Abstract

1321116 Automatic control of rolling ISHIKAWAJIMA-HARIMA JUKOGYO KK 23 Nov 1970 [20 March 1970] 55527/70 Heading G3R In a rolling mill, analogue measurements of the force on the working or back-up rolls are made periodically during each revolution and converted into digital signals. The phase position and magnitude of any eccentricity of the rolls, calculated from the digital signals and their mean values under the control of pulses produced by roll rotation, are converted to analogue form, stored and applied to control roll force so that eccentricity is compensated for and rolled material of uniform thickness in a longitudinal direction is produced.
