ABSTRACT:
A rolling mill comprising a movable mill stand mounted in slideways and enclosing grooved mill rolls whose necks are coupled with a hydraulic drive and with gear wheels in mesh with each other. A drive for reciprocating said movable mill stand is equipped with at least two linear inductors installed immovably and at least two electrically conductive bars connected rigidly to movable mill stand separators and braces. The bars are adapted to move intermediate of said inductors and have a length exceeding that of said inductors and begin of a value of at the maximum transfer of said movable mill stand. By establishing inductive currents and, hence, electromagnetic forces in the bars, the inductors develop through said bars pulling or pushing forces acting on said movable mill sand sufficient to provide a requisite roll force. The mill roll hydraulic drive is an auxiliary one.
