- This method of furnace requires the use of highly wear-resistant brick lining or water-cooled wall elements and water-cooled lids.

- the upper and lower parts of the vessel jacket are detachably connected to one another by screw connections (not shown).
- the vertical ribs 7 with which this jacket part is provided all around can be seen on the vessel jacket lower part 3. These ribs 7 serve to enlarge the heat-emitting surface and, in this respect, are intended to avoid heat accumulation in the vessel jacket.

- Stiffening rings 11, which are connected to the furnace supporting structure 4, are placed around the lower part 3 of the vessel shell.
- rib 7 on the right, which is welded to the vessel jacket 3 over the entire surface.

Abstract
Description
Die Erfindung betrifft ein Schmelzgefäß, insbesondere Lichtbogenofen, mit feuerfester Auskleidung oder teilweiser Auskleidung mit wassergekühlten Wandelementen.The invention relates to a melting vessel, in particular an arc furnace, with a refractory lining or partial lining with water-cooled wall elements.
Lichtbogenöfen mit Ausgußschnauze oder Bodenabstich werden heutzutage mit hohen elektrischen Leistungen und kurzen Chargenzeiten gefahren. Diese Ofenfahrweise bedingt den Einsatz von hochverschleißfester Ausmauerung oder wassergekühlten Wandelementen sowie wassergekühlten Deckeln. Die im Schmelzgefäß vorhandene Ausmauerung, insbesondere im Bereich unmittelbar über der Schlackenzone und an den hot spots, ist infolgedessen einer steigenden Belastung ausgesetzt, die einen früheren Verschleiß zur Folge hat und damit zum öfteren Auswechseln der verschlissenen Teile zwingt.Arc furnaces with pouring spouts or floor tapping are nowadays operated with high electrical outputs and short batch times. This method of furnace requires the use of highly wear-resistant brick lining or water-cooled wall elements and water-cooled lids. The lining in the melting pot, especially in the area directly above the slag zone and at the hot spots, is consequently exposed to an increasing load, which results in earlier wear and thus forces the worn parts to be replaced more often.
Um die Haltbarkeit der Ausmauerung in den gefährdeten Bereichen zu verbessern, wurden spezielle Steinqualitäten, wie beispielsweise kohlenstoffhaltige Steine, entwickelt. Mit diesen Steinqualitäten lassen sich infolge des hohen Wärmedurchgangs längere Standzeiten erreichen.To improve the durability of the brickwork in the endangered areas, special stone qualities, such as carbon-containing stones, were developed. With these stone qualities, longer service lives can be achieved due to the high heat transfer.
Der hohe Wärmedurchgang führt nicht nur örtlich, sondern auch großflächig zur Uberhitzung der Mantelbleche. Bei Mantelblechen, deren radiale Dehnung behindert ist, wirkt sich diese hohe Temperaturbelastung in der Weise aus, daß Verformungen der Mantelbleche auftreten, die letztlich zur Zerstörung nicht nur der Mantelbleche selbst, sondern auch des Stützgerüstes des Schmelzgefäßes führen können.The high heat transfer leads not only locally, but also over a large area to the overheating of the jacket sheets. In the case of cladding sheets whose radial expansion is impeded, this high temperature load has the effect that deformations of the cladding sheets occur, which can ultimately lead to the destruction not only of the cladding sheets themselves, but also of the supporting structure of the melting vessel.
Aufgabe der Erfindung ist es, eine Schmelzgefäßkonstruktion zu entwickeln, die den Einsatz der zuvor genannten optimierten Steinqualitäten ermöglicht, ohne daß die aufgezeigten Nachteile entstehen.The object of the invention is to develop a melting vessel construction which enables the use of the aforementioned optimized stone qualities without the disadvantages mentioned.
Diese Aufgabe wird in der Weise gelöst, wie es in den Patentansprüchen angegeben ist.This object is achieved in the manner as specified in the claims.
Durch die Anordnung von vertikalen Rippen, Vorsprüngen oder dergl. im Bereich der feuerfesten Auskleidung des Schmelzgefäßes wird die wärmeabgebende Ofenfläche vergrößert, so daß im Gefäßmantel ein Wärmestau verhindert wird.The arrangement of vertical ribs, projections or the like in the area of the refractory lining of the melting vessel increases the heat-emitting furnace area, so that heat accumulation in the vessel jacket is prevented.
Die vertikale Anordnung der Rippen oder dergl. erweist sich insofern als besonders vorteilhaft, als eine natürliche, gerichtete Luftströmung mit guter Konvektion erzielbar ist und die radiale Wärmedehnung des Gefäßmantels nicht behindert wird.The vertical arrangement of the ribs or the like proves to be particularly advantageous in that a natural, directed air flow with good convection can be achieved and the radial thermal expansion of the vessel jacket is not hindered.
Die Rippen, Vorsprünge oder dergl. lassen sich ganzflächig an den Gefäßmantel anschweißen, worunter eine Schweißverbindung über die gesamte Stirnfläche der Rippen, die am Gefäßmantel anliegen, zu verstehen ist. Andererseits kann es auch zweckmäßig sein, die Rippen oder dergl. mit durchgehenden oder aber unterbrochenen Kehlnähten an den Gefäßmantel anzuschweißen.The ribs, protrusions or the like can be welded to the entire surface of the vessel jacket, which means a welded connection over the entire end face of the ribs which bear against the vessel jacket. On the other hand, it can also be expedient to weld the ribs or the like to the vessel jacket with continuous or interrupted fillet welds.
Als Rippen, Vorsprünge usw. sind eine ganze Reihe von Ausführungsformen denkbar. Man kann Rippen aus Blechstreifen, Profilstählen (z.B. L-, T-, U-Profilen usw.) oder Hohlprofilen herstellen. Als Material zur Herstellung der Rippen läßt sich Stahl, Stahlguß, Grauguß, Nichteisenmetall oder Verbundmetall verwenden.A whole series of embodiments are conceivable as ribs, projections, etc. Ribs can be made from sheet metal strips, section steels (e.g. L, T, U sections etc.) or hollow sections. Steel, cast steel, cast iron, non-ferrous metal or composite metal can be used as the material for producing the ribs.
Der Gefäßmantel mit Rippen oder dergl. läßt sich aber auch so herstellen, daß dieser Mantel aus mehreren Mantelsegmenten besteht, wobei die einzelnen Mantelsegmente T-, U- oder L-Profile sind, die durch vertikales Aneinanderschweißen den Gefäßmantel mit Rippen bilden.The vessel jacket with ribs or the like can also be produced in such a way that this jacket consists of several jacket segments, the individual jacket segments being T, U or L profiles which form the vessel jacket with ribs by vertical welding to one another.
Die am Gefäßmantel angeordneten Rippen, Vorsprünge oder dergl. können, was sich als besonders vorteilhaft herausgestellt hat, so gestaltet werden, daß durch ihre Formgebung vollständig oder teilweise geschlossene vertikale Kühlkanäle gebildet werden.The ribs, protrusions or the like arranged on the vessel jacket can, which has been found to be particularly advantageous, be designed in such a way that vertical or completely closed vertical cooling channels are formed by their shape.
Um die natürliche Luftströmung durch die somit entstandenen Kühlkanäle noch zu verbessern, ist es zweckmäßig, den Ringspalt zwischen der Kippbühne des Ofens und dem Ofengefäßmantel so groß zu bemessen, daß die Breite des Ringspaltes mit den Abmessungen der durch die Rippen am Gefäßmantel gebildeten Kühlkanäle übereinstimmt. Der Luftumsatz zur Verbesserung der Konvektion an der Schmelzgefäßwand läßt sich gegebenenfalls noch weiter verbessern, wenn man eine Fremdbelüftung durch Ventilatoren vorsieht.In order to improve the natural air flow through the cooling channels thus created, it is expedient to dimension the annular gap between the tilting platform of the furnace and the furnace vessel jacket so large that the width of the annular gap matches the dimensions of the cooling channels formed by the ribs on the vessel jacket. The air conversion to improve the convection on the melting vessel wall can possibly be further improved if external ventilation by fans is provided.
