Abstract

Mold level fluctuations caused by unsteady bulging of the solidifying shell affect the quality of the steel and stable operation of the continuous steel casting process. A dynamic bulging model, which captures the behavior of the 2-D longitudinal domain through interpolation of multiple 1-D moving slices, is used to calculate the transient bulging profile, volume changes caused by unsteady bulging, and the accompanying level fluctuations in the mold. The liquid steel flow rate through the SEN into the tundish is calculated with a stopper-position-based model. These two models are combined to investigate mold level fluctuations in a thin-slab caster under real casting conditions. The model is verified by comparing the simulation results with transient measurements in a commercial thin-slab caster.
