  • Patent number: 5085067
    Abstract: A method and an arrangement for automatically aligning horizontal rolls and vertical rolls in a universal rolling mill stand after the stand has been changed to new types of sections in a rolling mill train. The axial geometric configuration of the vertical rolls in the stand serve as a fixed reference value and the horizontal rolls are displaced radially and axially into roll positions which are measured by actual position indicators and from which the geometric roll gap center and the geometric roll center in the stand are determined. For taking into consideration the spring characteristic constants of the stand, the radial spring characteristic for the two horizontal rolls is determined together, the radial spring characteristic for each vertical roll is determined separately and the axial spring characteristic of one of the horizontal rolls is determined separately in accordance with one of the two axial directions.
