Mathematical model for rolling stand of the continuous cold rolling mill expressed in relative deviations
In the paper there were obtained mathematical equations characterizing basic drawing parameters in deformation zone such as metal pressure on rollers, drawing momentum, metal lead in deformation zone, band tension between stands. Also there were obtained equations for power part of electric drive, hydraulic thrust device and described interconnection of all the mill’s stands through the drawing band. Based on obtained equations describing drawing process there was developed mathematical model for one stand of the continuous rolling mill that was expressed in relative deviations of its parameters which allowed to simplify the model through its linearization in a working range.
