A rolling method in which the rolled pieces alternately travel back and forth between different pass types in the same stand or on different stands in the same row. This rolling method is widely used in horizontal rolling mills such as blooming mills, blanking mills, rail beam rolling mills, and large and medium-sized steel rolling mills. Shuttle rolling is also commonly used when producing round steel and square steel with a diameter (or side length) greater than 20mm on a small horizontal rolling mill. Shuttle rolling is a traditional rolling method. Its advantages are: simple equipment and low cost; flexible production and strong adaptability, suitable for multi-variety and small batch production; tension-free rolling, suitable for complex production sections product; simple to operate and easy to adjust. The disadvantages are: the gap time between each pass is long and the productivity is low; the length of the rolled piece and the weight of the wire rod are limited; it is not convenient to realize automation.
