Abstract
1516403 Monitoring steel plate BRITISH STEEL CORP 2 July 1976 [3 April 1975] 13712/75 Heading G1N The thickness of steel plate produced in a rolling mill, as determined by the screwdown position indicator 11, and its length, as determined by the number of revolutions of one of the rolls, measured by a pulse generator 12, in association with its known diameter, are compared with a target thickness at 17 and a target length at 18. Strain gauge load cells 10 attached to the mill housing establish when the plate enters and leaves the rolls, and modify at 13 the screwdown position indication in accordance with the mill elasticity, to establish the actual plate thickness. If h 0 , h 1 are the plate thicknesses for successive passes and d the circumference of the roll, the actual length l 1 of the strip is given by where k is a known constant for the particular mill. These values of l 1 and h 1 are utilized in the formula l n À h n = l 1 À h 1 to determine the length l n after n passes for a target thickness H or the thickness h n for a target length L. If the original targets H, L are not attainable more appropriate final values are established for use in the rolling control system 21.
