Description
Gegenstand des Hauptpatents ist eino Ofenanlage zur Wärmebehandlung von Werkstücken unter Schutzatmosphäre, wobei an eine einzige Vorkammer zwei oder mehrere Glühofen angeschlossen sind und eine mechanische Fördereinrichtung, mit der das Glühgut nach allen Seiten ein und ausgestoßen werden kann, gasdicht und drehbar in der Vorkammer angeordnet istThe subject of the main patent is a furnace system for the heat treatment of workpieces in a protective atmosphere, two or more annealing furnaces are connected to a single antechamber and one mechanical conveying device with which the annealing material can be fed in and out on all sides, is arranged gas-tight and rotatable in the antechamber
An die Vorkammer sollen hierbei z. B. Kohlungsöfen angeschlossen werden. Derartige Anlagen sind insbesondere für kleinere und mittlere Durchsatzmengen geeignetTo the antechamber here z. B. charcoal furnaces can be connected. Such systems are in particular suitable for small and medium throughput quantities
Gegenstand der Erfindung ist eine Verbesserung der Ofenanlage nach dem Hauptpatent dadurch, daß einer der an die Vorkammer angeschlossenen öfen als Tunnelofen ausgebildet ist, an dessen anderem EndeThe invention is to improve the furnace system according to the main patent in that one the furnace connected to the antechamber is designed as a tunnel furnace, at its other end
eine oder mehrere Kammern mit einer Fördereinrichtung angeschlossen sind, wobei an diese Kammer ein oder mehrere Glühöfen und/oder Entnahmevorrichtungen angeschlossen sind.one or more chambers are connected to a conveyor, with a or several annealing furnaces and / or extraction devices are connected.
Durch eine derartige Ausführung werden die Nachteile der vorhandenen Durchstoßöfen beseitigt Sie ist insbesondere für größere Durchsätze geeignetSuch a design eliminates the disadvantages of the existing pusher ovens is particularly suitable for larger throughputs
In der Abbildung 1 ist eine der möglichen Ausführungen der Erfindung dargestelltIn Figure 1, one of the possible embodiments of the invention is shown
Diese zeigt eine Vorkammer I1 deren Einzelheiten im Hauptpatent dargestellt sind mit einem Beschickungstisch 2 und zwei angeschlossenen öfen 3 und 4, z. B. zum Vorwärmen. In der Kammer 1 erfolgt eine einwandfreie Spülung der Chargen und eine Vorwärmung auf 80 bis 100° C Die Vorwärmung in der Kammer 3 erfolgt dann von 100 auf 6500C unter normalem Trägergas. In der Kammer 4 erfolgt dann eine weitere Vorwärmung von 650 auf 930° C unter Trägergas und langs-umer Einstellung auf den korrekten Kohlungspegel. NachThis shows an antechamber I 1 the details of which are shown in the main patent with a loading table 2 and two connected ovens 3 and 4, z. B. for preheating. In the chamber 1, a proper flushing of the batches and preheating to 80 is carried out to 100 ° C Preheating in the chamber 3 then takes place from 100 to 650 0 C under normal carrier gas. In the chamber 4 there is then a further preheating from 650 to 930 ° C. under carrier gas and slower adjustment to the correct carbonization level. To
-o Einreichen der Gaskohlungstemperatur wird die Charge im Durchlauf in den eigentlichen Kohlungskanal 5 gestoßen. Das Stoßen durch den Tunnelofen 5 erfolgt mit der in der Kammer 1 vorgesehenen Fördereinrichtung. An den Tunnelofen 5 ist beispielsweise eine zweite Kammer 6 angeschlossen, die entsprechend der Kammer 1 ausgebildet ist Durch diese kann ihrerseits eine Härtekammer 7 und eine Härtekammer 8 beschickt werden. Der Kammer 6 kann ein ölbad angeschlossen sein bzw. eine Gaskühlstation. Die Entnahme aus der-o Submitting the gas carbonation temperature will be the batch Bumped into the actual Kohlungskanal 5 in the passage. The pushing through the tunnel furnace 5 takes place with the conveyor device provided in chamber 1. At the tunnel furnace 5 is, for example, a second Chamber 6 connected, which is designed in accordance with the chamber 1 a hardening chamber 7 and a hardening chamber 8 are charged. The chamber 6 can be connected to an oil bath his or a gas cooling station. The removal from the
vorrichtungen 9 bzw. 10 erfolgen, wobei eine Wasch- und Spülstation 11 und eine Anlaßstation 12 mit einemdevices 9 and 10 take place, with a washing and rinsing station 11 and a starting station 12 with a
n Anlaßöfen erweitern. n Expand tempering furnaces.
Die A b b. 2 zeigt ein Flußschema, bei dem an das Ölbad und die Gasabkühlstation 6 nach A b b. 1 seitlich eine weitere drehbare Station 14 angeschlossen ist, die im Gegenlauf zu weiteren Härte- oder V.'?imestationen führtThe A b b. 2 shows a flow diagram in which the oil bath and the gas cooling station 6 according to A b b. 1 on the side a further rotatable station 14 is connected, which runs in the opposite direction to further hardness or V.
