The present invention relates to a melting device comprising a loading shaft (13, 13a) and a tilting device (4) by means of which a furnace vessel (1) with a furnace vessel cover (10) can be tilted into different tilt positions around a tilt axis (5a), wherein the furnace vessel sealing region is formed as a convex, cylindrical mantel section shaped, surface, and the shaft sealing region of the loading shaft (13, 13a) is formed as a complementary concave, cylindrical mantel section shaped, sealing surface, such that sections of the sealing surfaces of the two sealing regions lie mutually opposite one another in the different tilt positions of the tilting device (4) such that the transition region between the loading shaft (13, 13a) and the furnace vessel (1) is at least substantially sealed in all tilt positions of the furnace vessel (1), and to a melting method, in which a bunker container (17, 17a) with charging material (39, 40, 41) is placed in front of the loading shaft (13, 13a) on the loading side, wherein over the further course of this method, the charging material (39, 40, 41) is preheated in the bunker container (17) by furnace gas, and after further transport of this charging material (39, 40, 41) from the bunker container (17, 17a) into the loading shaft (13), this charging material (39, 40, 41) is further preheated in the loading shaft (13) by furnace gas.

A melting device having a feed shaft and a tilting device, by means of which a furnace vessel with a furnace vessel cover is tiltable about a tilt axis into different tilt positions, where the furnace vessel cover has a charging opening, to which a flat sealing element is connected on each of two sides, such that the outside boundary of said sealing elements and the outside boundary of the charging opening define a furnace vessel sealing region with a sealing surface which surrounds the charging opening, said furnace vessel sealing region is realized as a convex, cylinder-surface-portion-shaped surface, a further sealing element is also connected on each of two sides of the opening of the feed shaft facing the charging opening in such a manner that the outside boundary of said further sealing elements and the outside boundary of said opening of the feed shaft define a shaft sealing region with a complementary concave, cylinder-surface-portion-shaped sealing surface, portions of the sealing surfaces of the two sealing regions are located opposite one another in each case in the different tilt positions of the tilting device.
A melting method which is carried out by a melting device with a furnace vessel and a feed device, the feed device comprises a feed shaft and a charging material bunker having a bunker container, said method having the following steps:
