Experimental curves of plasticity during cold rolling with tension

The plasticity curves Р=φ(h1) have been built (where Р, h1are the rolling force and strip thickness at the end of the deformation zone) during cold rolling of 08kp steel strips of 0.5 and 0.8 mm thick with relative tensions (0, 1-0, 5)σТ (where σТ is the yield strength of material) according to the experimental data of the rolling force obtained in a laboratory facility. The calculated and experimental curves Р=φ(h1) have been compared. It has been determined that modern methods of calculating the parameters of cold rolling with tension provide satisfactory accuracy of the plasticity curves Р=φ(h1) for cold rolling.
