Technical Field

[0001] The utility model relates to the technical field of steel material processing, in particular to a high-efficiency steel material rolling and straightening device. Background Art

[0002] During the rolling process of steel, due to the influence of equipment accuracy, material properties or other factors, the rolled steel may be bent or twisted. At this time, it is necessary to apply a certain amount of force and control to restore these deformed steels to a state close to the ideal straight line to meet the requirements of subsequent processing or use. This is the process of rolling and straightening steel. The rolling and straightening process is of great significance for improving the quality of steel, reducing the scrap rate and improving production efficiency. Through rolling and straightening, the straightness and surface quality of the steel can be ensured to meet the strict requirements of various industrial applications.

[0003] However, some steel rolling and straightening devices currently on the market can only perform rolling and straightening operations on steel of fixed thickness. When steel of different thicknesses needs to be straightened, the main part of the equipment needs to be disassembled and reassembled, which is inconvenient, time-consuming and labor-intensive to operate, and has low work efficiency, which is not conducive to diversified production needs. Therefore, an efficient steel rolling and straightening device is proposed. Utility Model Content
