The rolling process is a metalworking technique used to shape and reduce the thickness of materials, typically metals. In this process, a metal piece is passed through a pair of rotating rollers, which apply pressure and deform the material. This method is commonly used to produce sheets, plates, and structural components. There are various types of rolling processes, including hot rolling and cold rolling. In hot rolling, the metal is heated above its recrystallization temperature, making it easier to shape. In contrast, cold rolling occurs at room temperature, resulting in a smoother finish and improved mechanical properties.
