Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. This produces sheet stock with good thickness tolerance and surface finish. Introduction Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed.
Also strip flatness measuring equipment mounted at one or both ends of the mill combined with multizone workroll cooling to meet the highest demands for flatness. Twostand reversing cold mills Primetals Technologies'' two stand reversing cold mills combine the flexibility of singlestand reversing mills with the capacity of conventional coiltocoil tandem mills at substantially .
Cold Rolling Mill Work Roll Category： Shaft roll/ Mill roller Forged steel work roll performs as a tool to transform materials under normal room temperature, therefore, it is the most wear and tear spare parts during the rolling process .
One of the important factors in cold rolling is the friction coefficient between strip and work roll. Friction coefficient has a close relationship with surface roughness of the work roll. Therefore, highly wearresistant work rolls with small diminution of roll surface roughness due to slippage in the bite between strip and rolls have been required for stable rolling operations.

Compared with the hot roll, the cold roll only rolls the coldrolled piece, which is usually cast after smelting and often needs to be forged. With the development of casting technology, the cold roll is forged. It is being implemented continuously. The cold roll has a cold ...
other applications (cold rolling, back up rolls) have similarities in other components. Therefore I hope this book will be useful in giving a general understanding of especially big components large cross sections which might suffer from damage for various reasons.

Shape and Gauge Control of Strip in a Cold Rolling Mill The economic efficiency of metal rolling processes is strongly correlated to the quality level of the endrolled products. The latest efforts to increase the quality of the end rolled products in rolling processes have been mainly focused on the largescale application and use of automation control advanced methods.
cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 5075 mm. 2. First intermediate roll (tapered), diameter between 904.

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified ...
As cold rolling of steel requires a lubricant in order to fulfil the lubrication role, oil is necessary. Hence, wateroil mixtures are used with a percentage of oil in water of approx. 5%. In most cases emulsions are the common coolants for cold rolling, where the oil and ...
