ROLL PASS DESIGN


Plastic forming of steel by rolling at elevated temperatures (rolling) is important in industry because most of steel is at some stage processed by means of this technique. Rolling incorporates large-scale man-made systems that modify the quality of immense volumes of steel and consume significant amount of resources. In particular, this industry triggers critical issues related to global environmental sustainability (pollution and energy emissions). The algorithms for roll pass design are still treated as confidential property and there are no satisfactory instructions published on the Internet. This source attempts to remedy such a state of the art. Presented knowledge is based on practical experience and extensive bibliography.
