Square billet secondary reheating equipment is a key supporting device for optimizing the rolling process of square billets, specially developed for the temperature deviation problems in continuous casting and hot rolling production. It makes up for the temperature defects of square billets in the production process and provides stable temperature guarantee for high-quality rolling production.
The core function of the equipment is precise temperature compensation and uniform heating. In the continuous casting process, square billets often have uneven temperature distribution, including low overall temperature and obvious temperature difference between head, tail and edge parts. These problems will lead to unqualified plastic deformation during rolling, resulting in product defects such as surface cracks and dimensional deviation. This secondary reheating equipment can perform fixed-point and quantitative supplementary heating for low-temperature areas of square billets, controlling the overall temperature error within a precise range and eliminating temperature difference defects.
In addition, the equipment can effectively improve the rolling processing performance of square billets. Appropriate secondary reheating optimizes the internal metallurgical structure of steel billets, reduces rolling resistance, reduces the loss of rolling mill equipment, and improves the rolling yield. It can well adapt to hot charging and hot delivery production lines, solve the production bottleneck caused by unstable billet temperature, and ensure the continuity and stability of the rolling process.
For steel enterprises, this equipment not only improves the surface quality and mechanical properties of finished steel products, but also reduces the rate of defective products and production loss. It is an essential energy-saving and efficiency-enhancing device for upgrading modern square billet rolling production lines.
