What are the shape defects of cold rolled steel sheet? wave and camber
there are two types of shape defect of the steel material: one is wave by rolling and the other is camber.
Types of shape defects occurring in steel sheet.
Generally speaking, in the rolling process, dead flat sheets cannot be manufactured due to a variety of rolling conditions and material characteristics. There are important factors to determine the quality of rolled steel products, such as flatness, residual stress, surface quality, etc. Actually, shape defect occurs due to a complex combination thereof; among those, the two types of flatness defects are discussed separately.
Residual stress may cause the steel sheet to be warped after slitting to narrow band. The tension leveler has a role of making the residual stress distribution uniform.
Surface quality of a rolled steel is evaluated taking into account scratches, small holes, waves and the like, and is directly related to the value of the product.
In order to rectify such flatness defects, leveling machines have been installed after rolling mills. Particularly, tension levelers have a great capability to improve strip flatness, even after being divided to steel sheets.
