Cold Rolling Flow

At the pickling process, the oxidized scale is removed from the surface of the hot coils that were produced by the hot rolling mill. Following the pickling process, the coils are then sent to the cold rolling process, where they are rolled still thinner at cold (room temperature) conditions until they reach the thickness required for their final applications. The cold rolling process also finalizes the strip thickness accuracy and flatness. Because the steel is rolled under cold conditions, there is no oxidation of the surface, yielding an attractive metal skin. Following the cold rolling process, the cold coils become the final products after undergoing an annealing process, plating process, skinpass process and/or coating process according to their intended uses.
