WebFeb 10, 2024 · Cold rolling is the primary process used for cold forming metal. It involves introducing strip or coil stock between two rollers that apply constant pressure to compress the metal into a thinner sheet. Altering hardness and other material properties is possible by varying the amount of strain applied to the workpiece. WebSometimes in metal rolling practice, tension, (force), is applied to a work piece as it is being rolled. This tension may be applied to the front, (front tension), the back, (back tension), or both sides. This technique will assist the forces necessary to form the work, and is usually used on hard to roll materials.
