DETECTING METHOD FOR ROLLSIGMA ECCENTRICITY IN ROLLING MILL

摘要

PURPOSE:To exactly detect the roll's eccentricity and to control the roll's eccentricity at high accuracy, by detecting the roll's eccetricity under the OFF-rolling condition correspondingly to the actual rolling condition. CONSTITUTION:The output of the load cell 4 for detecting the rolling load is inputted to the computer 17 through the operator 14, the sampler 15 and the A/D converter 16. The timing of the sampler 15 is taken according to the pulse given by the pulse generator 5; the output of the load cell 4 is inputted to the counter 18 and is counted; and the turning angle of the upper backup roll 2 is detected. The output of the pulse generator 5 is inputted to the computer 17; and the output of the A/D converter 16 is read in the computer 17 synchronously to above pulse; and the time for one turn of the upper backup roll 2 is detected by the counter 20. This time is inputted to the computer 17, and the amount of necessary adjustment for the roll's eccentricity is computed and is inputted to the operator 12 through the A/D converter 22; and the roll's eccentricity is controlled by making and breaking the switch 23.
