Research on Numerical Simulation Study of Solidification Heat Transfer Coefficient of Extra-Wide Slab

Abstract

Because the extra-wide slab continuous caster has larger sectional width, heat emission condition is different between the length and width. Therefore, it is inevitable that the water distribution is regional separation along the casting slab width and length. It brings a lot of difficulties to determine process parameters and control continuous casting process, and causes quality defect. Based on 3250 mm × 150 mm extra-wide slab casting and production process, the paper established the finite element model, calculates the temperature distribution and shell thickness of the slab with different casting speed and superheat, to study influence of process control parameters of wide slab quality.
