Abstract Based on the control-volume method a 3-D comprehensively coupled model has been developed for binary iron-carbon to describe the turbulent fluid flow, heat transfer, solidification, and solute redistribution in the thin slab continuous casting process. The calculated results show that the turbulent fluid flow dramatically alters the shape of the isotherms and the distribution of the solute in the thin slab. The thickness of solidified shell is uneven along broad face because of the flow jet. The formation mechanism of macrosegregation is investigated and the possible position of the macrosegregation is analyzed.
