Description
Es ist bei Flammöfen mit Vorwärm-, Glüh- und Kühlzonen bekannt, die Heiz- und Verbrennung'gase sowohl in der Längs- als auch in der Querrichtung hindurchzuleiten.In flame furnaces with preheating, annealing and cooling zones known, the heating and combustion gases in both the longitudinal and pass in the transverse direction.
Die Erfindung behandelt einen kontinuierlich arbeitenden Flammofen, bei dem sich gegenüberliegende Feuerungen an der Glühzone befinden und Kammern zum Tempern eiligen Gutes umschließen. Die einzelnen Glüh-, Vorwärm- und Kühlzonen sowie die Kammern für eiliges Tetnpergut sind durch Absperrorgane gegeneinander abschließbar.The invention deals with a continuously operating flame furnace with opposing furnaces at the annealing zone and enclose chambers for tempering urgent goods. The individual annealing, preheating and cooling zones as well as the chambers for urgent food items can be locked against each other by shut-off devices.
In der Zeichnung ist ein Ausführungsbeispiel eines solchen kontinuierlich arbeitenden In the drawing is an embodiment of such a continuously operating
Flammofens wiedergegeben. : Flame furnace reproduced. :
Fig. ι zeigt einen Vertikallängenschnitt durch den Flammofen,Fig. Ι shows a vertical length section through the flame furnace,
Fig. 2 einen Horizontalschnitt von Fig. 1, undFig. 2 is a horizontal section of Fig. 1, and
Fig. 3 einen Vertikalschnitt von Fig. 1.FIG. 3 shows a vertical section of FIG. 1.
Das in bekannter Weise in zylindrischen Gefäßen α untergebrachte Tempergut wird auf Rollwagen b in den Schacht c des Ofens gebracht. Durch Schieber d, e, f kann der The tempering material accommodated in a known manner in cylindrical vessels α is brought into the shaft c of the furnace on trolleys b. With slider d, e, f the
»5 Schacht in voneinander getrennte Räume ■ A, B, C und D abgeteilt werden.»5 shafts can be divided into separate rooms ■ A, B, C and D.
Der Raum B, der durch die Schieber d, e seitlich abzuschließen ist, wird durch sich gegenüberliegende Feuerungen g, die auf der The space B, which is to be closed off laterally by the slider d, e, is provided by opposing furnaces g, which are located on the
je Vorder- und Rückseite des Schachtes liegen, geheizt. Zwischen den Heizvorrichtungen g sind besondere Temperräume m vorgesehen, in denen eiliges Tempergui behandelt wird.each front and back of the shaft are heated. Between the heating devices g special tempering spaces m are provided in which urgent tempering material is treated.
Aus dem Räume B, der den eigentlichen · Temperraum bildet, gelangen die Abgase bei offenen Schiebern für die Kammern m in diese, außerdem aber durch beliebig gestaltete Kanäle h in den Raum C, der durch Schieber e, f seitlich abschließbar gemacht ist.From the room B, which forms the actual tempering room, the exhaust gases get into the chambers m when the slides are open, but also through channels h of any shape into the room C, which is made laterally lockable by slides e, f.
Der Raum C bildet den mit den heißesten Abgasen gespeisten Vorwärmeraum.Room C forms the preheating room fed with the hottest exhaust gases.
Aus dem Räume C werden die Abgase, die inzwischen an Temperatur abgenommen haben, durch Kanäle i in den Raum D geführt, der durch Schieber f und zweckmäßig auch durch eine Verschlußtür k abschließbar ist. In diesem Räume D erfolgt nach dem gezeichneten Ausführungsbeispiele die erste Vorwärmung des Tempergutes.From the room C the exhaust gases, which have meanwhile decreased in temperature, are led through ducts i into the room D , which can be locked by slide f and expediently also by a locking door k . The first preheating of the material to be tempered takes place in this room D according to the illustrated exemplary embodiment.
An Stelle zweier Vorwärmekammern C und D 5* können deren nach Bedarf auch mehrere, soweit es die Raumverhältnisse gestatten, angelegt werden.Instead of two preheating chambers C and D 5 *, several can also be created if the space permits.
Der Raum A, der durch Schieber d und zweckmäßig auch durch eine Außentür / abgeschlossen werden kann, dient zum Abkühlen des aus dem Räume B in den Raum α hineingefahrenen Tempergutes.The room A, which can be closed off by slide d and expediently also by an outer door /, is used to cool down the tempering material that has moved from room B into room α.
Eine Zuführung von irgendwelchen Abgasen in den Raum A ist, wie die praktischen βο Erfahrungen gelehrt haben, nicht erforderlich. It is not necessary to feed any exhaust gases into space A , as practical experience has shown.
Der Abzug der Heiz- bzw. Verbrennungsgase erfolgt durch Kanäle n. The heating or combustion gases are extracted through ducts n.
Durch den Gegenstand der Erfindung wer- *5 den tote Räume vollständig vermieden.The subject of the invention completely avoids dead spaces.
