method and apparatus for automatically preregler mill in order to compensate for variations in strip width laminee

摘要

The change in the mill modulus of the stand of a rolling mill due to the particular strip width of a run strip of material is taken into account by reference to the unloaded mill modulus of the stand and a desired roll gap opening is calculated on the basis of an error relative to the actual roll gap opening in order to achieve a desired strip thickness setting.
