Abstract
A gas lance made of a fireproof material, having an entry surface and an exit surface, having channels having slit-shaped cross-section, which comprise an entry slit and an exit slit. In order to provide a gas lance in which the gas exits in such a manner that a good thorough mixing of the melt is achieved and a simple penetration of the melt by the gas is avoided, the projection of the exit slit of a channel onto the entry surface may be offset in relation to the entry slit of the channel.
Claims9
A gas lance formed of a fire proof material, said lance having a truncated cone-shape and including:
- an entry surface, and exit surface, and plural channels extending continuously therebetween;
- the channels forming slits in transverse cross-section;
- the channels having an entry slit disposed in entry surface and an exit slit disposed in the exit surface;
- the slit-shaped channel transverse cross sections are oriented approximately radially from a central longitudinal axis of the lance, projections of the exit slits onto the entry surface are offset relative to the entry slits.
