Synopsis : The traverse gage profile and the flatness of hot-rolled strip are important quality requirements reflecting users' demands growing ever more severe. The hot strip mill with a high capacity for profile control is required to consistently produce hot-rolled strip of good profile and flatness. Also, to guarantee the flatness of finished products, control at finishing mill alone is not sufficient and must cover the cooling process as well. Kawasaki Steel recently established a hot strip mill rolling technology that assures excellent profile and flatness by installing a tapered-crown work-roll shifting mill (K-WRS mill), the company's own development, and HC (high crown control) mill at hot strip mills of Chiba and Mizushima Works respectively and by extending the flatness control process down to the cooling stage on the runout table. The paper outlines the technology, focusing on the results of operations. |
