Abstract

A rolling mill facility includes a single or plural rolling mills having a pair of top and bottom work rolls and that roll strip steel and strip shape detecting devices installed at least on one side of the inlet and outlet sides of the rolling mill. The strip shape detecting devices consist of a single roller on which the metal strip gets wound and at least two bearing boxes one side or four bearing boxes on both sides with the bearing boxes supporting the roller in a free-to-rotate manner and at least two load cells on one side or four load cells on both sides for measuring the supporting load of each of the bearing boxes. From the load values measured by the load cells, the tension distribution of the strip is computed and that tension distribution is converted into the strip shape of the strip.
