Embodiment Construction

[0035] figure 1 A cross-sectional view of the furnace 10 is shown. This furnace 10 has a lid 1 and a crucible 11 . The furnace 10 is shown in the closed state, ie the lid 1 and the crucible 11 form a closed volume. The molten melt S is located in this crucible 11 . This molten material S constitutes molten steel. The slag S' is located above the liquid steel. Furthermore, metal droplets (Metaltropfen) escaping from the steel pool are shown. They at least partly hit the inner surface 13 or 3 of the crucible 11 or lid 1 . if figure 1 The furnace 10 in is constituted like the prior art, then the metal drop that bumps into the inner surface 13 or 3 of the crucible 11 or the lid 1 will be welded together with the inner surface 3 of the crucible 11 or the lid 1 on the respective positions, which A metallic bond that is difficult to break off may develop, which increases in weight and volume over time. If the sticky matter exceeds a certain size or a certain limit size or a c...

Abstract

The invention relates to a cover (1) for a furnace (10) for receiving molten material (S), particularly metal. According to the invention, the cover comprises at least one layer (4, 4'') formed of a material having a heat transfer coefficient greater than that of steel, so that a furnace cover can be provided in which baked-on residue of molten particles discharged from a melt can be reduced or even entirely prevented on the inner surface (3) of the cover. The invention further relates to a furnace (10) for receiving molten material (S), particularly metal, having a crucible (11) that can be filled with molten material (S) and having a cover (1) for closing the crucible (11). Because the cover (1) and / or crucible (11) comprise a layer (4, 4'') made of a material having a heat transfer coefficient greater than that of steel, undesired baked-on residue of molten material particles can be reduced or prevented on the cover surface (3) and / or crucible surface (13).

Description

technical field [0001] The invention relates to a cover for a furnace containing a melt, especially a metal, and to a furnace for containing a melt, especially a metal, having a crucible capable of filling the melt and a cover for closing the crucible. Background technique [0002] During production or preparation, especially during subsequent processing of steel, it is often necessary to convert the steel into a liquid state by heating. High temperatures are usually associated with metals due to their high melting points. Therefore, crucibles and possibly lids adapted to this temperature regime have been developed. [0003] This cover can usually be removed from the crucible and is used during steel melting to retain and selectively vent gases generated during the melting process and to efficiently utilize the introduced melting energy. The cover prevents a large portion of the introduced energy from evaporating upwards unused. [0004] Such lids and crucibles are common...
