Hot rolling is a mill process where the steel gets rolled above its re-crystallization temperature. Exposure to such high temperatures makes it easier to shape and form the steel, resulting in easier products to work with. For sheet metal, rolled steel is spun into coils and left to cool. Steel shrinks slightly as it cools off, thus giving less control on the size and shape of the finished product.
Hot rolled coil - ArcelorMittal South AfricaHot rolled coil It is a mill process which involves rolling the steel at a high temperature, which is above the steels recrystallisation temperature. Often used in the manufacturing of staircases, the embossed teardrop pattern gives it excellent anti-slip properties, irrespective of whether the
ISO 13976:2016(en), Hot-rolled steel sheet in coils of This document applies to hot-rolled carbon/manganese steel sheet in coils of structural quality without the use of microalloying elements. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures. The product is produced on a wide sheet mill.
Dec 29, 2013 · The austenite phase transitions in the industrial production of hot-rolled steel coils are studied magnetometrically. Nonuniformity of the structure and mechanical properties of low-carbon steel strip over its length and width may be attributed to incomplete phase transitions in the strip on the output roller conveyer and nonuniformity of the subsequent coil cooling in regular production

Structural Steel Sheet and Coil - ASTM A568 SpecificationThis specification covers the general requirements for steel sheet in coils and cut lengths. It applies to the following specifications that describe carbon steel and high-strength, low-alloy steel (HSLA) furnished as hot-rolled sheet and cold-rolled sheet:Specifications A 414/A 414M, A 424, A 606, A 659/A 659M, A 794, A 1008/A 1008M, and A 1011/A 1011M.
The hot-rolled coil passes through the pickling line, where surface scales (iron oxide layer) are removed from the surface of the coil to give an (attractive) surface finish to the steel. In the pickling line, surface scales are removed with hydrochloric acid, and the coil is
