What Is A Rolling Mill? | Metal Processing Machinery,
In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams,What is "Cold Rolling" Stainless Steel and Other Metals,,In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.Metal Rolling - Manufacturing Process,Rolling mills often vary in the type, number, and position of rolls.
