The Hot Rolling ProcessCalifornia Steel
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.

What is "Cold Rolling" Stainless Steel and Other Metals
How Does a Cold Rolling Mill Work The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers which compress it down and squeeze it under high pressure just below its ultimate tensile strength.

Metal rolling oils Energy Technologies
Metal rolling is the process of stretching a piece of sheet metal to a certain thickness by increasing its length. Friction control between metal rolls is critical low friction is desirable in some places but if friction is too low in other contact areas it can cause the rolls not to flatten the metal effectively creating pits and smears.

Controlled rolled down from the normalising temperature yet fully austenitic (above the Ar 3 temperature) followed by a rapid cool of approximately 10°C/sec. The aim of this process is to refine the grain size by controlled rolling and to increase the strength by suppressing the formation of ferrite and pearlite in favour of a strong tough bainite.

Cold Rollingprocess overviewEngineeringClicks
Cold rolling is a process that occurs after hot rolling in order to reduce the thickness increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process but the improved mechanical properties increase the value of the finished product whether that is a sheet strip or coil.

Hot and Cold Rolling Explained Capital Steel Wire
Cold Rolling. Cold rolling is a process which passes metal through rollers at temperatures below its recrystallization temperatures. This increases the yield strength and hardness of the metal. This is done by introducing defects into the crystal structure of the metal creating a hardened microstructure which prevents further slip.

Hot Cold Working and the Rolling Process
In cold rolling the metal piece is not heated immediately prior to rolling but the temperature of the workpiece will rise due to the frictional effects of rolling. Steels that are cold rolled become work hardened and annealing is required in order to obtain the desired hardness.
