The questions of vertical and horisontal slabbing stands electric drives interaction, under joint metall roling, when the metal remains in both stands simultaneously, are examined. It's shown, that on the control system's designing, it's necessary to keep in mind the distinctions of electric drives interaction under joint rolling in vertical and horisontal stands simultaneously. Involving significant power difference of vertical and horisontal electric drives, the control system with serial assignment signal transmitting, is preferable.

The questions of synthesis and optimization of twice multiple integrating speed control systems of electric drives with considering of constraints of acceleration and tug, has described. The solutions, providing of maximal quickaction of system, under required constraints.
