Influence of the Reduction in the First Matched Groove Pair of a Three-High Stand on Billet Damage
The influence of the one-time reduction in the first pair of matched grooves in a three-high stand on the cracking at the end of the billet is simulated. The traditional six-pass procedure in the three-high stand is compared with the new six-pass procedure and the eight-pass procedure proposed in th...

| description | The influence of the one-time reduction in the first pair of matched grooves in a three-high stand on the cracking at the end of the billet is simulated. The traditional six-pass procedure in the three-high stand is compared with the new six-pass procedure and the eight-pass procedure proposed in the present work. The comparison shows that, by milder reduction in the first pair of matched grooves, the effective stress may be decreased, along with the likelihood of cracking at the end of the billet. The damage at the ends of the multiple billets in the three-high roughing stand may be minimized by means of further decrease in deformation in the first passes on rolling multiple continuous-cast billets made of high-quality structural steel, along with decrease in the initial rolling temperature and division of the billet into measured lengths on a band saw. |
