The main mechanical hazard is the nip between the main mill rolls in forward and reverse motion.May 30, 2013 Hot strip mill were developed in America in the first half of the twentieth century. Basic concept of the rolling. Rolling is a process used to shape metal into a thin long layer by passing it through a gap of two rollers rotating in different directions clockwise and anti-clockwise.rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

Rolling Process Slideshare Jun 23, 2018 3. Rolling is the process in which the metals and alloys are plastically deformed into semi finished or finished condition by passing between circular cylinders. Due to the frictional forces the metal is drawn into the opening. Metal Changes its shape due to high compressive forces. Both hot for drastic shape changing and cold rolling for finishing process are there.Jun 23, 2018 3. Rolling is the process in which the metals and alloys are plastically deformed into semi finished or finished condition by passing between circular cylinders. Due to the frictional forces the metal is drawn into the opening. Metal Changes its shape due to high compressive forces. Both hot for drastic shape changing and cold rolling for finishing process are there.Hot rolled products are made by a hot rolling process. In that process, the process is done at a very high temperature like over 1,700 Degree Fahrenheit. For most of the metals, this temperature is re-crystallization temperature. Such Hot Rolled products are as follows Rods Rails Plates Sheets and strip, Structural Bars, etc.
