摘要

Injection lance nose comprises a principal metal tube (1) and at least two tuyeres (2) fixed to the injection tube, the tuyeres being connected to the lower part of the canal of the injection tube and emerging from the lower wall of the nose. Each tuyere (2) is surrounded by a protection tube (5) which is also fixed to the injection tube (1). The principal metal tube (1) of the nose may be an extension of the injection tube of the lance or it may be screwed onto the injection tube.
