Külmvaltsimise
Külmvaltsimine, also known as cold rolling, is a metalworking process that involves passing metal through rollers at or near room temperature. This process differs from hot rolling, where metal is heated to a high temperature before being rolled. Cold rolling is typically performed on metal that has already been hot-rolled and pickled to remove surface scale.
The primary purpose of cold rolling is to improve the mechanical properties of the metal. The deformation
Cold rolling is used to produce a variety of metal products, including sheets, strips, bars, and rods.
