摘要
A nozzle (3) is claimed for introducing liquid metal into the mould (10) of a continuous casting machine, of the type that comprises a shaft (4) of which the upper end is designed to be connected by some means of fixing (6,7) to the outlet nozzle (1) of a hot metal ladle and the lower end of which is connected to a terminal part of the nozzle (3) equipped with apertures (19, 20, 20') designed to distribute the liquid metal in the casting space (13) defined by the mould (10). This terminal part of the nozzle (3) incorporates, in its upper zone, at least one aperture (17) designed to allow the reheating of the interior of the terminal part by some means of heating such as a burner (32, 32'). The installation for the continuous casting of metal products using this nozzle (3) is also claimed and is of the type incorporating a bottomless mould (10) with energetically cooled walls (11, 11' ,12, 12') defining a casting space (13) and a nozzle (3) of refractory material connected to a vessel containing the liquid metal, the lower end of the nozzle feeding this liquid metal into the casting space (13). This installation can be a classical slab casting machine or a casting machine with rolls for casting thin strip.
