The tensioning and straightening machine is one of the indispensable and key process equipment widely used in modern continuous casting production lines, which mainly consists of two core structural parts, including the tensioning and straightening machine base and the tensioning and straightening machine body. As the fundamental supporting component, the tensioning and straightening machine base features high structural rigidity and stable load-bearing performance, which can effectively fix the overall equipment position, buffer the mechanical vibration generated during continuous operation, and ensure the overall structural stability of the equipment under long-term and high-load working conditions. The tensioning and straightening machine body is the core functional execution unit of the entire equipment, undertaking all core actions of material conveying, tension adjusting and shape correction in the production process. This professional process equipment is specially designed and matched for the arc-shaped continuous casting machine in the metallurgical casting industry. It mainly realizes the continuous and stable direct pulling of the casting slab output from the arc-shaped continuous casting machine, and completes the precision straightening operation of the bent arc-shaped casting slab in the meanwhile. In the continuous casting production process, the high-temperature casting slab discharged from the arc-shaped continuous casting machine presents a certain curved radian, which cannot meet the flatness and dimensional accuracy requirements of subsequent rolling and processing. The tensioning and straightening machine can apply uniform and stable tension force and straightening pressure to the casting slab, effectively correct the bending deformation of the slab, eliminate internal structural stress caused by arc molding, and ensure the flat and regular shape of the finished casting slab. With stable operating performance and reliable working accuracy, this equipment guarantees the continuity and standardization of continuous casting production, and lays a solid foundation for improving the quality of subsequent steel products.
