An approach to analyse the special rolling of thin strip

Work roll edge contact may affect the mechanics of cold rolling of thin strip and the crown of the rolled strip. In this paper, the authors developed a modified influence function method to simulate this special rolling. The rolling force, intermediate force, roll edge contact force, the crown of the rolled strip and the edge contact length for different strip widths and traverse friction coefficients are obtained. The calculated rolling forces are compared to experimental values. The developed model is effective and applicable in the cold rolling of thin strip with work roll edge contact.
