Abstract

A process of protecting a tuyere of a refining converter having a double or multiple feed of which one, which may be the central feed, is pure oxygen, the process comprising feeding preferably a peripheral conduit with a viscous, a pasty, or powdery and compressed material containing carbon to protect the nose of the tuyere against wear by hot corrosion.
