During roll forming machine design, it is assumed that the imcoming material does not have cable, bow and twist. Roll Forming Mill Affect Roll Forming Machine Design. Rolls are designed to form the material and they must match the roll forming mill.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
Aug 16, 2001· If the forming section sends improperly formed tube to the sizing section, irregular tube size can result. The operator also should check for bent shafts, oversized bores on the tooling, or undersized outside diameters (ODs) on the driven shafts. The integrity of the side roll .
