    Abstract: 1,208,236. Continuous casting machines and processes. CONCAST A.G. and SCHLOEMANN A.G. 25 April, 1969 [29 April, 1968; 21 May, 1968], No. 21363/69. Heading B3F. In a continuous casting process where melt is poured into a tubular mould which is blocked by a starter head having a projection about which the melt solidifies, the casting is withdrawn from the mould by the starter head and separated from the starter head by tilting or rotating the longitudinal axis of the starter head out of alignment with respect to the longitudinal casting axis. In the Figure, the starter head 3 of a starter bar plugs a mould 1 and is connected to a starter bar by a hinge 49. The head 3 has top faces (16), 17 inclined with respect to the casing axis and a recess which terminates at an inclined plane 22 extending into the head along the mould side 6. The mould is sealed with asbestos fillets 26. Within the recess the starter head is provided with a semi-cylindrical projection 5. The melt then solidifies in the starter head in the form of a hook, and separation of the casting and starter head is effected by pivoting the starter head about a point 27.

    Abstract: A method of and apparatus for operating a multiple-roll machine, especially a multiple-roll withdrawing machine or a multiple-roll combination withdrawing and straightening machine in a continuous casting plant, wherein a casting and a dummy bar are passed between pairs of rolls. By means of each pair of rolls there is applied to the casting and the dummy bar as they pass therebetween, the requisite contact pressure for generating the necessary traction or withdrawal force. When the thickness of the casting falls below a prescribed thickness there is applied to the casting only a contact pressure of a magnitude required for traction and when the thickness of the casting exceeds the prescribed thickness the contact pressure is increased to a greater value calculated to again reduce the thickness of the casting to the prescribed thickness.

    Abstract: 1,115,395. Tundishes. CONCAST A.G. 9 March, 1966 [9 March, 1965], No. 10447/66. Heading F4B. [Also in Division B3] Apparatus for changing the position of a jet of molten metal issuing from a tundish 1 in a continuous casting machine comprises a slidable plug 7 with aperture 8 and a closing element 9 with aperture 10 both in steel frames mounted in a guide 12 slidable by a hand wheel 17, a screwed portion 18 of whose spindle engages half nuts 20, 21 connected by levers 24 and 25, respectively, with the guide 12 and the element 9. Element 7 may incorporate an induction heating system to avoid freezing of metal on its top surface. In a modification, Fig. 3 (not shown), the position of elements 7 and 9 is reversed, and another modification, Figs. 4 and 5 (not shown), allows of sliding movement in two directions at right angles to one another. The sliding plug may incorporate a downwardlyextending spout, Figs. 7 and 8 (not shown), or, using a stopper nozzle for the tundish, the discharge may be through an inclined bore in a sleeve rotatably mounted axially of the tundish discharge spout, Fig. 9 (not shown). The rotatably mounted sleeve incorporates a plug rotatable therein about a horizontal axis and formed with a cross-bore, whereby the combined rotary movements allow of a universal movement for the jet of metal, Figs. 10 and 11 (not shown).
