摘要

In a rolling mill facility having a strip shape detection equipment, making it possible to measure the strip shape of metal strip after rolling easily and with a simple construction. In a rolling mill facility consisting of a single or plural rolling mills 4 having a pair of top and bottom work rolls 2 and 3 that roll strip steel 1 and strip shape detecting devices 5 and 6 installed at least on one side of the inlet and outlet sides of the rolling mill 4, said strip shape detecting devices 5 and 6 consist of a single roller 14 on which the metal strip 1 gets wound, and at least two bearing boxes 9A and 10A on one side or four bearing boxes on both sides with said bearing boxes 9A and 10A supporting the roller in a free-to-rotate manner, and at least two load cells 11A and 12A on one side or four load cells on both sides for measuring the supporting load of each of the bearing boxes 9A and 10A. From the load values measured by these load cells 11A and 12A, the tension distribution of the strip 1 is computed, and that tension distribution is converted into the strip shape of the strip .
