Hot Rolled Steel 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 steel's 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.
Hot-rolled steel is a steel that had roll-passed at a very high temperature, approximately more than 2000 degrees Fahrenheit which is above the recrystallization temperature for most steel types. The heat gives steel a workable starting form and makes it easier to shape.
Hot rolled bar and coil steel melt facilities are operated at our Canton, Ohio, facility with various products being produced in Lackawanna, Lorain and Canton. Republic Steel manufactures cut-length rounds in 1" to 6-1/2" sizes, round-cornered squares in sizes 3-7/8" to 8-1/2", and hexagons in 7/8" to 2-1/2".
The hot steel is quite fragile as it is rolled and tension between the finishing mill stands must be closely controlled at very low levels in order to avoid stretching or tearing the strip. Adjustments are made as necessary to ensure …
Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel is a more highly ...

Hot Rolled Steel. Hot rolled steel products are divided into two groups: hot rolled coils produced through hot rolling and hot rolled steel plates, which are made by cutting material from hot rolled coils. Slabs produced from a continuous casting system are rolled, cooled and coiled into the sizes required by the customers.
The hot-strip mill squeezes slabs, which can range in thickness from two to ten inches, depending on the type of continuous caster, between horizontal rolls with a progressively smaller space between them (while vertical rolls govern the width) to produce a coil of flat-rolled steel about a quarter-inch in thickness and a quarter mile in length.
the primary function of the conventional hot strip mill (hsm) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling up the lengthened steel sheet for its easy handling and …
Hot rolled coil. It is a mill process which involves rolling the steel at a high temperature, which is above the steel's recrystallisation temperature. Often used in the manufacturing of staircases, the embossed teardrop pattern gives it excellent anti-slip properties, irrespective of whether the environment is dry, greasy or damp. Moreover ...

Hot rolled Hot rolled ArcelorMittal Dofasco operates a modern 7-stand Hot Mill that provides high quality Hot Rolled Steel to our Automotive, Construction, Tubular and Service Centre customers. The mill also supplies down stream operations (Cold Rolling, Galvanizing and the Tin Mill).
Production of hot-rolled steel began early in 1996, followed by the addition of a cold mill in late 1997. In the summer of 1998, further expansion pushed the mill's annual capacity to 2.2 million tons. In 2003, we added a coil-coating line with the capacity to paint 300,000 tons of steel annually to the flat-roll campus.
Hot Rolled Coil/Sheet. NAS's hot rolled coil product is available in annealed and pickled condition. The continuous mill plate product (CMP) is available in coil form or sheet form, in wide or narrow width.
Mill scale is a uniform layer of various iron oxides and other impurities that covers hot-rolled steel surfaces. When machinery rolls the hot steel to form it, the air's oxygen reacts with the hot iron and creates these oxides. Mill scale has a black or black-blueish color and spreads evenly over the entire metal's surface.
Steel prices may well trend lower in 2021, according to experts. Steel Market Update's check of the market on Oct. 12-13 showed a base price for spot orders of hot-rolled steel of $650/ton. That benchmark hot-rolled price began the year at $610/ton and was at $580/ton in March when COVID-19 hit.

Mill scale is found on all hot-rolled steel products unless processed in a protective atmosphere or descaled (e.g., for galvanizing). At hot rolling temperatures, an inner layer of wüstite, FeO, exists between the steel and magnetite.

Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.
The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create optimum material properties.
