Effect of Nozzle Clogging on Surface Flow and Vortex Formation in the Continuous Casting Mold

摘要

Nozzle clogging induces asymmetric surface flow, causing vortex formation and inclusion defects. This work applies computational and experimental approaches. The resulting increase in the asymmetries of the surface flow velocities, velocity time variations and vortex occurrence frequency on opposite sides of the mold are quantified.
