A mathematical modeling study was carried out to examine the shrinkage of 250 mm-thick continuously cast slabs in the secondary cooling zone of a continuous casting machine (CCM), depending on casting speed, cooling mode, and carbon concentration. It was shown that slab thickness most closely matches roller spacing at the beginning of the secondary cooling zone hydroficated section, in contrast to the areas under the mold and at the continuous caster’ end. To more accurately match slab thickness and roller spacing, it is necessary to account for the shrinkage nonlinear nature, especially at the continuous caster’ end. Carbon concentration has a greater impact on shrinkage than casting speed. Cooling modes in the secondary cooling zone have little effect on shrinkage.
Chuev et al. (Mon,) studied this question.
