Translated from Metallurg, No. 10, pp. 60–65, October, 2014.
This article examines ways of reducing the consumption of rolling-mill rolls, extending their service life, improving the use of existing rolls, and introducing new rolls. Among the methods that can improve roll use are moving rolls to different stands of hot-and cold-rolling mills and implementing a system to assemble sets of rolls for the mills. The patterns of movement of the rolls need to be taken into account as part of the roll-use strategy. With allowance for these patterns, the company ArselorMittal Temirtau calculated the roll-changing schedule that is optimum for its continuous 1700 wide-strip mill from the standpoint of minimizing the total wear of the work rolls in the finishing stands during service. A model containing a criterion for moving rolls among different stands was used to evaluate the operating conditions of the rolls on the cold-rolling mills in sheet shop No. 3. Values were recommended for the allowable reductions in the rolls’ diameter in each stand of these mills.
