The program is a detailed treatment of mill automation system design and practical UK The current state of automation and control for hot rolling mills structure 2012 1.5.4 Controlled rolling. Controlled rolling is a means by which the properties of steels can be improved to a level equivalent to those of more highly alloyed or heat-treated steels. Controlled rolling consists of three stages: (a) deformation in the recrystallization region at high temperatures,
