Abstract

1458973 Automatic control GEC-ELLIOTT AUTOMATION Ltd 23 Aug 1974 [23 Aug 1973] 40000/73 Heading G3N The rolling of strip material in a rolling mill is automatically controlled in response to calculations deriving the ideal roll force on a stand which will give the nose of the strip material a shape threadable into a subsequent stand or within predetermined limits of badness. As shown, a digital computer 22 is programmed to provide, or is fed from punched-tape, a rolling schedule in ablock 100. The schedule is fed to a calculator block 101, in which the roll force occurring on the nose of a strip is determined, and to a calculator block 102 which determines the thermal camber to be used in determining the zero shape roll force in a calculator block 103. The outputs of blocks 101, 103 are compared in a comparator 104 and the output used to calculate the jack force settings and gauge changes in a block 105 which is then used by a programmer 106 to apply these settings to the mill during threading and subsequently to remove them as the strip passes through the mill. The calculations to be carried out in the blocks 101-105 are set out in detail in the Specification.
