The Hot Rolling 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.

Thermo Mechanical Control Processing in Rolling Mills

Metal Forming Processes – IspatGuru

May 05, 2016 · Early rolling mills used flat rolls for making sheet and plate, and until the middle of the 18th century, these rolling mills were driven by water wheels. During the Industrial Revolution at the end of the 18th century, processes were devised for making iron and steel in large quantities to satisfy the demand for metal products.

Rolling Process for Steel - Steel casting foundry USA

This process helps to obtain physical qualities of metal that are usually not obtainable by the hot rolling process. The can eliminate the errors like that of shrinkage. In short, cold rolling results in a final metal sheet that is more accurate in terms of dimensions and properties than the one that is obtained from hot rolling process.

Aluminum Rolling Process: Part One :: Total Materia Article

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.

only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal rolling conditions” - a stable, theoretical assumption - mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable

Tandem Rolling Process :: Total Materia Article

The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling. Following the threading, dynamic control loops (AGC and AFC) are closed and corresponding actuators are activated. Then the mill speed is increased during the acceleration …
