APPARATUS FOR MEASURING THE ROLLED PLATE AND CAMBER CONTROL METHOD USING THE APPARATUS

摘要

A contact measuring apparatus for a rolled material and a camber control method using the apparatus are provided to minimize misalignment of the rolled material and camber occurring on the rolling pass. A contact measuring apparatus for a rolled material comprises a rotator(10) which is arranged in one or both of the entry and exit of the rolling mill and forms a height difference when rotating, and a plurality of contact measuring units(30) which are arranged in the rotator in the longitudinal direction and contact with the bottom surface of the material when the rotator rotates. The rotator includes a rotary shaft(12) arranged between rolled material transfer rolls(120) and a rotation roll(14).
