Rolling (metalworking) Wikipedia Modern 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 Roll Pass Design and Mill Operation During this time we will cover the basics of metal deformation, the rolling of steel, and Roll Pass Design concepts. The course will provide the participants with the theoretical knowledge, practical skills, and confidence to deal with day-to-day roll pass, quality, and production issues.

NUMERICAL SIMULATION IN ROLL PASS DESIGN FOR BAR The roll pass design proposal takes into consideration the lower plasticity of certain steels. Another special requirement was the shortest possi-ble work length of the rolls. The standard odd number of passes was used because of the presumption that the roll pass design is a preparatory sequence of the labora-tory rolling mill.
