This is a lower cost option where the degree of spheroidization, dimensional tolerances or surface finish may not be as ...

The thickness of the hot-rolled 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 hot-rolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.

The hot strip mill supplies coils for cold rolling mill, strip shearing and slitting units as well as a finished product for shipment directly to the customers. Most material is transported out of the mill area by an automated coil handling system to the storage aisle.

The cold rolling of metal strip is one process in which a sequence of processes is performed to convert the raw materials into a finished product. It is a deformation process in which the thickness of the strip is reduced by compressive forces exerted by two opposing rolls (normally in a four-high arrangement).

Hot Strip & Cold Rolling Mill Product Yard Steelmaking Pig Iron Plant There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform.

Cold-Rolled Strip (Sheet) Sheet steel that has been pickled and run through a cold-reduction mill. Strip has a final product width of approximately 12 inches, while sheet may be more than 80 inches wide. Cold-rolled sheet is considerably thinner and stronger than hot-rolled sheet, so it will sell for a premium (see Sheet Steel). Cold Working ...

To make gauges lighter than the hot strip mill can produce economically. To produce sheet and strip of more uniform thickness. Cold rolled base – Coils that are cold worked or reduced to gauge on the tandem mill. Cold rolling – Term applied to the operation of passing unheated metal through rolls for the purpose of reducing its gauge.

In short, the workpiece is heated, the red and hot steel pieces burned on the equipment machine have been rolled many times, then cut and cut into a steel plate. The cold rolled coil is used as raw material. After stripping off the oxide skin, the cold rolled coil is used for cold treatment, and the finished product is coiled into the hard coil ...

After having passed through the cold rolling mill, the steel strip is hardened. This entails that it is no longer able to be processed further. This is why, in order to make the steel cold deformable, it needs to undergo a heat treatment. This can be done in the batch annealing section or in the continuous annealing and processing line.

After cold rolling, the steel strip is hard and brittle with its grains elongated in the rolling direction. To obtain the desired grain structure and to improve the mechanical properties, the strip is annealed at an elevated temperature in a reducing atmosphere. Unique Features Uniform annealing under hydrogen atmospheres

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 ...

2 Hot-rolled raw materials are produced with severe scratches, chisel marks and other defects, which are torn after cold rolling. Edge rupture The edges of the steel strip are cracked and penetrate deep into the inside of the steel strip in the width direction.

Cold rolled stainless steel strip is manufactured from hot rolled, annealed and pickled strip by cold rolling on polished rolls. Depending on the thickness desired, the cold rolling requires various numbers of passes through the mill to effect the necessary reduction and to secure the desired surface characteristics and mechanical properties.

If the strip is rolled after heating the strip above the re-crystallization temperature then it is termed as Hot rolled and if that done in room temperature then it is termed as the Cold rolled.Rolling is a process that is widely used and has very high production. Working Principle of Rolling Process:

Cold rolling in a tandem rolling mill. The rolling mill consists of 5-7 stands having four-high configuration (two large back-up rolls and two small work rolls). Annealing at a temperature 1100-1300ºF (600-700ºC) in a controlled reducing atmosphere (commonly a mixture of Hydrogen and Nitrogen ) preventing oxidation of the steel surface.

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.

How Does a Cold Rolling Mill Work? The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength.

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 …
