1. Hot rolling and rolling defects 1.1 Front and back
· Mill spring is a defect in which the rolled sheet is thicker than the required thickness because 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.
