摘要 |
<p>A method for producing molten metal by the reduction and melting of raw materials in a submerged arc type electric furnace includes at least one electrode, where substantial amounts of slag are generated so that the electric furnace contains a bath of molten metal covered with a thick layer of molten slag having a mass per unit area of at least 1000 kg/m<2>. The thick layer of molten slag is made to foam locally around the at least one electrode so as to create around the electrode a local layer of foaming slag in which the density of the slag is at least 50 per cent lower than in the rest of the electric furnace.</p> |
