Abstract
In a tiltable metallurgical furnace vessel having a completely closed lateral protrusion with a closable discharge opening on its underside, simplified furnace structure is achieved by configuring the protrusion as a removable, heatable fore-hearth that is constructed in the form of a casting spout. A particularly simple structure results due to the fact that the fore-hearth is flanged to the main furnace vessel and essentially has a box shape. The invention is particularly useful for electric arc furnaces.
