Abstract

A találmány tárgya tűzálló dugó vagy tégla gáz injektálásához olvadtfémbe egy, az olvadt fémmel érintkező felületen (11) át, valaminteljárás a dugó vagy tégla előállítására. A dugó vagy tégla áll a) egyporózus tűzálló testből (2), amely lényegében - az olvadt fémmelérintkező felület (11) kivételével - egy lényegében nem porózustesttel (9) van burkolva, valamint b) egy gázvezető eszközből (3elosztócső, 5 tömítőcement vagy -habarcs), amely a gázt egygázforrásból a porózus testhez (2) szállítja. A találmány értelmében anem porózus test (9) tűzálló anyagból készül, tovább a porózus test(2) és a nem porózus test (9) együtt van sajtolva. A találmányszerinti dugó vagy tégla arra alkalmazható, hogy apró buborékokathatékonyan és megbízhatóan injektáljon egy olvadt fémfürdőbe. ÓThe subject of the invention is a refractory plug or brick for injecting gas into molten metal through a surface (11) in contact with the molten metal, as well as a method for producing the plug or brick. The plug or brick consists of a) a single-porous refractory body (2), which is essentially - with the exception of the molten metal contact surface (11) - covered with an essentially non-porous body (9), and b) a gas-conducting device (3 distribution pipe, 5 sealing cement or mortar ), which transports the gas from a single gas source to the porous body (2). According to the invention, the porous body (9) is made of refractory material, and the porous body (2) and the non-porous body (9) are pressed together. The plug or brick of the invention can be used to efficiently and reliably inject tiny bubbles into a molten metal bath. HE
