The rolling mills are similar to that used in hot rolling. The cold rolling process has the advantage of providing close dimensional tolerance up to 0.025 mm. It also improves toughness, hardness, mechanical strength, surface finish of the material. Softer metals like tin, silver, gold, aluminum and its alloys undergo cold rolling.

Rolling is a major manufacturing process of sheets and other cross sections of large length like I beam, railroads etc. It is one of a metal forming process in which the metal work piece is compressed between a set of rolls where it reduces its cross section area and increases its length. This process gives high production rate, surface finish ...

In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.

In the first part of the thesis it is shown that biodegradable synthetic water-based lubricants, which are less detrimental to the environment, may substitute conventional mineral oils and oil-in-water emulsions in cold rolling. This is also clear from [2-4].

The primary finishing refinement for sheet steel is being further hot-rolled in the rolling mills. Rolling mills are just a series of rollers and hot-rolling just means that the steel is at a high temperature while it is being rolled. Before the slabs can be rolled, they need to be reheated to about 2400 degrees Fahrenheit and then need descaled.
