摘要： A ROLLING MILL HAS A GAGEMETER CONTROL ON SUBSTANTIALLY EVERY MILL STAND. AN X-RAY GAGE DEVIATION SIGNAL IS FED THROUGH AN ISOLATOR UNIT WHICH PROVIDES A WIDE DEAD-BAND WITHIN THE GAGE TOLERANCE FOR A PARTICULAR ORDER. IF THE GAGE DEVIATION SIGNAL EXCEEDS THE WIDTH OF THE DEAD-BAND THE DEVIATION SIGNAL IS INTEGRATED IN A HIGH GAIN INTEGRATOR AND USED TO CHANGE THE SET POINT OF THE GAGEMETERS ON EACH GAGEMETER CONTROLLED MILL STAND UNTIL THE X-RAY GAGE DEVIATION RETURNS WITHIN THE DEAD-BAND PROVIDED BY THE ISOLATOR UNIT.
