Device of refractory porous material for blowing gas into a bath of liquid metal |
摘要 |
A device for blowing gas under pressure into a bath of liquid metal comprises a mass of refractory material which is porous at least at an inner portion thereof and placed into a metallic container constituted by an outer metallic envelope closed at one of the ends thereof by a bottom member through a central portion of which a conduit extends for feeding a gas under pressure to the porous inner portion of the mass. A deflector is provided fluid-tightly connected to the bottom inwardly of the envelope in which the wall of the deflector extends parallel to that of the envelope but short of the length of the latter. This permits, on the one hand, to avoid penetration of liquid metal between the envelope and the mass of refractory material to a point where it would block the gas feeding conduit and, on the other hand, to canalize the gas through the porous portion of the mass. The present invention relates likewise to a method of making the above device.
