Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. At this temperature it can be shaped and formed easily, and the steel can be made in much larger sizes.

Technological control for cold rolling processes
Mass flow control Using the mass flow principle, the outgoing strip thickness at the instant of rolling can be computed from the incoming strip thickness and the in- and out coming strip speeds. By means of this mass flow control concept, high control accuracy can be achieved. Therefore it en-hances clearly the concepts of thickness feedback

Adding to the complexity, this flow rate ideally should be 25 to 30 PSI at the point of dispensing because pressure is lost within each plumbing component. The mill reservoir should be placed close to the mill and use larger-diameter pipe over shorter distances to provide the least change in coolant pressure from the pump to the mill.

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.
