Abstract：Main equipment and key technology of Bengang thin slab continuous casting and rolling line, including FGC (Fly Gauge Change) technology, automatic minimum tension control and looper control technology, and major equipment and function of semiendless coiling operation and so on, were analyzed. Semiendless rolling made it possible to improve gauge accuracy and flatness over the full length of the strip. Production of ultra-thin hot rolled strip and high-formability steel strip have become possible with semiendless rolling technology.
