Abstract
A process for thin strip production integrates continuous casting and rolling, with steps including continuous casting, rough rolling, induction heating, finish rolling, laminar cooling, high-speed shearing, and coiling. A key feature is the in-line heating between casting and rough rolling, where wide surfaces, narrow surfaces, and corners of the casting blank are heated simultaneously. This process improves rough rolling efficiency, enhances uniformity and thickness stability of thin strips, reduces out-of-tolerance rates, and minimizes rolling-induced cracks.
