NEW ROLL ECCENTRICITY CONTROL SYSTEM (MARECS) FOR ROLLING MILL.

Roll eccentricity control is used to prevent the periodic variations in strip gage caused by several tens of microns of geometrical eccentricity between the bearing center of the backup roll and the center of the roll barrel. This paper presents an outline, principle, and test results of a newly developed automatic roll eccentricity control system. The accuracy of waveform detection by this system and its control effect have been confirmed by the tests carried out using an analog computer simulating the actual rolling mill and the actual roll eccentricity control system.
