kuumavalssauksen

Kuumavalssauksen, also known as "hot rolling," is a metalworking process that involves passing a heated metal workpiece through one or more pairs of rollers to reduce its thickness and to work the metal into a desired shape. This process is commonly used in the production of steel bars, rods, and sheets. The metal is heated to a temperature above its recrystallization point, which allows it to deform more easily and uniformly. As the metal passes through the rollers, it is subjected to compressive forces, causing it to elongate and thin out. The process can be continuous or intermittent, depending on the specific requirements of the product being manufactured. Hot rolling is an essential step in the production of various metal products, contributing to their strength, uniformity, and desired mechanical properties.
