This study analyzes the causes of scimitar bending in the slitting process of steel coils.By opti-mizing material processing and implementing regular equipment maintenance,internal stresses are minimized,and meticulous maintenance and adjustments are made to the longitudinal shearing and slitting equipment to ensure the straightness of the steel strip post-slitting.Practical solutions have been proposed and implement-ed,successfully preventing the occurrence of scimitar bending,significantly improving the product yield rate,and providing substantial support for the enhancement of production quality and efficiency.
