Abstract

Procédé de fabrication d'un produit à base de ferro-alliage à l'état de fusion dans un four de fusion, chargé de briquettes essentiellement composées de fer métallisé, de granules d'un oxyde de métal alliant, d'une source de carbone, telle que du coke menu, et d'un laint, tel qu'un mélange d'hydroxyde de calcium et de molasse, la réduction de cet oxyde de métal alliant en l'élément métallisé correspondant étant provoquée par la combustion d'une matière à base de carbone, par laquelle est également chauffée la charge pour former un ferro-alliage à l'état de fusion. Des fondants et formateurs de scories sont, le cas échéant, également introduits dans le four.Method for manufacturing a ferro-alloy product in the molten state in a melting furnace, charged with briquettes essentially composed of metallized iron, granules of an alloying metal oxide, of a carbon source , such as small coke, and a coat, such as a mixture of calcium hydroxide and molasse, the reduction of this metal oxide combining in the corresponding metallized element being caused by the combustion of a material based on carbon, by which the charge is also heated to form a ferro-alloy in the molten state. Fondants and slag formers are also introduced into the furnace, if necessary.
