Patent

CA 2179917

An annular nozzle for an oxygen lance, e.g. an oxygen lance for blowing steel in a converter, gives an annular hot spot on the liquid steel in the converter . When exiting the nozzle, the annular jet has disruptions that result in ambient atmosphere being sucked in towards the centre of the annular jet. Thus, a sub-pressure is prevented which would otherwise prevent the jet from diverging conically. In one embodiment, the nozzle can be switched during a blowing operation between forming a tight jet and forming a diverging jet.

Tuyère annulaire destinée à une lance à oxygène telle qu'une lance à oxygène utilisée pour souffler de l'acier dans un convertisseur, cette tuyère annulaire produisant un point chaud annulaire sur l'acier liquide présent dans le convertisseur. Lorsqu'il sort de la tuyère, le jet annulaire présente des interruptions qui ont pour effet d'aspirer l'atmosphère ambiante vers le centre dudit jet annulaire. Ceci empêche donc une sous-pression de se développer qui empêcherait le jet de diverger de manière conique. Dans une forme de réalisation, on peut commuter la tuyère pendant une opération de soufflage pour former un jet serré ou un jet divergent.
