Description
Ausgleichherd für Stoß- oder Durchstoßöfen zur Wärmebehandlung von metallischem Gut Es ist bekannt, bei Stoß- oder Durchstoßöfen zur Wärmebehandlung von metallischem Gut in Brammen-, Knüppel-, Platten- oder ähnlicher Form, vorzugsweise am Ausstoßende, einen vollflächigen Ausgleichherd vorzusehen, der sich an einen voraufgegangenen Schienenherdteil anschließt und dem die Aufgabe zufällt, als kurzzeitige Lagerstätte und auch als Gleitbahn für das Wärmgut zu dienen. In diesem Bereich des Ofens soll ein Temperaturausgleich über den gesamten Gutquerschnitt erfolgen. Um das Wärmgut auf dem Ausgleichherd zu wenden, hat man bereits vorgeschlagen, den Herd mit ein oder zwei denselben quer zur Gutförderrichtung durchziehenden Nuten zu versehen, welch letztere als Kippkanten dienen.Compensating hearth for push or pusher furnaces for heat treatment of Metallic goods It is known in push or pusher furnaces for heat treatment of metallic material in slab, billet, plate or similar form, preferably at the end of the discharge, to provide a full-area compensating center, which is connected to a previous rail hearth part connects and which the task falls to, as a short-term To serve as a depository and also as a slideway for the heat material. In this area of the furnace, temperature should be equalized over the entire cross-section of the product. In order to turn the heat on the equalizing stove, it has already been proposed to use the Hearth with one or two of the same grooves running across the material conveying direction to provide, which latter serve as tilting edges.
Bei Industrieöfen mit vollflächigem Ausgleichherd mußte bisher der Ofen von Zeit zu Zeit stillgesetzt werden, damit der sich auf der Ausgleichherdfläche absetzende Zunder entfernt werden konnte. Diese Arbeiten wurden meist über das Wochenende ausgeführt, so daß eine durchgehende Arbeitsweise unmöglich war. Da der laufend anfallende Zunder aber nur in zeitlichen Abständen beseitigt werden konnte, ließ es sich nicht vermeiden, daß er teilweise auf der Herdfläche festbackte, zumal der Zunder durch das zu wärmende Gut auf die Herdfläche aufgepreßt wurde.In industrial furnaces with a full-area equalizing hearth, the The furnace must be shut down from time to time so that it is on the equalizing hearth surface settling scale could be removed. This work was mostly done over the weekend executed, so that a continuous operation was impossible. Since the ongoing however, it was only possible to remove the scale at intervals it cannot be avoided that it partially baked on the stove surface, especially the Tinder was pressed onto the stove surface by the material to be heated.
Da dieses Anwachsen erfahrungsgemäß unregelmäßig erfolgte, wurde die als Gleitfläche dienende Herdoberfläche sehr bald so stark uneben, daß deren Erneuerung erforderlich war.Since experience has shown that this growth was irregular, the The hearth surface serving as a sliding surface very soon became so uneven that it was renewed was required.
Zur Vermeidung des aufgezeigten Nachteils wird erfindungsgemäß vorgeschlagen, den Ausgleichherd über seine gesamte Länge mit mit geringem Abstand zueinander angeordneten, im Grundriß etwa keilförmig ausgebildeten, mit der Keilschneide entgegen der Gutförderrichtung verlaufenden rinnenförmigen, an sich bekannten Ausnehmungen zu versehen, die von Herdbreitseite zu Herdbreitseite durchgehen. Als besonders zweckmäßig wird der Vorschlag angesehen, die beiden von den Herdbreitseitenenden ausgehenden Schenkel jeder keilförmig verlaufenden Rinne so anzuordnen, daß sie miteinander einen Winkel von etwa 90° einschließen. Wie die Erfindung weiter vorsieht, soll zweckmäßig die Rinnenspitze einer keilförmigen Rinne - in Durchlaufrichtung des Wärmgutes gesehen - in Höhe des Rinnenschenkelanfanges der voraufgegangenen Rinne liegen. Im Rahmen der Erfindung liegend wird auch der Vorschlag angesehen, jedem Rinnenende eine an sich bekannte Putzöffnung zuzuordnen. Schließlich ist in zweckmäßiger Weiterbildung des Erfmdungsvorschlages die Verwendung von Steinen für die Herdzustellung möglich, die aus einem oberhalb 1750° C erweichenden gegossenen Schmelzfluß aus Metalloxyden bestehen.To avoid the disadvantage shown, it is proposed according to the invention that the equalizing center over its entire length with a small distance from each other, approximately wedge-shaped in plan, with the wedge edge against the direction of material conveyance extending channel-shaped, known recesses to be provided by Go through the broad side of the stove to the broad side of the stove. The suggestion is found to be particularly useful viewed, the two legs emanating from the hearth broadside ends are each wedge-shaped to arrange the running channel so that they form an angle of about 90 ° with each other lock in. As the invention further provides, the gutter tip should expediently a wedge-shaped channel - seen in the direction of flow of the heated goods - in height of the beginning of the channel leg of the previous channel. Within the scope of the invention The suggestion that each end of the channel be known per se is also considered horizontally Allocate cleaning opening. Finally, in an expedient development of the proposed invention the use of stones for the stove can be made from an above 1750 ° C softening poured melt flow consist of metal oxides.
Durch die Anwendung der Erfindungsvorschläge ist es möglich, die Ausgleichherdfläche frei von Zunder zu halten, einen kontinuierlich betriebenen Ofenbetrieb zu gewährleisten und die Lebensdauer der Herdausmauerung erheblich zu verlängern.By applying the inventive proposals, it is possible to reduce the area of the compensating center to keep them free of scale, to ensure that the furnace operates continuously and to significantly extend the service life of the hearth lining.
An Hand der Zeichnung, die perspektivisch einen Ausschnitt aus einem erfindungsgemäß ausgebildeten Ausgleichherdofenteil darstellt, sei die Erfindung beispielhaft erläutert.On the basis of the drawing, the perspective view of a section of a represents according to the invention designed equalizing hearth furnace part, let the invention explained by way of example.
Der Herdteil 1 der gezeigten Ausführungsform der Erfindung besteht aus einem Mauerwerk aus Steinen 2 und 3, die vorzugsweise aus einem oberhalb 1750° C erweichenden, gegossenen Schmelzfluß aus Metalloxyden bestehen. Im wesentlichen sind alle Steine 2 und alle Steine 3 unter sich gleich, zueinander jedoch unterschiedlich groß, vor allem unterschiedlich hoch, so daß je nach Anordnung der Steine Nuten 10,11 entstehen, welche die Herdfläche unterbrechen. Werden die Rinnenausnehmungen so angeordnet, daß die Nuten 10 von der einen Seitenkante aus nur bis zur Breitenmitte führen und dort in die von der anderen Längsseite des Herdes ausgehenden Nuten 11 einmünden, so daß jede die gesamte Herdbreite durchsetzende Nut einen Winkel von etwa 90° bildet, so ergibt dies die zweckmäßigste Ausführungsform des Erfindungsvorschlages.The stove part 1 of the embodiment of the invention shown consists from a masonry made of stones 2 and 3, preferably from one above 1750 ° C softening, poured melt flow consist of metal oxides. Essentially all stones 2 and all stones 3 are the same among themselves, but different from one another large, especially different heights, so that grooves depending on the arrangement of the stones 10,11 arise, which interrupt the hearth surface. Will the gutter recesses arranged so that the grooves 10 from one side edge only up to the center of the width and there into the grooves 11 extending from the other longitudinal side of the cooker open out, so that each groove penetrating the entire hearth width forms an angle of forms about 90 °, this results in the most expedient embodiment of the inventive proposal.
Der Unterschied in der Höhe der Steine 2 und 3 hängt in erster Linie von den Betriebsbedingungen des betreffenden Ofens ab; im allgemeinen sollen die Steine 3 etwa die halbe Höhe der Steine 2 aufweisen.The difference in the height of stones 2 and 3 depends primarily on the operating conditions of the furnace in question; in general, the Bricks 3 have about half the height of bricks 2.
Durch die seitlichen Putzöffnungen 4 kann der in den rinnenförmigen Ausnehmungen liegende Zunder während des Ofenbetriebes mittels Schabern ausgeräumt werden.Through the lateral cleaning openings 4, the can in the channel-shaped Scale lying in recesses during the furnace operation by means of scrapers be cleared out.
