatly affected by heat transfer in the mold. The interfacial slag layers between the solidifying steel shell and the mold wall dominates the resistance to heat removal and thus controls mold heat transfer. Surface defects, such as longitudinal cracks and star cracks have been associated with variation of slag ...

متن کاملApplication of fuzzy logic control for continuous casting mold level control
This paper deals with the problem of molten metal level control in continuous casting. Under normal circumstances, proportional integral derivative (PID) control performs quite well, but abnormal conditions (in particular nozzle clogging/unclogging) require manual intervention. Indeed, when the flow of matter into the mold increases suddenly, the PID controller is not always able to prevent lar...
