rolling (metalworking) - wikipedia,in metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. the concept is similar to the rolling of dough. rolling is classified according to the temperature of the metal rolled. if the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling….specification of work roll size for dcr mills,classification of rolling mills ispatguru. the upper and the lower rolls are driven while the middle roll rotates by friction. four high mills in these types of the mills two smaller diameter rolls lesser strength and rigidity are supported by two back up rolls with larger diameters. cluster mills in this type of mills each set of the work rolls is supported by two back up rolls..2 high rolling mill - element,rolling mills consisting of two rolls or known as a 2 high rolling mill is used for anything from temper pass to breakdown of material. coil weight: 500 lbs (228 kg) 100,000 lbs (45,359 kg) separating force: 50 ust (45 mt) tolerances materials; rolling mills typically have very accurate positioning to ensure outgoing material gauge.understanding rolling process in long product rolling mill,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 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. at 114.16 tons/hour that is an additional 10,000 tons can be rolled..

the job of grinding is done by the vertical roller mill, which works like a cyclone to create a fine dust of evenly sized particles. as the feed is ground on the horizontal grinding table, hot air is pushed upwards from underneath forcing the smallest particles to rise. get price.,cold rolling – uptime,maillis uses cold rolling mills to produce rolling products with the smallest possible thickness tolerances and an excellent surface finish. given an entry steel coil of 4 tons weight, 233 mm width and 2 mm thickness, maillis produces steel straps over the whole thickness spectrum down to 0.4 mm.
