1. Anordning för bläsning av gas samt eventuellt finfördelat fastmaterial inne i en metallurgisk smälta, vilken anordning om-fattar ett bläsrör (1) med en inloppsöppning vid den ena ändan, vilken öppning är avsedd att anslutas tili en gaskälla och en ut-loppsöppning vid den motsatta ändan, avsedd att sänkas under smäl-tans yta för att bläsa gas inne i smältan, en blasröret omgivande kylningsanordning, som har vid den mot inloppsöppningen vända ändan en inlopps- (4) och utloppsöppning (6) för kyIningsmedlet, samt en mantel (7) av värmeisolerande keramiskt material, omgivande ätminstone den nedre delen av kylningsanordningen, kanne-t e c k n a d av att det förefinns vid bläsrörets utloppsöppning ett Laval-munstycke (9), som bildar en vinkel med blasröret och som sträcker sig genom den värmeisolerande mäntein (7), att kylningsanordningen bildas av kylningsrör (4, 6), med en liten diameter och väsentligen parallella med blasröret (1) och vilkas inloppsöppning är avsedd att anslutas tili en sadan källa av gas-vätskeblandning, som snabbt förängas i kylningsanordningen och mäntein (7) omgivits med en holk (8) av grafit eller kiselkarbid, vilken holk är ätminstone av sadan tjocklek, att den skyddar det keramiska materialet (7), när anordningen sänks inne i smältan sä, att det keramiska materialet ernär smältans temperatur Läng-sammare än holken och sintras innan holken slitats.
2. Anordning enligt patentkravet 1, kännetecknad av att gasbläsröret ställts i en sadan ställning i den metallur-giska smältan, att reaktionsmedlet avlägsnas frän gasbläsröret horisontellt i förhällande tili reaktionsmedelröret (1).
3. Anordning enligt patentkravet 1 eller 2, kännetecknad av att Laval-munstycket (9) av gasbläsröret är av sintrad metallblandning, som innehäller utöver krom 2-5 vikt-% koboit.
4. Anordning enligt patentkraven 1-3, kännetecknad av att kylningsmedelrören bestär av inloppsrör (2a) för kylnings-medlet, viLka är vid sinä övrc ändar anslutade tili en gemensam
