Sep 11, 2014 Hot Rolled Steel. 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 steels 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.
Composite rolls are the best selection for the last stand of rebars rolling mill right now. Based on the good wear resistance, composite rolls has replaced cast iron rolls for the last stand of rebars rolling mill. It could keep higher rolling tonnage and reduce the changing times of mill rolls. Compared the cost of rolling tonnage per ton between the composite rolls and the cast iron rolls, composite rolls have
