How does cold rolling work
Web1. Squeezing Methods of Cold Working. Cold Rolling: Cold rolling is a process in which a steel strip or plate is twisted or stretched between two rollers. This method is commonly used for surface finishing and dimensional consistency of high quality, which can help prevent harm to products and oxidation. WebFig 2, Heat Migration in Cold Mill Work rolls (Hotter regions shown in red) This localized heat input / output process results in a non-uniform distribution of heat, circumferentially around the roll and transversely across the roll body. Additionally the roll is subjected to Thermal and Mechanical Fatigue during rolling:
