"Temper rolling" is a term that refers to a processing method used to increase the strength and durability of metals. This process is commonly used to improve the properties of metal alloys, particularly steels.
Temper rolling involves creating plastic deformation on the material's surface to refine grain structure and reduce internal stresses. During the process, the metal is first heated at high temperatures and then cooled. The heat treatment alters the metal's microstructure, resulting in a more homogeneous and harder structure.
Temper rolling reduces the size of crystal grains within the metal and makes them more uniform. This enhances the strength of metals and provides better durability, fatigue resistance, and hardness. The surface roughness of the metal can also decrease as a result of temper rolling.
This process is often employed in the production of steel strips, plates, or sheet metal. For instance, applications of temper rolling are widespread in the automotive industry, including the manufacturing of vehicle chassis, body parts, and steel pipe production.
Temper rolling is a significant process for enhancing the properties of metals and achieving desired performance. Materials produced using this method tend to be more durable and possess higher strength.
