Abstract
In order to design the accommodation space of the furnace vessel of a melting furnace to be variable, so that it is adaptable to various volumes, which are required for different feedstocks (light scrap, heavy scrap) to achieve the tapping weight intended for the melting furnace, the cylindrical upper vessel part (102) comprises a first lower (105) and a second upper (106) cylindrical segment, of which one overlaps the other and is constructed to be telescopically displaceable relative to the other by at least one lifting device (21/1, 21/2).
