Abstract (en)
[origin: EP0620062A1] The (ingot) mould according to the invention is provided with a thermo-insulating hot top (2) made from rigid refractory material implanted on the tube element made from chilled copper (1) and means (8, 18, 12, 12, 13, 10) are provided for injecting, through the wall, a pressurised gas which emerges in the casting space 3 in the form of anular jets (streams) which cut through any solidification skin (crust) already formed by the cast metal (4) in contact with the refractory hot top (2). The invention makes it possible to distance the meniscus (7) from the solidification front of the cast metal in the copper element by eliminating the risks of incipient solidification between the two. <IMAGE>
