Process in which an inert gas and oil are injected during the flow of molten metal in the pipe at the joint between the two refractory pieces in order to prevent atmospheric gases from entering the pipe at the joint. The process has the advantage of sealing leaks at the joint, reducing inert gas consumption, and ensuring the quality of the molten metal, since there is no deterioration produced by the inert gas.

Procédé dans lequel, pendant l'écoulement du métal liquide dans ce conduit, on injecte un gaz inerte et de l'huile, au niveau du plan de joint entre les deux pièces réfractaires de manière à éviter l'introduction de gaz provenantde l'atmosphère dans ce conduit au niveau du plan de joint. Avantages: colmatage des fuites au niveau du plan de joint, diminution de la consommation de gaz inerte, absence de dégradation de la qualité du métal liquide par le gaz inerte.
