Hot Cold Working and the Rolling Process

As shown in the figure below, the rolls in a 4high rolling mill are subjected to four kinds of deformation: (i) deflection of the backup rolls, (ii) deflection of the work rolls, (iii) flattening of the work rolls caused by contact with the backup rolls and workpiece and (iv) flattening of the backup rolls caused by contact with the work rolls.

Common Rolling Defects and How to Combat Them

Cambering of rolls is one of the most common solutions to alligator cracking. By applying the camber on rolls in the opposite direction, the surface in contact with the sheet becomes flat after a deflection. Wavy Edges . One of the most common rolling defects is the occurrence of fibers at the edge, which are longer than those at the center.
