FIELD: rolled stock production. SUBSTANCE: in order to lower labor consumption at guiding strip to rolls and to decrease roll wear and fitting wear, changeable pass 4 is being mounted between guiding rulers 3 with use of dent-recess joint 9. Guiding passages are provided on cylindrical cutouts of a nose part of the pass 4, coaxial with generatrices of sized portions of rolls 2. A lengthwise axis of the dent-recess joint 9 is coincided with a symmetry axis of nose parts of rulers 3 and the pass 4. The pass 4 is provided by means for it controllable motion and fixation 6,5 respectively. EFFECT: lowered labor consumption and decreased time period upon guiding strips to roll grooved pass, decreased roll and fitting wear. |
