Description
Regenerativherdofen mit bis an den Herd herangeführten Regeneratoren. Der Siemens-Mardn-Regenerativofen wird in erster Linie zum Schmelzen und zur Hzrstellung von S#Ziemens--lartin-Stahl. weniger dagegen zum Raffinieren von Stahl benutzt, da die zum Raffinieren notwendige hohe Temperatur bei den gebräuchlichen Regenerativkaminern nur schwer zu erreichen ist.Regenerative hearth furnace with regenerators brought up to the hearth. The Siemens-Mardn regenerative furnace is primarily used for smelting and production by S # Ziemens - lartin steel. used less for refining steel, because of the high temperature required for refining with conventional regenerative stoves difficult to achieve.
Es sind zwar schon Herdöfen bekannt geworden, bei denen die Regenerativkammern zwecks Erhöhung der Temperatur bis an den Herd herangeführt sind. doch bewirkte hier die mitgerissene rlüssige Schlacke einen schnellen Verschl.eih der an den Ofenköpfen liegenden Kammersteine.Hearth furnaces with regenerative chambers have already become known are brought up to the stove to increase the temperature. but caused here the entrained liquid slag quickly deteriorates on the furnace heads lying chamber stones.
Aus diesen Gründen wird das Raffinieren von Stahl besonders bei den besseren Stahlsorten zumeist im Elektroofen vorgenommen. welcher jedoch infolge der hohen Stromkosten recht unwirtschaftlich arbeitet.For these reasons, steel refining is particularly popular with the Better types of steel are mostly made in an electric furnace. which however as a result works quite uneconomically due to the high electricity costs.
Die Erfindung betrifft nun einen Regenerativofen, dessen Regenerativkammern zwecks Erreichung hoher Arbeitstemperaturen bis an den Herd herangeführt sind. Erfindungsgemäß sind dabei die Köpfe der Regeneratoren gegen den Herd hin geneigt, damit die im Gitterwerk sich bildende Schlacke in den Herd zurückfließt. Hierdurch ist es möglich. den Siemens-Martin-Ofen in weitgehendem 'Maße auch zum Raffinieren von Stahl zu verwenden, wodurch infolge geringerer Anlagekosten und praktisch restloser Rückgewinnung der in den Abgasen enthaltenen Wärme erhebliche Ersparnisse erzielt werden. Eine beispielsweise Ausführungsform des Erfindungsgegenstandes zeigt die Zeichnung, und zwar ist Abb. i ein senkrechter und Abb. a ein wagerechter Schnitt durch den Ofen.The invention now relates to a regenerative furnace, its regenerative chambers are brought up to the stove in order to achieve high working temperatures. According to the invention the heads of the regenerators are inclined towards the stove so that the im Lattice-forming slag flows back into the hearth. This makes it possible. largely used the Siemens-Martin furnace for refining steel use, which results in lower investment costs and practically complete recovery the heat contained in the exhaust gases considerable savings can be achieved. One example embodiment of the subject matter of the invention shows the drawing, and although Fig. i is a vertical and Fig. a is a horizontal section through the furnace.
Zu beiden Seiten des Ofens liegen die Re-enerativkammcrn b, welche bei a bis an den Herd herangeführt sind. Die Kammerköpfe weisen gegen den Herd eine Neigung auf, damit die im Gitterwerk sich bildende Schlacke in den Herd zurückfließt. Zur praktisch restlosen Übertragung der Abgaswärme auf das vorzuwärmende Mittel sind die Kammern b durch die Kammern c und d verlängert. Die Verbrennungsluft wird bei e in bekannter "Geleise abwechselnd der einen oder der anderen Kammer zugeführt. Zweckmäßig ist es, den Brennstoff dicht vor den durch die Kammersteine gebildeten Ofenköpfen durch das Herdgewölbe mit Hilfe von Brennern f derart einzuführen, daß der auf das Bad gerichtete Brennstoffstrom den Luftstrom in einem Winkel von etwa go° schneidet.On both sides of the furnace are the re-energizing chambers b, which are brought up to the hearth at a. The chamber heads are inclined towards the hearth so that the slag that forms in the latticework flows back into the hearth. For practically complete transfer of the exhaust gas heat to the means to be preheated, chambers b are lengthened by chambers c and d. The combustion air is alternately supplied to one or the other chamber at e in known "tracks. It is expedient to introduce the fuel through the hearth vault with the aid of burners f close to the furnace heads formed by the chamber stones so that the fuel flow directed onto the bath cuts the airflow at an angle of about go °.
