The cold rolling process provides a more refined surface, improved mechanical properties and excellent thickness product precision. Cold rolling mills are largely divided into the TCM (Tandem Cold Rolling Mill) and the RCM (Reversing Cold Rolling Mill). In the TCM, material passes 5 or 6 rolling mills continuously to obtain the desired thickness, ...

Cold Rolling,: ,Cold Rolling, is the method of metal forming generally, this ,process, is done by passing the metal stock through the pair of one or more rollers to achieve uniform thickness or decrease in thickness, with the increase in length.

Hot & Cold Working and the Rolling Process
Hot & Cold Working and the Rolling Process

In cold rolling, the metal piece is not heated immediately prior to rolling but the temperature of the workpiece will rise due to the frictional effects of rolling. Steels that are cold rolled become work hardened and annealing is required in order to obtain the desired hardness. The difference between hot rolled and cold rolled steels is the mechanical and chemical properties of the end products.

11/9/2014, · ,Cold rolled steel, is essentially hot rolled steel that has had further processing. The steel is processed further in ,cold, reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers ,rolling,. This ,process, will produce steel with closer dimensional tolerances and a wider range of surface finishes.

Cold working - Wikipedia
Cold working - Wikipedia

Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc.:p.375 Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. They generally have the …
