More Information
Summary:Furnace (1) for melting metal-bearing substances and/or smelting of liquid metal (4), of the type in which the said metal (4) has above it a layer of slag (5) capable of being affected by a "foaming" phenomenon, characterised in that a side wall of the said furnace has an orifice (17) emerging into an adjacent trough (22) capped with a vault (25), it being possible for the said trough (22) to collect by overflowing through the said orifice (17) a portion of the said slag (5) when the said foaming phenomenon takes on proportions resulting in a risk of damage to the said furnace (1). The invention also relates to a process for smelting liquid metal, employing such a furnace. L'invention concerne un four (1) de fusion de matières métallifères et/ou d'élaboration de métal liquide (4) du type dans lequel ledit métal (4) est surmonté par une couche de laitier (5) susceptible d'être affectée par un phénomène de "moussage", caractérisé en ce qu'une paroi latérale dudit four comporte un orifice (17) débouchant dans un bac adjacent (22) coiffé d'une voûte (25), ledit bac (22) pouvant recueillir par débordement à travers ledit orifice (17) une partie dudit laitier (5) lorsque ledit phénomène de moussage prend des proportions risquant d'entraîner des dommages sur ledit four (1). L'invention concerne également un procédé d'élaboration de métal liquide utilisant un tel four.
