Kallvalsade

Kallvalsade refers to a manufacturing process applied to metals, primarily steel, where the material is shaped at or near room temperature. This process, known as cold rolling, involves passing metal through a series of rollers to reduce its thickness and improve its surface finish and mechanical properties. Unlike hot rolling, which is performed at elevated temperatures, cold rolling does not involve reheating the metal.

The cold rolling process imparts several advantages. It results in a smoother, more precise surface finish compared to hot-rolled products. Furthermore, cold working strengthens the metal through a process called strain hardening, increasing its tensile strength and hardness. However, it also reduces ductility, making the metal more brittle.

Products manufactured using the kallvalsade process are commonly found in various industries. They are used for applications requiring tight tolerances and a superior surface finish, such as in automotive parts, appliances, furniture, and precision components. The cold rolling process allows for the creation of thinner, stronger, and more aesthetically pleasing metal products. The term "kallvalsade" is often used in Swedish and other Nordic languages to describe these cold-rolled metal products.
