Abstract

1280821 Rolling DAVY & UNITED ENG CO Ltd 21 Aug 1969 [24 May 1968] 24840/68 Heading B3M [Also in Division G3] A multi-stand rolling mill comprises stands F1-F6 each having work-rolls, back-up rolls and means for setting screw-down, stands F1, F3, F6 have screw position control and load sensing equipment SP and L and stands F2, F4, F5 have automatic gauge control equipment AGC, data concerning the dimensions, temperature and material of a workpiece are supplied to a computer and a rolling schedule is calculated to roll the workpiece to a desired final gauge, calculating the rolling load P and torque G of each stand and repeating the calculations iteratively to produce a final schedule within mill constraints and which makes the optimum use of the power available to drive the mill. Formulae are given for calculating P and G. A pyrometer P checks the actual temperature of an incoming workpiece and the final gauge is monitored by means of an X-ray thickness gauge R. If the required final gauge cannot be met without exceeding mill constraints a thicker gauge is selected automatically by the computer and a schedule calculated. Workpieces which arrive at the mill at a higher than specified temperature are held on a delay table D.T. cooler workpieces are run through the mill at higher speeds.
