    Cold Rolling an overview ScienceDirect Topics

    Cold rolling, even at minimal reduction per pass, if not followed by high temperature annealing between passes at temperatures ranging from 500 to 560 °C, induces relevant edge cracks, surface scuffing, particulate cracking, and interfacial debonding. Hot rolling at a temperature of about 500 °C, instead, allows one to achieve reduction level up to 95% without edge cracking or surface scuffing, even if …

    Abstract. The dynamic model of cold rolling mill based on strip flatness and thickness integrated control was proposed, containing the following sub-models: the rolling process model, the dynamic model of rolls along axial direction, and the compensation model. Based on the rule of volume flow rate, the dynamic rolling process model was built.

    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.
