Surface leveling of steel strips can be achieved through various methods. One commonly used technique is roller leveling, where the steel strip is fed through a set of high-pressure rollers. These rollers exert force on the strip, gradually bending it in the opposite direction of surface irregularities, effectively leveling the surface. Roller leveling can be performed as a standalone process or integrated into a continuous processing line, such as a rolling mill.
Another method employed for surface leveling is tension leveling. Here, the steel strip undergoes tension forces as it passes through a series of bridle rolls positioned at different angles. These rolls stretch and elongate the strip, reducing surface irregularities and enhancing flatness. Tension leveling is particularly effective in eliminating defects like crossbow and center buckle in the steel strip.
Moreover, some steel strips may undergo temper rolling, a process in which the strip is heated and rapidly cooled. This alters the metallurgical structure of the steel, improving its flatness. Temper rolling also enhances the mechanical properties of the strip, including hardness and strength.
It is important to note that the specific surface leveling process employed may vary depending on the requirements of the steel strip and desired end product. Different combinations of roller leveling, tension leveling, and temper rolling can be utilized to achieve the desired surface quality, flatness, and dimensional accuracy of the steel strip.

Steel strips are processed for surface leveling through a series of mechanical operations, such as rolling, stretching, and annealing. These processes help to remove any imperfections or unevenness on the surface, ensuring a smooth and even finish.
