Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

The four high mill uses this principle with two smaller work rolls each supported by a larger backing roll. Figure:145 : The cluster mill, or Sendzimir mill, uses a small work roll backed up by many other rolls. This extremely rigid setup is often used for cold rolling high strength material to a very thin width.

Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

Roller mills. Roller mills are basically of two distinct types. The first has a series of rollers which rotate around a central axis within a drum. ... Plate mills use a similar principle but are constructed of steel or ceramic plates and used more commonly in the vertical plane. Output from such a mill is low and the mill in used only for ...
