Mill spring is a flaw in which the rolled sheet is thicker than the thickness needed as high rolling forces the rolls to deflect. The occurrences of mill's elastic deformation happen when steeper rolls are used, i.e. high stiffness rolling material or elastic constant, we might prevent mill spring. The elastic constant for mills usually ...
