Abstract (en)
[origin: EP0589762A1] Casting tube for metal, including a body (22) made from refractory material, in which a flow channel (24) for the molten metal is provided. The tube includes an annular chamber (32) provided in the body (22), arranged around the channel (24) in the vicinity of the periphery of this channel, extending virtually over the entire length of the channel, connected to means (34) for creating a reduced pressure (vacuum) with respect to the environment of the tube. The chamber (32) forms a screen to the migration of gaseous products, such as carbon monoxide, towards the channel. The tube may also include a sleeve (30) made from refractory material interposed between the periphery of the channel (24) and the chamber (32). The tube is used preferably for the continuous casting of steel. <IMAGE>
