TOLERANCE HANDBOOK

Sep 11, 2014· Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.

Section Rolling Mill | Steel Plantech

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 ...

Cold roll forming is a method of shaping hard metals, such as steels and stainless steels. Very precise, complex cross-sections can be created, and long lengths of these sections can be consistently reproduced. Along each length, features such as holes, slots, or embosses can easily be added, making the roll forming process a very cost effective method of achieving a strong, multi-functional ...
