Title
(EN) REDUCTANT ADDITION IN A CHANNEL INDUCTION FURNACE
(FR) AJOUT D'UN RÉDUCTEUR DANS UN FOUR À INDUCTION À CANAL
Abstract
(EN)
A method of operating a channel induction furnace to process a feed material and obtain therefrom at least one of a molten metal product, a vapor phase metal product and a slag product. A molten metal bath is maintained in the channel induction furnace and the method includes adding a reductant such as carbon or a carbon containing material directly into the molten metal bath independently of the feed material.
(FR)
L'invention concerne un procédé d'utilisation d'un four à induction à canal pour traiter un matériau d'alimentation et obtenir à partir de celui-ci un produit métallique fondu et/ou un produit métallique en phase vapeur et/ou un produit de laitier. Un bain de métal fondu est maintenu dans le four à induction à canal et le procédé comprend l'ajout d'un réducteur tel que du carbone ou un matériau contenant du carbone directement dans le bain de métal fondu, indépendamment du matériau d'alimentation.
