Simulation on the Behavior of Argon Bubbles in Slab Continuous Casting Mold

Abstract

Aiming at the behavior of Argon Bubbles in Slab continuous casting mold with cast speed 1.7 m/min, the influence of blowing argon flow rate on bubble size, bubble distribution, the liquid surface level oscillation and behaviors of slag-melt were investigated by using water model and numerical simulation, the 190 mmx1900 mm slab mold is taken as an object of study. the results show that with increasing gas flow rate in nozzle the size of bubbles in mold increased, the bubble numbers near the narrow face of the mold decreased and most of the bubbles float upward to the surface of the mold in regions around the submerged entry nozzle. the emulsified slag entrapment, metal level bareness and slag entrapment near the nozzle were mainly caused by blowing gas flow rate.
