A nominal roll radius of 100 mm is very close to 98 mm. Hence, the roll radius was fixed at 100 mm. The barrel length of the mill rolls is usually established by the maximum width of the strip to be rolled, the mill width usually being a few inches greater than maximum strip width. Here, the barrel length was taken as 300 mm.

Starting with a pickled and oiled hot rolled coil, the cold rolling process unrolls the metal coil and passes it between a set of work rolls, where the compressive force of the rolls reduces the thickness of the metal.
Rolling is classified into two types according to the temperature of the metal being rolled. One is the hot rolling and the other is cold rolling. Hot Rolling Process: If the temperature of the metal is above the recrystallization temperature, then the process is known as hot rolling. Cold Rolling Process:

This process is commonly used for shaping large sections of metal quickly and efficiently. In contrast, cold rolling occurs at or near room temperature, imparting greater control over the dimensional accuracy and surface finish of the metal. Cold rolling is often employed for producing thin sheets or precision components.

Cold roll forming is a rather old process for which there is a renewed interest due to its capacity to form ultra high-strength steels. For the first time ever in the literature, the manufacturing chain involving both the continuous cold roll-forming process, the in-line welding operation for closed sections and the post-cut operation is numerically modelled.
Our rolling mills are available in 2Hi and 4Hi roll configurations. Mills may be either work roll-driven, back-up roll-driven, or a combination of both. 4HI mills with work rolls are offered as small as .500″ (12.7mm) in diameter; 2HI mills are offered with rolls up to 16″ (400mm) in diameter
Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil.
