Abstract: 982,981. Continuous casting - machines. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 27, 1961 [Feb. 25, 1960], No. 7063/61. Heading B3F. In a continuous casting process the dummy ingot used when starting is automatically detached from the cast ingot when this emerges from the mould, and then the cast ingot is automatically brought progressively and continuously into a substantially horizontal position and cut. In one embodiment a movable part 6 of a shoot 5 is held in the position shown in Fig. 1, by the dummy ingot 4. During withdrawal the dummy 4 is detached by a device 2 and falls into a well 12, allowing the portion 6 to take up the position 6<SP>1</SP>, Fig. 2, and guide the casting 4<SP>1</SP> into the straightening rolls 11. In a modification, Fig. 4, the shoot has a sliding portion 6. In a further modification, Figs. 6, 7, the dummy passes through the open jaws of a gripper 16 which are then closed on to the end of the casting when a photo-electric cell 18 reacts thereto. The gripper then carries the end of the casting to the straightening rolls 11, where it is gripped by guide rolls 22, a relay 23 causing the jaws 16 to open. The straightening rolls 11 lead to a cutting-up device. The closing of the jaws 16 may be actuated by relays triggered by the fall of the dummy into the well 12, or by the device which disconnects it from the ingot, instead of by the cell 18.
