The present invention relates to a method and apparatus for feeding a reaction gas, advantageously oxygen or air, or a mixture thereof, into a smelting furnace so that the cross-sectional area through which the reaction gas is fed can be adjusted. Thus the velocity of the gas discharged into the smelting furnace can be maintained sufficiently high even when the quantity and quality of the gas varies.
Cette invention concerne une méthode et une tuyère d'injection d'un gaz, préférablement de l'oxygène ou de l'air ou un mélange des deux, dans un four de fusion, caractérisées par la possibilité de régler la section de la tuyère d'injection. Ainsi, la vitesse d'écoulement du gaz dirigé dans le four de fusion peut être maintenue à une valeur relativement élevée même quand le volume de gaz disponible et sa qualité varient.
