The invention relates to a metallurgical oven, comprising a vessel (10), a cover (20) for the vessel, a charging device (30) for charging items which are to be melted to said vessel. Said charging device comprises a rotatable retaining means (31) and a volume (C) for receiving charging items, and a projection (40) which is provided in charging opening (42) and which is arranged on the cover (20) or on the vessel (10). The oven has a maximum filling level (H2), the rotatable retaining means is pivoted for charging into the projection, the vessel, the cover, the charging device, the retaining element and the projection are dimensioned in such a way that the pivoting range of the retaining means is higher than the maximum filling level (H2). The invention is characterised in that the charging device comprises at least two self-supporting material baskets (32) which can be positioned in a removable manner above the projection (40) comprising respectively an inner chamber which can be closed on the lower side of the material basket (32) by the retaining means (31) and also a volume (C) for receiving the charging items and an interchangeable device (33) provided for interchanging and positioning the material basket (32).

Four métallurgique qui comporte une cuve (10), un couvercle (20) pour ladite cuve, un dispositif de chargement (30) destiné au chargement de matière à faire fondre dans la cuve, qui possède un moyen de retenue pivotant (31) et un volume (C) destiné à recevoir la matière de chargement, et une partie en saillie (40) qui possède l'ouverture de chargement (42) et qui est fixée sur le couvercle (20) ou sur la cuve (10). Le four possède une hauteur de remplissage maximale (H2) et le moyen de retenue pivotant est basculé dans la partie saillante en vue du chargement. La cuve, le couvercle, le dispositif de chargement, le moyen de retenue et la partie saillante possèdent des dimensions telles que la zone de pivotement du moyen de retenue se trouve au-dessus de la hauteur de remplissage maximale (H2). Ledit four est caractérisé en ce que le dispositif de chargement comporte au moins deux paniers (32) à matière autoporteurs qui peuvent être placés au-dessus de la partie saillante (40) et peuvent en être éloignés. Ces paniers possèdent chacun un espace interne qui peut être fermé du côté inférieur du panier (32) par le moyen de retenue (31) et qui contient le volume (C) destiné à recevoir la matière de chargement. Ledit four comporte en outre un dispositif de changement (33) destiné à changer et à mettre en place les paniers (32) à matière.
