Abstract

1,209,030. Electric correspondence control systems. UNITED ENG. & FOUNDRY CO. Dec.8, 1967 [Dec.15, 1966], No.56166/66. Heading G1N. In a strip rolling mill using plain cylindrical rollers 14, Fig. 1, wherein the initial gap between the work rollers is set up by screws 15, 16 and a bending force F is applied by piston-cylinder assemblies 17, 18 to the back-up rollers 13 to produce a crown on the work rollers to produce minimum deviation of thickness across the width of the strip, the relationship between the bending force, the physical characteristics of the machine and the strip thickness is calculated, and the bending force automatically maintained at the value appropriate to the desired strip thickness. A computer unit 26, Fig.3, set up in accordance with the physical constants of the rolling mill stand is fed with electrical signals representing (a) the initial roll gap, measured by potentiometer 23, (b) the total rolling force P, measured by load cell 21, (c) the bending force F, measured by pressure transducer 22, (d) the desired strip thickness t<SP>1</SP>, measured by potentiometer 25. The output signal e represents the deviation from the calculated relationship, and is fed to control valve 29 to control the bending force F until the deviation signal is zero. The resulting total rolling force and mill crown is said to produce strip of the desired thickness with minimum deviation of thickness longitudinally and transversely of the strip.
