Abstract

This paper presents a thorough review of the literature on defects in beam blanks, focusing on formation mechanism and the solutions proposed to decrease their occurrence. The review includes the techniques used to investigate the defects. The measures taken have to do with changes in liquid steel preparation, in the casting system, mold design, secondary cooling modifications and regulation, strand support, machine alignment, and more.
