<p>An apparatus (1) for injecting gases or fluids in general and particulates, particularly for injecting oxygen, in furnaces for the production of steel. The apparatus comprises a structure (2) for supporting at least one injection lance (3), means for moving the injection lance along a substantially vertical direction, and first means for the oscillation of the lance on a substantially vertical plane to vary the angle of impact of the jet delivered by the injection lance relative to a horizontal plane.</p> |
