Hot Cold Working and the Rolling Process
Hot Cold Working and the Rolling Process . The hardness is generally lower than that of cold rolling and the required deformation energy is lesser as well. However most metal will experience some surface oxidation resulting in material loss and poor final surface finish. the rolls in a 4-high rolling mill are subjected to four kinds

Rolling (metalworking)Wikipedia
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
