Difference Between Hot and Cold Rolled Steel | Metal , hot rolling coil

Sep 11, 2014 · Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.U001en Hot-Rolled Steel Sheets and CoilsHot-rolled coil is made by continuously rolling the slab, after heating the slab in the reheating furnace, by the roughing mill and finishing mill, and coiled for a easier transportation.Hot rolled coil - ArcelorMittalHot 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

Cold Rolled Steel Coil and Hot Rolled Steel Coil

Hot rolling uses slabs (mainly continuous slabs) as raw materials, and after heating, strips are made from rough rolling mills and finishing mills. The hot strip from the last rolling stand of the finish rolling is cooled by laminar flow to the set temperature. It is coiled by a coiler into a steel coil and the coiled steel is subjected to different finishing operations according to the user's different requirements.Hot rolled :: ArcelorMittal USAAll flat rolled coil steel is initially hot rolled by passing a slab through a multi-stand hot rolling mill to produce a wide variety of thicknesses up to one inch thick. Modern state-of-the-art process control computers set up and monitor all the equipment necessary to roll and coil the steel to the customer's exact specifications.Hot Rolled Steel vs. Cold Rolled Steel (Ultimate , hot rolling coilHot rolling is the rolling process beyond crystallization temperature while cold rolling is the rolling process under the crystallization temperature. The change of cold rolled steel shape is a continuous cold deformation, and the cold hardening of this process causes the strength, hardness, and toughness of hard rolled coil to decrease.
