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.
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 ...

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.

A temper mill is a steel sheet and/or steel plate processing line composed of a horizontal pass cold rolling mill stand. Goal is to correct shape differences along the width of the coil through cold forming. The end results/advantages of temper passing and leveling are listed below.
Principles and Applications of Metal Rolling This is a book written by a practitioner. It is somewhat different from a normal textbook involving machines and equipment in the field of Mechanical Engineering. Generally stress is given to the theories and principles involved and processes are explained in great detail.
