<p>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. <IMAGE></p> |
