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 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
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.
What is Hot Rolling Mill? A rolling mill is a device meant for pressure shaping of the metals or other materials between the rotating rolls. It is basically an automatic system or cluster of machines to perform both rolling and auxiliary operations including transportation of billets to heating furnaces and mill rolls, rolled material, metal after rolling, and many other functions.
