This enables strip to be produced at very tight tolerances and productivity levels resulting in maximum yield. Markets served by customers include transport, construction and packaging. An accurate mill setup is crucial for meeting quality requirements. For this reason, Primetals Technologies cold rolling mills use physical on-line process models.

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 and accumulated steel ...

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 is excellent performance in operations that …

Oct 31, 2013 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 1100-1300 F (600-700 C) in a controlled reducing atmosphere (commonly a mixture of Hydrogen and Nitrogen ) preventing oxidation of the steel surface.

The material they’re made of originates as specialty sheet, precision rolled strip, or plate from ATI Specialty Rolled Products. It could be high-strength titanium, corrosion-resistant nickel, specialty stainless steel or some other sophisticated alloy, worked into a coil, strip, foil or plate for efficient, high-speed manufacturing. Whatever ...

Apr 17, 2019 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 steel, sometimes abbreviated to CRS, is well-known for being an extremely ductile material, and is ideal for applications where precision is necessary. It is used in many applications, like household appliances, furniture, lockers, and filing cabinets. ... Another method of cold rolling uses a reversing mill, which passes the strip ...

Oct 06, 2020 The three types of the process used in cold rolling mill include (i) single stand cold reversing mill where the flat metal strip is processed in several passes (from 3 to 7) and the coil is uncoiled–recoiled by two reels installed in proximity of the stand, (ii) two stand cold reversing mill where the reduction of the thickness is achieved with a reversing process but the number of passes (from 1 to 3) is reduced because of increasing of the number of stands, and (iii) tandem cold rolling ...

Nov 12, 2013 The tandem cold rolling of metal strip is one process in a sequence of processes performed to convert raw mate-rials into a finished product The rolling strip contact length can be approximated [6]. It is a deformation process in which the thickness of the strip is reduced by compressive forces exerted by two opposing rolls (two or

Pickled Hot Rolled Steel Sheet. Cold Rolled Steel Sheet. Cold Rolled Galvanized Steel Sheet. Our two-stand reversing cold mill is the beating heart of the Heartland Division.

A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten. It has long been recognized that some, if not most, of the variations in thickness of strip produced by a cold-reduction mill have their origin in the hot rolling process.
