Hot Rolled Steel. Hot rolled steel has been roll-pressed at high temperatures (over 1,ËšF), which is above the re-crystallization temperature for most steels. Sep 11,  · Hot Rolled. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over ° 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 thekeep.online: Metal Supermarkets. Hot Rolling. Hot rolling uses large pieces of metal, such as slabs or steel billets, and heats them above their recrystallization temperature. The metal pieces are then deformed between rollers creating thin cross sections. These cross sections are thinner than those formed by cold rolling processes with the same number of stages.

The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise size such as small sized section steel and thin plates. The diameter of mm, coil, all is hot rolled material. After cold drawing, it is cold drawing material. Hot Rolled Steel. Hot rolled steel has been roll-pressed at high temperatures (over 1,ËšF), which is above the re-crystallization temperature for most steels. The Hot Rolling Process. The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77, hp, and finally coiling up the lengthened steel sheet for transport to the next process.Customers often ask us about the differences between hot rolled steel and cold rolled steel. There are some fundamental differences between. Steels of different grades and specifications can be either hot rolled or cold rolled —including both basic carbon steels and other alloy steels. NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled. Hot rolling is an industrial process for re-working principally steels but also stainless steels. Steelworks melt the material. To make it. processes in the steel industry, such as hot rolling, eliminates the costly .. Table Relationshi s for themial condudivity in carbon steels as a fundion of. -
