Improvement of the technique of calculating the energy–force parameters of pinch-pass mills for increasing the efficiency of producing cold-rolled strips

详细

New propositions are introduced into the technique of energy-force calculation of pinch-pass mills in order to determine the energy–force and technological parameters of skin rolling of cold-rolled steel strips at the minimum errors. The application of these propositions decreases the errors of calculating the forces and torques in a working stand by a factor of 3–5 as compared to the calculation according to the well-known technique, saves the electric power in the existing mills, and demonstrates the possibility of decreasing the dimensions of working stands and the power of the rolling mill engine.
