Abstract

1316786 Rolling mills WEAN UNITED Inc 11 June 1970 [13 June 1969] 28266/70 Headings B3E and B3M Metal strip is passed between a pair of rolls so that it bends alternately around part of one roll and then part of the other, at least one of the rolls having its crown varied such that the tension across the strip is controlled and the resulting strip is of improved flatness. The strip is compressed as it passes between the rolls in order to reduce its thickness. In the embodiment shown, a pair of rolls 14, 15 is supported by backing rolls 12, 13 and the rolls are heated by water sprays 16 and 17 to control their crown. The sprays, Fig. 2, are spaced along the lengths of the rolls and are supplied, by valves 18, 19, and 21, with water from relatively hot and cold sources 25 and 24. The distribution and temperature of the water, and hence the crown of the rolls, is controlled by the valves. Alternatively the rolls 14 and 15 may be bent to impart a desired degree of crown to them.
