Abstract
Electric drives of the continuous roughing train of the rolling mill 2000 OJSC «Magnitogorsk Iron and Steel Works» are described. The model structure of the interrelated electrical and mechanical systems of two interstand gaps is introduced. Mathematical model of the rolling stand electric drive and the model of the strip plate are considered as control objects. The research group noted some specific features of the modeling process for the no pull automatic control system. Model validity to the study object was evaluated. To evaluate it, transient processes characteristic for rolling were recorded by means of oscillographic testing. It was proved that in the majority of characteristic points the output error was less than 5%, which is quite acceptable. The authors believe it is reasonable to use this model to study the algorithms of speed modes coordination and to limit the impact loads in horizontal and vertical rolls of universal rolling stands.
