Coil Processing: Straightening and Leveling
Steel production and processing involve continuous operations, with the last step being coiling. To avoid producing “soft” or collapsing coils, steelmakers and processors use tension during coiling. However, this process induces tensile and compressive stresses into the strip, which can lead to blank or part distortion in subsequent processes.Get more news about coil leveling,you can vist our website!Two main types of equipment are used to create a flat coil: a straightener and a precision leveler. Both bend the coil back and forth over a series of work rolls to alternately stretch and compress the upper and lower surfaces. The goal is to achieve a flat coil once the steel passes through all the rolls.Coil Set is a bow condition parallel with the rolling direction, while Crossbow is a bow condition perpendicular to the rolling direction. These coil shape imperfections can be corrected using shape control equipment like flatteners or levelers.In summary, coil leveling aims to minimize distortion before further processing, but it’s essential to control the process to avoid excessive work hardening of the coil.
