摘要
The lowermost end of a filling tube which extends through a protective top into a vessel containing a melt includes a support flange which mounts a dip container inside the vessel. The dip container is shaped to define an internal reaction chamber below the lowermost end of the filling tube and to provide communication between the internal reaction chamber and the melt. It includes a basket-shaped metal container which is attached to the support flange and an outer sheath formed of a reinforcing material-containing refractory, the outer sheath covering both the metal container and the filling tube up to a point near the protective top so as to leave an expansion joint between it and each of the metal containers, the filling tube and the protective top.
