Roughing Mill - an overview | ScienceDirect Topics

Hot rolling is a process in a steel plant in which the semifinished slab is reheated to a predetermined temperature and the hot slab is rolled to make the specified hot strip in a coiled form. The role of a hot strip mill (HSM) is to produce strips from semifinished steel slabs. The resulting attributes of the rolled strip are its surface quality, thickness, width, flatness, and strip profile ...

Difference Between Hot and Cold Rolled Steel | .

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 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. Hot rolled steel is typically cheaper than cold ...
