WhatsAppعرض المزيدModern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to

A cost model was developed and evaluated by system dynamics simulation (Sterman 2000) in order to analyse the effect on overall mill economy as margin costs for reheat energy, tied capital and work roll consumption vary in response to changed setup times. In the sections that follow, we will briefly cover production planning
