Rolling defects and remedies pdf. 3 The document provides descriptions and potential causes and solutions for various types of roll defects that can occur in paper manufacturing. Some common defects mentioned include slivers, scale pits, rolled in scale, roll marks, scratches, edge cracks, pitting, digs and gouges, dents, stress corrosion cracking, roughness, poor coiling, and telescopicity. 1) The document discusses various defects that can occur during the rolling process, including problems with flatness, thickness uniformity, and shape of the rolled product. 2) It outlines factors that can lead to these defects such as insufficient or excessive camber of the rolling mill rolls, inhomogeneous deformation in the thickness direction, and defects introduced during casting. It also notes that defects entering rolling or forging will show up in the final product. This document discusses rolling defects, their causes, and remedies.
