Aluminum Strip Rolling Mill: Producing Top Quality Aluminum Strips

ashldAluminum strips are one of the most extensively used industrial metals that are needed in varied industries. In metal working, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. Aluminum Strip Rolling Mill is used to manufacture the aluminum strips.

Aluminum Strip Rolling Mill Technology

The hot strip production process –traditionally the molten metal is cast after refining and alloying processes into 10 to 25-ton slabs in semi-continuous casters, then preannealed, hot-rolled in single-stand or tandem hot rolling mills and, at a strip thickness of 6 to 2.5 mm, coiled at a temperature of about 300°C. More economical in terms of energy saving is the direct casting process into strips of 12 to 20 mm thickness in twin-belt casters with a continuing hot rolling process in a tandem hot rolling line at an hourly production rate of 25 kg per mm width. The suitability of this process is restricted to a limited number of alloys allowing a quick cooling without segregation.

Thin-strip and foil rolling – is the finishing operation for nearly all flat-rolled products on non-reversing single-stand rolling mills. Either universal rolling mills or groups or lines of two to five rolling mills are used. The thin-strip rolling mills used for the production of can stock provide extremely narrow strip gauge and flatness tolerances. Lithographic sheet rolling mills, in particular, fulfill high demands on the strip surface. Foil rolling mills are the most accurate in gauge and tension controls. All rolling mills used for these different purposes are equipped with specific components to ensure the quality requirements. The last pass of foil rolling is done with a double web. This requires a doubling operation of foils after the penultimate pass and a separating operation after the last pass. The finished foil typically consists of a shiny and a matt side. Both sides are used for different printing images in a later stage.

Metal Rolling Is One Of The Most Significant Fabricating Processes In The Contemporary World. The Large majority of all metal products formed today are subject to metal rolling at one point in their produce. Metal rolling is generally the first step in forming raw metal forms. The continuous or ingot casting of Aluminum Strip Rolling Mill is hot rolled into a bloom or a slab; these are the basic formation for the creation of a wide variety of manufactured forms. Blooms usually have a square cross section of greater than 6×6 inches. Slabs are rectangular and are generally greater than 10 inches in breadth and more than 1.5 inches in thickness. Rolling is most often, (mainly in the case of the conversion of a continuous or an ingot casting), performed hot.

At rolling mill, slabs and blooms are further rolled down to transitional parts like; sheet, plate, coil, strip, billets, rods and bars. A lot of these products will be the starting material for following manufacturing operations like sheet metal working, forging, wire drawing, machining and extrusion. Blooms are often rolled directly into H beams, I beams, channel beams, and T sections for structural applications. Rolled bar, of varied shapes and special cross sections, is used in the machine building industry, and for construction. Rails, for the making of railroad track, are rolled straight away from blooms. Sheets and Plates are rolled from slabs, and are really important in the formation of a wide range of manufactured items. Plates are usually considered to be over 1/4″, (6mm), in width. Plates are used in heavy applications such as; bridges, boilers, large machines, nuclear vessels, ships and tanks. Sheet is used for the fabrication of car bodies, train cars, buses, refrigerators, airplane fuselages, dryers, washers and various other household appliances, containers, office equipment, and beverage cans, to name a few of the lot.

What We Do Know About Roll Forming?


Roll forming, is a constant bending operation in which a long strip of sheet metal (usually coiled steel) is passed throughout sets of rolls mounted on successive stands, every set performing only an incremental division of the bend, until the preferred cross-section profile is attained. Roll forming is perfect for producing regular profile parts in large quantities and with long lengths.

A range of cross-section profiles could be produced; however each profile needs a carefully crafted set of roll equipment. The rolls design starts with a flower prototype that is the series of profile cross-sections, one outline for every stand of rolls. Roll contours are then consequential from the flower pattern profiles. Since the high cost of the roll sets, computer imitation is generally used for developing or validating the roll designs and optimizing the forming procedure for minimizing the material stresses and number of stands in the final produce.

Roll formed sections might have benefits over extrusions of alike shapes. Roll formed parts might be much lighter, with thinner walls probable than in the extrusion method, plus stronger, having been work tough in a cold form. Parts could be made having finished or already painted. Moreover, the roll forming process is more rapid and takes less energy than extrusion.
