Cold rolling of pickled hot rolled strip is accomplished by processing steel strip through a rolling mill which has an entry end reel for uncoiling the pickled hot rolled coil and an exit end reel for coiling of the cold rolled strip. In between, there are one or more (normally up to 6 nos.) rolling mill stands for carrying out the cold reduction.

Cold Rolling Mill Process. Introducing cold pilger mill technologyul 11, 2006 cold pilgering is a longitudinal coldrolling process that reduces the diameter and wall thickness of metal tube in one process stepepending on the material, the cold pilger process achieves crosssection reductions of more than 90 percent in a.
Cold rolling involves a similar process to hot rolling, however the steel is subjected to further processing. After being rolled, the steel is cooled at room temperature in cold reduction mills. After the steel has cooled, it is subjected to annealing and/or tempers rolling, in order to provide a wide range of surface finishes and more accurate dimensional …
After slitting these hot rolled strips are acidly pickled through the continuous pickling line for removal of scale. The Pickled coils are cold rolled on 4 Hi AGC cold rolling mill to obtain the required thickness and annealed in HSD fired bell-type annealing furnace for bright annealing.
The quality of cold rolled flat products is a decisive factor for the metals industry. The ABB process and power system, designed for cold rolling mills, offers advanced solutions for quality supervision and analysis to meet your cold rolling steels needs in terms of thickness tolerances, flatness and surface characteristics.
Modern cold mills process takes in hot band coils and roll and continue to make them thinner and have final thickness around 0.2 -0.7 mm as shown in figure 4. Based on figure 4, firstly, the coils ...
Cold rolling is used to reduce the temperature of the material being worked with while also increase how hard and strong the material gets during the rolling mill process. During this process, the overall finish and granule structure of the material is is …
Fully continuous cold strip mill 2 COLD ROLLED STEEL SHEET Manufacturing process Manufacturing process Cold rolling The thickness accuracy of cold rolled products is determined by the cold rolling process. Rolling force and strip tension are computer-controlled to minimize thickness deviations during rolling, based on measurements of
Cold Compact Mill (CCM) 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. Unique Features

The cold rolling process runs at room temperature and usually under oil lubrication. In a few cases an oil/water emulsion is used, which enhances cooling but requires careful water removal before coiling. With the lubrication also used for local cooling, cold rolling allows a good control of shape, flatness and surface of the finish gauge sheet.
Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.

There are two types of processes. One is Hot rolled and another is Cold Rolled. If the strip is rolled after heating the strip above the re-crystallization temperature then it is termed as Hot rolled and if that done in room temperature then it is termed as the Cold rolled. Rolling is a process that is widely used and has very high production.
