Abstract

Effects of stopper rod movement on transient flow phenomena in the mold and formation of sliver defects are investigated via plant measurements and numerical simulations. First, sliver locations are correlated with stopper rod position and level fluctuation histories in the mold by analyzing images of slivers and process data recorded at ArcelorMittal Dofasco's No.1 Continuous Caster. Then, 3D transient CFD models are developed, validated with plant measurements, and applied to simulate transient flow, particle motion, and entrapment phenomena to reveal how level fluctuations arise, and how the slivers may have formed.
