Verfahren zum Walzen von bandfoermigem oder blechfoermigem Material

摘要

Strip or plate material being rolled under symmetrical rolling conditions is simultaneously corrected for gauge and shape errors in a single integrated gauge and shape control system, by detecting its gauge and shape upon leaving the rolling mill; expressing detected shape as a defined combination of different curves and deriving defined error signals from coefficients of the curves; deriving an error signal from detected gauge; translating said error signals into defined control signals; and feeding each control signal to a respective one of a plurality of different rolling mill control means.
