The Role of Mold Electromagnetic Stirring in the Dissipation of Superheat during the Continuous Casting of Billets

A two-phase solidification model coupling mold electromagnetic stirring (M-EMS) is used to investigate the initial in region of billet continuous casting. One novelty this numerical study quantify how M-EMS induces primary and secondary flows, interacting with jet flows coming from submerged entry nozzle, those further influence dissipation superheat solidification. The role speeding up region, known previous studies casting practices, quantitatively verified. Additionally, some new knowledge regarding found. total heat transfer rate strand surface water-cooled copper not affected by M-EMS; M-EMS, effect on solid growth can only be detected out-of-the-mold while shell inside quite independent superheat; a strong tends accelerate but delays its cooling zones. aforementioned findings may valid for case current casting, confirmed other formats/parameters.
