Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force applied through a set of rolls. The cross section of the slab is reduced by the hot rolling process.

• Rolling is the most widely used forming process, which provides high production and close control of final product. •The metal is subjected to high compressive stresses as a result of the friction between the rolls and the metal surface.Rolling process Note: rolling processes can be mainly divided into 1) hot rolling and 2) cold rolling. 3.

So tolerance for the shape at the hot rolling process is rather high. On the other hand. The cold rolling process is carried out at low recrystallization temperature and it produces relevant small and thin pieces and temperature is low, therefore deformation becomes relatively difficult than the hot rolling process.

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

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 …

The evolution of microstructure in hot rolling of aluminium alloys depends on the interaction of the main process parameters: temperature, strain, strain rate and inter-stand time (Hirsch, 2006a, 2006b).The hot strip geometry and microstructure also affects the final sheet geometry and properties, also after final cold rolling, so special attention must be paid to the hot mill process ...

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.
