Abstract

Apparatus and method for measuring thickness of sheet material, particularly in a rolling mill, and controlling a roll stand. An X-ray florescence analyzer for determining the components of the sheet material, a radiation thickness gauge with a calibration system for gauging material of varying composition, and a computer for calculating a calibration signal for the thickness gauge based on the output of the analyzer, with the thickness gauge output providing a measure of the thickness of the sheet material at the gauge and a control signal for controlling the roll stand.
