Abstract

1,091,484. Automatic control of rolling mills. BRITISH IRON & STEEL RESEARCH ASSOCIATION. June 4, 1965 [June 11, 1964], No.24255/64. Heading G3R. To control thickness of material rolled in a reversing mill, e.g. for hot plate finishing, measurements are made of ingoing thickness, width and temperature and corresponding signals fed to a digital computer with other signals chosen manually or by punched card to correspond to pass characteristics, such as speed and draft, and mill characteristics, such as deformed roll radius. The computer operates according to formulae given in the spec. to predict the necessary load on the mill rolls which it then produces by control of the roll screw-down motors. During the first pass the computer compares the actual roll load, as determined by strain gauges, with that predicted, and any error is caused to alter the gain of the control system so that more accurate prediction is made for the next pass which, being in the reverse direction, utilizes measurements of thickness, width and temperature on the other side of the rolls. The signals representing mill characteristics, which are determined by trial passes, are revised periodically, e.g. for each working shift.
