Description
Summary:The kinetics of the solid shell formation in a continuously cast ingot in a mold is studied under monotonic and pulsed-continuous cooling conditions. The slab shell growth rate is calculated for rail and graphitized steels under various cooling conditions. The structure formation in the solidifying metal is theoretically analyzed. During the course of cyclic cooling, transitions from a columnar to an equiaxed-grain structure and vice versa are likely to occur in the forming ingot shell. As a result, a disperse structure forms in the surface layer of the slab.
