Abstract
In a furnace charge preheater, especially one for scrap metal, in the form of a bucket whose bottom contains at least two outswinging half-shells, the bucket bottom when in the closed state is formed of a central part and at least one ring while the inner margin of the ring overlaps the margin of the central part and the margin of the central part is situated at a distance below the inner margin of the ring thus forming an annular gap. In this manner a more uniform flow of the hot gas through the preheater is assured. Furthermore, if the annular gap between the bucket bottom and the bucket wall is sealed up, the chamber on which the charge preheater is placed when the charge is preheated, can be made smaller.
