Learn MoreCold Mill. There are three rolling mills in the cold mill. They are the heavy cold mill, light cold mill and the 3-stand tandem mill. They all perform the same task of rolling the hot band from the hot mill to the finished sheet thickness. The finished thickness is about the thickness of a sheet of paper. If the finished coil were rolled out flat it would stretch about seven miles! Tension
Learn MoreCSI's Tandem Cold Reduction Mill was completely modernized in 1997 and typically processes seven out of every eight pickled coils. Its primary function is to reduce the thickness of the steel to between 1/2 and 1/10th of its hot-rolled gauge without first reheating it. Capable of producing over a million tons annually at widths to 60" and finished gauges less than 1/100th of an inch thick

Learn MoreCold rolling is often used commercially in order to produce sheet metal, plates, and bars. When a metal is cold rolled, it is plastically deformed as it is forced between the two rolls. The metal is compressed by the rolls and the plastic deformation is in the direction of the rolling. Unlike a tensile test, no necking occurs in the metal specimen. Metal specimens were cold rolled in this
