1329008 Continuous casting COMPAGNIE PECHINEY 24 Sept 1970 [26 Sept 1969] 45521/70 Heading B3F At least four mould-spraying jackets 211, 212, 311, 312 are supported on a frame 11, 12, 13 to form a framework for receiving and supporting at least one mould 1, Fig. 4, (to be cooled by water-sprays from holes or a slot 2111, 3121 in each jacket); jackets 211, 212 bridge the frame members 11, 12 to which they are fixed at a spacing determined by the other jackets 311, 312 which, in turn, bridge them at a selected spacing according to the chosen mould size, each jacket being supplied from at least one manifold 40, 50 by a flexible coupling 611, 612, 613, 711, 712 or 713 through an individual valve 811, 812, &c. for independent flow control. The flexible couplings 611, 713 to the ends of a cross jacket 211 connect through valves 811, 913 to a slit tube portion 2115, Fig. 4, of the jacket and the water passes around a baffle 2116 to the spray outlets or outlet 2111. The ends of the jacket 211 are of U-form to embrace the frame members 12, 13 and be bolted to them. The shorter jackets 311, 312, of which there would be a selection of different lengths, are closed at the ends and supplied with water at the middle. The pipes 40, 50 of the manifold may be supplied with water independently. As many as ten castings may be performed simultaneously, Fig. 6 (not shown) and, by varying the spacing of the shorter jackets with appropriate moulds, different sizes of casting may be produced. An assembly of bottoms (191, 194) for initially closing the moulds is mounted on a common lowerable support (190).
