CA 2217329

A furnace plant which comprises at least one furnace vessel (2) with side walls (21) and a bottom (22) and at least one heat source (31) which by radiation and convection heats molten metal and/or solid metal present in said furnace vessel. At least one two- or multiphase electromagnetic side stirrer (4, 24, 24a, 24b, 24c, 34, 34a, 34b) is arranged in or near the wall (21) of the furnace vessel to act through said wall and apply a stirrer field to the molten metal. The side stirrer comprises at least two phase windings arranged around an iron core which has a vertical extent, H, which essentially covers the region, D max, between the bottom and the upper surface of the molten metal at a maximum bath depth used in the furnace vessel. The side stirrer is arranged with a pole pitch.tau. which exceeds twice the distance from the iron core to the molten metal, .tau. > 2 d w.

L'invention se rapporte à une installation de four qui comprend au moins une cuve (2) pourvue de parois latérales (21) et d'un fond (22), et au moins une source de chaleur (31) qui chauffe, par radiation et convection, le métal fondu et/ou le métal solide se trouvant dans cette cuve. Au moins un agitateur-mélangeur latéral (4, 24, 24a, 24b, 24c, 34, 34a, 34b) électromagnétique, diphasé ou multiphasé, est aménagé dans ou à proximité de la paroi (21) de la cuve du four et passe par cette paroi pour appliquer un champ magnétique sur le métal fondu. L'agitateur-mélangeur latéral comprend au moins deux enroulements diphasés, disposés autour d'un noyau de fer présentant une zone verticale H qui recouvre principalement la région Dmax entre la surface inférieure et supérieure du métal fondu à une profondeur de bain maximum de la cuve. L'agitateur-mélangeur présente un écartement polaire tau qui dépasse deux fois la distance allant du noyau de fer au métal fondu, tau > 2 dw.
