More Information
Summary:The invention relates to a furnace (1) for melting metal-bearing substances and/or production of liquid metal (4) of the type in which said metal (4) has above it a layer of slag (5) liable to be affected by a "foaming" phenomenon, in which a side wall of said furnace comprises an orifice (17) opening into an adjacent tank (22) capped with a vault (25), said tank (22) being capable of collecting a proportion of said slag (5) by overflowing through said orifice (17) when said foaming phenomenon takes on proportions that risk causing damage to said furnace (1). The invention also relates to a process for the production of liquid metal employing such a furnace.
