摘要

The parameters of the cast structure in the columnar crystallization zone were investigated in a section perpendicular to the wide face of continuous cast slabs of varying thickness. The distribution of the main cast grain parameters across the thickness of continuous cast low-alloy steel slabs is presented. A method for evaluating the degree of the columnar structure development is proposed. It was found that the influence of steel overheating on the development of the columnar structure decreases as slab thickness increases.
