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 ...

Fundamental concept of metal rolling - mtixtl
•The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling, µµµµ~ 0.2 up to sticky condition.
