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 metallurgyrelated factors in ...

A stateoftheart coldrolling mill is a prerequisite for the production of steel strip that satisfies the tightest tolerance demands at high productivity levels – for carbon, stainless and special steel grades such as AHSS (advanced highstrength steel).
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.
No. 2 Mill Edge: Hot rolled or cold rolled edge, naturally formed . No. 3 Slit Edge: Approximately square edge, slitting burr intact. No. 4 RoundCornered Edge: Rounded edge, slitting fracture may be visible . No. 5 Deburred Edge: A safety edge No. 3 edge with the slitting burr rolled over
Strip steel or cold rolled strip is a steel product that is produced from a hot rolled strip that has been 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 coldrolling directly, or with the inclusion of an ...
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.
From its small beginnings in 1911, BILSTEIN has grown to be one of the most important coldrolled steel strip producers in the world. The success story of our familyowned company was made possible first and foremost by the tireless efforts and .

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.
A fullyprocessed strip is also made with a clean, uniform finish. Annealed And OnePass Hot Rolled Strip Hot rolled strip is annealed for softness and gaugecorrected 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 thickness accuracy of cold rolled products is determined by the cold rolling process. Rolling force and strip tension are computercontrolled to minimize thickness deviations during rolling, based on measurements of the strip thickness at the entry and delivery sides of the mill.
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 .
The thickness of the hotrolled strip is important in that the properties of the final cold rolled and annealed product is influenced by the percent of cold reduction. This means that the thickness of each hotrolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.
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.

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 rerolling, 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.
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.
