Hot Rolled Steel Vs. Cold Rolled Steel | Sciencing

Deze pagina vertalen

Hot rolling and cold rolling are two methods of shaping steel. During the hot-rolling process, steel is heated to its melting point while being worked, changing the composition of the steel to make it more malleable. During cold rolling, the steel is annealed, or exposed .

What Is Cold Working or Work Hardening?

Diese Seite übersetzen

Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of cold .

Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
