Oct 31 2013· Cold rolling in a tandem rolling mill The rolling mill consists of 5 7 stands having four high configuration two large back up rolls and two small work rolls Annealing at a temperature 1100 1300ºF 600 700ºC in a controlled reducing atmosphere commonly a mixture of Hydrogen and Nitrogen preventing oxidation of the steel surface
Abstract—when cold rolling stainless steel wide strips some flatness defects can occur A flat strip means that when lying on a flat horizontal surface the strip touches the surface at every point Flatness defects cause shifting strip breakage and axial forces The direct consequences are a loss of material a waste of time and a lot
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
Cold rolling The cold rolling of pickled strips takes place on the reversing four high stands with roll surface widths of 1200 mm 1700 mm and 1760 mm Cold rolling is defined as the process of forming a given metal below its typical recrystallization temperature by rolling During cold rolling the crystals of the metal are strongly
The Cold Rolling Mills are used for reducing the thickness of sheet/ strip/ coils of various metals to the desired thickness and to improve various properties like surface finish strength thickness tolerances and achieving required hardness like full hard half hard quarter hard etc Normally these mills are made in 4Hi 2Hi and 6Hi configurations
