A roller leveler main design
Abstract: The rolling in the rolling, cooling and transport process, due to various factors, often produce the shape defect. To eliminate these drawbacks, rolling on the need to be corrected in the leveler. Straightening process, a plurality of straightening roll straightening machine for bending profiles repeated several times, so that the original profiles to achieve a variety of curvature in the same direction of curvature of a single straightening, bending again for the last time after the final to achieve the purpose of straightening. Based on a simple roller straightening machine research and discourse introduces two roller straightening machine straightening straightening rod design process and design elements. Two rolls one roll is convex, one concave rollers, guide and guard plate is formed through an overcorrection bar straightening channels. By rolling curve with the realization of straightening function.
