In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.

Consequently, the ingot is transferred to the breakdown rolling mill (which could be reversible) at elevated temperature followed by a high-speed, multistand, and tandem mill. The hot band is coiled and cooled to room temperature before it is cold rolled to its final thickness, typically in the range of 0.8–1.2 mm. After cold rolling, the ...

Definition of Rolling process: Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One …

Continuous Pickling Line (CPL) is feed material in the form of Hot Rolled Coils(HRC) are pickled at this phase to produce a strip surface suitable for cold rolling. The project shows positive impacts, which reduce the number of re-processing raw material (HRC) and reduce the number of defects and increase production tonnage.

When cold rolling, the local tensile strength exceeds the limit, so that the material is partially broken to form holes; 2 Hot-rolled raw materials are produced with severe scratches, chisel marks and other defects, which are torn after cold rolling.

Unlike mills producing a light gauge strip, plate mill provide axial shifting between passes and roll bending directly during rolling. Thus, the specified shape of the rolling cross-section shown in Fig. 1 as contour lines is ensured.

Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to 2.5 million tons of cold rolled steel annually. The advantages of cold rolling. Cold rolled products have the following advantages over hot rolled: greater dimensional accuracy

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
