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. The strip is reduced to approximately final thickness by cold-rolling directly, or with the inclusion of an ...

A fully-processed strip is also made with a clean, uniform finish. Annealed And One-Pass Hot Rolled Strip - Hot rolled strip is annealed for softness and gauge-corrected for closer thickness tolerances on a cold rolling mill. This is a lower cost option where the degree of spheroidization, dimensional tolerances or surface finish may not be as ...
The feed stock of cold strip mills are coils rolled by hot strip mills. If abnormal conditions, such as excessive roll wear, occur in the hot strip mill, thickness profile ridges are produced on the hot rolled strip. When the hot rolled strip with ridges is subsequently fed into a cold mill, local buckles are produced in the cold rolled strip.

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 market of rebar and wire rod is going to be saturated in few years, the spring of hot rolled coil, cold rolled coil, galvanized coil, color coated coil are coming.
Cold rolled steel is a product that has been cold reduced, as opposed to hot rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape. The benefits of cold rolled sheet include excellent performance in applications that require deep drawing and intricate bending and forming.
Our precisely designated Copper Strip 4 Hi Cold Rolling Mill is ideally utilized for thinning the piece of copper to develop strip. These rolling mills are developed by making use of premium grade materials and sophisticated technologies to ensure proper rolling of copper strips.
The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.
Looper equipment. Loopers are material accumulating devices used for transferring, winding, and unwinding rolled steel. In surface treatment lines such as CAL and CGL, when the seams between coils on the inlet side are welded or the coiled steel on the outlet side is cut for continuous surface processing, or when flow is intermittent, the looper tower carriage is raised .
If all measures in the hot strip mills fail and ridges are produced on the hot band, flattening the ridges before cold rolling using a mill stand with very high local rigidity (Liu et al., 2011b, 2012) Liu et al., 2011b Liu et al., 2012 can be used to reduce the local buckles significantly. The uniformity of the metallurgy-related factors in ...
The result is that when hot-rolled steel cools, it shrinks slightly, so there is less control of the final size and shape of the finished product, compared to cold-rolled steel. Creating strip steel necessitates further processing in cold reduction mills, where the material is cooled at room temperature followed by annealing and/or tempers rolling.

Strip steelWikipedia. 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.
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale.
Farwest is proud to carry an A572-50 flatroll inventory ranging from 3/16″ to 1/2″ thick in widths of 48″ to 96″ wide. Standard lengths of 96″, 120″, 144″, and 240″ are inventoried for many stocking sizes, and can also be sourced or processed to any desired length.
strip cold rolled mill. U003en Cold-Rolled Steel Sheets and Coils. Cold-Rolled Steel Sheets and Coils are extensively used as basic materials . in automobiles electrical appliances steel office equipment various types of Cold-Rolled Coil Hot Rolling Mill Continuous Annealing Line Converter and cold-rolled steel sheet and coil mills (CDCM).
The thickness accuracy of cold rolled products is determined by the cold rolling process. Rolling force and strip tension are computer-controlled to minimize thickness deviations during rolling, based on measurements of the strip thickness at the entry and delivery sides of the mill.
The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a yield strength of 365 MPa.
