Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x …

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.Hot-rolled steel is mainly produced at rolling mills consisting of stands. For example, hot-strip mills can consist of up to 15 "quarto" stands (i.e., each stand is complete with two pairs of rolls) and edgers to form the strip edges. Hot-rolled plate production using slabs includes the following steps: Feeding slabs into reheating furnaces.
