Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.
description of the cold rolling process is presented. In Section 3, a mathematical model has been driven for singlestand cold rolling mill. In Section 4, architecture and learning algorithm Fuzzy Neural Networkof have been presented. In Section 5, thickness control with roll eccentricity compensation has been proposed. In Section 6,
Frederick William Wood was an executive and engineer in the steel and shipbuilding industries. His papers constitute a major source on the history of the American steel industry in the late nineteenth and early twentieth centuries.
