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 ...

the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.
