Cold Rolling Mill Complex | ProTenders. Cold Rolling Mill Complex Industrial. Abu Dhabi, UAE . The project''s scope consist of steel coldrolling 250,000 tonnesperyear (t/y) plant located in ICAD III, Abu Dhabi, which will produce galvanised steel. After the plant is complete, UIS plans to double the capacity to 500,000 t/y in the second phase.
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 coldreduction mill have their ...
Usually, coldrolled strip cannot be used as rolled, because it is too hard and has low ductility. Therefore, it is annealed in batch or continuous annealing plants (see below Treating of steel: Heattresting: Annealing). After annealing, the strip is coldrolled to about a 3percent reduction on a temper mill to improve its physical properties.
Cold Rolling eFunda. Introduction: Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of strain introduced determines the hardness and other material properties of the finished product.
COUPLED PICKLING LINE TANDEM COLD MILL Highcapacity production of highquality products. For a wide range of product applications, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and coldrolling processes.
The W 50 DC rumbler is a standard W 50 DC cold milling machine with an optional rumbler attachment installed. The rumbler attachment permits highproduction cutting of milled rumble strips in the standard, preferred 16in. width at speeds of up to 180 fpm. The Wirtgen rumble strip milling attachment makes the W 50 DC even more valuable to an owner.

The numbers, and sometimes letters, following this prefix describe the mill''s geometry, the relative size of its work roll, and the widest strip that the mill can roll. The number immediately following the "ZR" indicates the mill "section" size comprising a combination .
Thin Strip Profile Control Capability of Roll Crossing . Controlling cold strip profile is a difficult and significant problem has been found in industry during thin strip rolling. At present choosing the new type of strip rolling mill is the one of main methods to control the strip shape quality in cold rolling.
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.
20Hi ZR Mill, HZ Mill. The ZR mill uses ultrasmall diameter work rolls to efficiently roll highhardness materials such as stainless steel, electrical steel strip, and phosphor bronze. To the original high rolling reduction capacity of the mill, we have added the double ASU (shape control mechanism) originally developed by our company.
