Description

ABSTRACT Company called: DAUSSAN ET COMPAGNIE "Stopper for retaining slag and process for implementation and manufacture thereof" (An invention of: Jean-Charles DAUSSAN Gérard DAUSSAN and André DAUSSAN) The stopper (1) is intended to automatically stop the orifice (14) of the pouring hole (11) of a metal- lurgical container (8) at the end of pouring of liquid metal (12) before the passage of slag (13). It principally comprises an external envelope in a refractory insulating material which is capable of sintering inside the metallurgical container (8), and composed of inorganic refractory particles embedded in a binder and a heavy core (6) intended to give the stopper (1) a density such that it floats on the liquid metal (12) and is sufficiently submerged in the metal (12) in order to stop the orifice (14) of the pouring hole (11) before the passage of slag (13). Application to the pouring of liquid metals. See Figure 2.
