A Novel Approach to Simulate and Evaluate Submerged-Entry Nozzle Clogging Evolution Using the Full-Scale Physical Twin of a Continuous Casting Mold

Submerged-entry nozzle (SEN) clogging during continuous casting is a well-known but not well-understood phenomenon that impacts steelmaking productivity and quality. Physical water modeling provides insight on mold flow, but prior studies including SEN clogging have used simplified approaches. The true shape of SEN clogging is complex, and its impact on mold flow may not be reflected during simulations. Additionally, SEN clogging formation is cumulative, but it can only be observed after the SEN’s removal from the caster. In this paper, realistically clogged SENs were replicated with enhancements and installed in a physical twin to study its impact on mold flow.
