Realization of Endless Hot Strip Rolling Yasuo Ichii, Takahiro Yamasaki, Shoji Murayama |
| Synopsis: Kawasaki Steel was the first in the world to start the so-called "endless hot strip rolling" at the No. 3 Hot Strip Mill in Chiba Works by realizing hot sheet bar joining and continuous finishing rolling in 1996. In order to realize hot endless rolling, highly accurate process control and full automation with high reliability are necessary and Kawasaki Steel developed central control technologies for this process including mill pacing control, flying joining control, finishing mill joint stabilization, flying gauge change control and fully automatic high-speed shear and coiler control. With these new technologies, the stable endless hot strip rolling process has been made possible and the quality of products has been improved. As a result, it has become possible to produce thin-wide strips and ultra-thin strips exceeding past rolling limits and in addition, to develop and produce new products making use of lubricated rolling and/or force-cooled rolling. |
