ABSTRACT:
Data representing the axial distance of the center of each groove of a work roll from a first reference location on the work roll is determined and stored in the memory of a data processing system. The work rolls are then mounted in the roll stand and the grooves of a selected "setup" roll pass are brought into alignment with each other. Thereafter, the roll stand is placed on the rolling line, the setup pass is aligned with the mill passline in the case of vertical stands, or with the mill center line in the case of horizontal roll stands, and data representing the relative positions of the work rolls to the roll stand and of the roll stand to another reference location is obtained and stored in the memory of the data processing system. This data is then employed by the system to calculate and automatically effect adjustments to the roll stand and work rolls in order to precisely align other roll passes with the mill passline or center line. Time consuming manual adjustments and repetitive trial runs are avoided, with concomitant reductions in mill down time.
