Analysis of tension and deformation curvature in strip tension levelling
In this paper, a new method considering the combination of tension and deformation curvature which results in less deformation energy under a certain elongation is presented at the first time. The calculation results show that when the elongation is less than 1 %, the tension which is about 1/6 yield stress will consume less energy. If the tension decreases from 1/4 to 1/8 yield stress, the deformation energy of strip with yield stress of greater than 450 MPa decreases significantly. This study can help determine the processes parameters of strip tension levelling effectively.
