Steel PipeSteel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them …
From Wikipedia, the free encyclopedia Strip steel or cold rolled strip is a steel product that is produced from a hot rolled strip that has been pickled. The coil is then reduced by a single stand cold roll steel mill straight away or reversing mill or in a tandem mill consisting of several single stands in a series.
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap . Contents 1 History 2 Integrated mill
Most of annealed low carbon steel strips are tempered since they are too soft (HV<110) in annealed condition. Bending and deep drawing operations of soft annealed steel may cause formation of kinks (cross breaks) and stretcher strains, which are the result of localized stretching of the strip at low cold deformation beyond the yield point.Light tempering of …
The end result was the closure of the hot-strip mill and the elimination of its 930 jobs in 1992. It was replaced by a new slab caster that provided steel slabs for Middletown. 2 The Sinter plant, cold strip mill, temper mills, pickling lines, annealing lines, and machine shop all closed by 1995.

Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around 1.25 to 13mm. How does this work? First, the slabs coming from the continuous caster are pre-sorted in the slab yard.

Hot rolled steel is steel that has undergone the rolling process at a temperature above its recrystallization temperature (usually 1700° F or greater). Compared to unprocessed steel, the processed material exhibits greater formability and workability, making it easier to work with in subsequent processing operations.
