Sep 11, 2014· Hot Rolled Steel. 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.
This is the starting point of the hot rolling mill practice. Reheating Furnace x Cold stocks are heated to make them soft and thus suitable for rolling. x Furnace has three parts: walls, roof and hearth. Furnace is lined with several layers of refractory bricks.
the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04). Cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per
Operation of Rolling Mills Rolls Rolls are the tools of the rolling trade and the way they are used to execute their duty of deforming steel is in many cases largely determined by the roll pass designer.

Rolling processes date back to 1779. The first rolling mill was built in Fontley, Hampsire where Henry Cort developed and received patents for his ideas. The two types of temperature-dependent rolling processes are hot rolling and cold rolling, and they each have their own specific use. Hot Rolling
Hot rolling breaks the grain structures and destroys the boundaries, giving rise to the formation of new structures with strong boundaries having uniform grain structures. Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills.
