Abstract
PURPOSE: To remove the influence of the slip between the pinch roll surface and the strip on purpose to improve the accuracy of operation on the coil diameter, by installing two units of the sensor at the adequate positions in the strip.
CONSTITUTION: In the controlling system for the rolling mill, a certain point of the strip 8 is detected by the sensor S1, and the output pulse of the coiler-pulse-generator PG1 is counted using the output of the sensor S1 as the interruption signal, and the number of rotation of the coiler 7 is checked. This procedure is continued until the sensor S2 detectos the same point of the strip 8; the total number of rotation, from the detection by the sensor S1 to the detection by the sensor S2, is taken as N, and the thickness of the strip is given as H; and then, from the formulas I, II, are operated the coil diameter D0 of the coiler for the moment of detection by the sensor S1, and the coil diameter Dx for the moment of detection by the sensor S2. According to this method, the highly accurate, highly reliable coil diameter is operated being free from the bad influence of the slip
