Abstract

1492578 Cooling rolled strip GENERAL ELECTRIC CO 11 Dec 1974 [11 Dec 19731 53579/74 Heading B3M A rolled strip is cooled at a predetermined rate as it passes from the finishing train 22 of a rolling mill to a coiler 26 by controlling the number and distribution of sprays 32 which act on the strip. Since the sprays each produce a constant output, their cooling effect on the strip is controlled by regulating the number and positions of the sprays which are operative at any moment. A computer 40 selectively makes them operative according to the inputs from pyrometers 42, 44 and 46 and a pulse tachometer 54 (indicating strip speed). The pyrometer 42 serves to indicate an initial spray pattern, whereas the pyrometers 44 and 46 provide feedback signals to generate the desired strip cooling rate and coiling temperature.
