The first in the USSR rolls for hot-rolling mills were produced from ingots weighing up to 40 tons at Uralmashplant in 1934. The plant began producing large ingots, weighing 60 tons and more, in 1935-1936, which allowed to manufacture large backup rolls for rolling mills.
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
