Difference Between Hot and Cold Rolled Steel | Metal Supermarkets
The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by

60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B. Cauffiel
Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slab mills and blooming mills.
Non-Ferrous Metals - Plate Mill Systems Manufacturer from Phalodi
Hot rolling mills roll heated steel, stainless, and aluminum slabs to make hot strip with a thickness of a few millimeters to over ten millimeters. Hot coils are shipped as they are, or moved to another operation and processed to cold rolled sheet, coated steel sheet, or steel pipe.
COLD ROLLED COILS AND SHEETS - JSW Steel Ltd
Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil. Unique Features
