[0002] In the traditional steel bar production process, the rolling process is usually divided into two stages: rough rolling and finish rolling. The main purpose of the rough rolling stage is to initially roll the steel bar to a size close to the finished product, while the finish rolling stage focuses on forming the required rib structure on the surface of the steel bar to enhance the bond between the steel bar and the concrete. However, the rolling mills in the existing technology mostly use single or dual motor drive, and in the finish rolling stage, the steel bar is often in a passive pulling state, which not only limits the rolling efficiency, but may also cause uneven force on the steel bar, affecting product quality and production safety.
