John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the

The hot strip mill can produce products from 1,6mm to 13,0mm thick depending on the grade. From Saldanha thicknesses from 1,5mm can be supplied. See thickness ranges in Hot Rolled Price List. The dimensions available are given in the data sheet: Hot Strip Mill Product Dimensions (file reference ).
JSW cold rolled closed annealed (CRCA) coils and sheets are produced at our stateoftheart cold rolling mills (CRMs) in Vijayanagar. With our cuttingedge facilities, advanced operational technologies, rigorous inspection processes and integrated quality control, we ensure that everything made at our CRMs is of the highest standard.
The forming machine has two main parts: breakdown and finpass sections. Once welded, the tube can be left round, though it undergoes further forming to size it to a more accurate outside diameter. The sizing section shown in Figure 3 has round roll stands with specialty reshaping stands toward the exit and a double turkshead to finish. Used ...

Cold Rolled Steels can be joined using accepted welding practices. SURFACE FINISH Cold Rolled Steels are manufactured with a matte finish obtained by rolling with specially roughened rolls on the cold mill and the temper mill. This finish helps to maintain effective lubrication during metal forming and improves the appearance of painted surfaces.
Cold rolled sheet steel is produced from hot rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. 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.

Many intermediate metric or inch sizes may be ordered to your specifications without penalty of tool costs or delivery time. Heavywall tubing — in thicknesses as great as 0 ...
CSI''s Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.

best condition for rolling and the achievement of subsequent properties. The strip from the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures and ).
The Detroit plant was a finishing facility for sheet and strip products only. Principal operating units were two 50inch (1,300 mm)., 4high cold reduction mills, a cold anneal and pickle line, a temper mill, two slitting lines(36in. and 24in.), and a coil polisher. The two 50in. reduction mills were essentially identical.

Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
