Abstract

Existing method of run-out table drive control on the hot strip mill ensures the required strip tension by setting a difference between speeds of the delivered strip and roller bodies. Such difference results in a higher wear rate of roller bodies and their more frequent replacement, entailing high expenses. Thus, a currently important objective is to increase efficiency of run-out table drives on hot strip mills. The paper describes a method to calculate required torque of an electric drive of run-out table rollers in a variety of strip delivery modes, using results of experiments carried out on mill 2000 at public company “Magnitogorsk Iron and Steel Works” (MMK). We adjusted mandatory process requirements for a run-out table roller drive with regard to a decreased wear rate of roller bodies and the improved strip surface quality. The authors developed a method to control a drive of run-out table rollers, ensuring compliance with new process requirements. Efficiency of the offered technical solutions was under an experimental evaluation.
