HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped. It also allows for the ability to produce larger quantities of steel. The steel is then cooled ...

11/09/2014 · The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by annealing and/or tempers rolling.

20/07/2013 · Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 70 ± 5 degrees C. Add rubber into the mill nip and band, as a continuous sheet, onto the front roll. Using a hand knife, make two ¾-cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling bank is formed on the nip. Now the rubber is sufficiently masticated and thus ...

The asymmetrically hot rolled material exhibits a very weak rolling texture, which is different from conventional hot rolling textures both quantitatively and qualitatively. As shown, the orthotropic sample symmetry is broken and the rolling texture components have shifted from their ideal plane-strain position and thus the texture is presented in the domain 0 < ϕ 1 < 360°. As revealed in ...
