ROLLING The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are descaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control
Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for rerolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and ...
Comprised of seven chapters, this book begins with an overview of the three principal methods of rolling, including longitudinal, transverse, and skew rolling processes. This text then illustrates the constrained yield stress distribution along the gap due to work hardening on cold rolling .

A ZMill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.

Cold rolled sheet steel is produced from hot rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold rolled steel is a product that has been cold reduced, as opposed to hot rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape.

Hot and Cold Rolling Explained To those on the outside, the rolling process is an unknown. The average person may be completely unaware of what rolling is, but it is something that is extremely important to know in the steel industry.
From ColdRolling to Annealing. Pickled coils are rolled to the specified thickness . by cold rolling. The ColdRolled Steel Sheets and Coils have their crystal grains enlarged in the rolling direction, making the texture hardened and brittle. In the annealing process, the coils are continuously heated in reductive atmospheric gas to form uniform
