METHOD FOR CHANGING OF LINEAR ROLLING MILL STANDS WORKING ROLLS Russian patent published in 1994 - IPC

FIELD: linear rolling mills. SUBSTANCE: method includes disconnecting spindles from rolls of adjacent stands; removal of roll set, changing of the set for the new one; mounting of the new set. The distinctive feature of the method is that disconnection of spindle is effected through moving apart the stands with roll sets relative the supports with mounted spindles in the direction of roll axes; connection of spindles to the new roll set is effected by moving all stands together with the roll sets. The working line of linear rolling mill incorporates working stands provided with roll sets and mounted on a platen, and a support for spindle fixing. The stands are connected together and to the drive through spindles. To realize the method each of the working line supports, placed between the working stands, and the platen are provided from the drive side with hydraulic cylinders for disconnecting the spindles, and from the side opposite to the drive side the platen is provided with an actuator for connecting the spindles, with working stroke of connecting hydraulic cylinder twice as large as that for disconnecting hydraulic cylinders. EFFECT: enlarged operating capabilities. 3 cl, 4 dwg
