There are several methods used to level steel coils, including roller leveling, stretcher leveling, and tension leveling. Roller leveling involves passing the coil through a series of rollers that gradually bend and flatten the steel to remove any curvature or unevenness. Stretcher leveling uses hydraulic or mechanical forces to stretch the steel in order to eliminate any residual stress and improve flatness. Tension leveling applies tension to the steel coil while it is being passed through a series of rolls, which helps to remove any waviness or shape defects. These methods are employed depending on the specific requirements and desired flatness of the steel coils.
