Abstract
Description
Die Erfindung betrifft einen Wärmebehandlungsofen, insbesondere einen Drucksinterofen mit einem Ofengehäuse, einem vom Ofengehäuse gehaltenen und mit Abstand umschließenden, einen Kesselraum bildenden Isolationskäfig, einer im Inneren des Isolationskäfigs angeordnet, die Werkstückcharge umhüllenden mit dem Isolationskäfig einen Isolationsraum begrenzenden Muffel und einer Einrichtung für den Einlaß von Kühlgas aus einem Gasvorratsbehälter in die vom Ofengehäuse, dem Isolationskäfig und der Muffel begrenzten Räume.The invention relates to a heat treatment furnace, in particular a pressure sintering furnace with a furnace housing, a from the furnace housing held and enclosing by a distance, forming a boiler room Isolation cage, one inside the isolation cage arranged, the workpiece batch enveloping with the isolation cage an insulation space delimiting muffle and a device for the inlet of cooling gas a gas storage container into the from the furnace housing, the isolation cage and the muffle limited spaces.
Zur Verkürzung von Kühlprozessen existieren, für verschiedene
Anlagensysteme (z.B. in Muffel-, Durchlauf- oder Durchstoßöfen) unterschiedliche Lösungsansätze. Wesentliche
Merkmale dieser Systeme sind Gaseinleitungen von einer festen Position (
Der vorliegenden Erfindung liegt die Aufgabe zugrunde bei einem Wärmebehandlungsofen des eingangs genannten Typs bei geschlossener Isolation und geschlossener Muffel eine beschleunigte Abkühlung der Charge zu erreichen.The present invention lies based on the task in a heat treatment furnace of the type mentioned at the beginning with closed insulation and closed Muffle an accelerated cooling to achieve the batch.
Darüber hinaus sollen durch eine gezielte Ein- und Umströmung einzelne Ofenbereiche getrennt kühlbar sein. Schließlich soll der Wärmebehandlungsofen so ausgelegt sein, daß im Bedarfsfall auf eine externe Kühleinrichtung mit Wärmetauscher und zusätzlichem Gebläse geschaltet werden kann.In addition, through a targeted inflow and flow around Individual areas of the oven can be cooled separately his. Finally the heat treatment furnace be designed so that in If necessary, an external cooling device with heat exchanger and additional fan can be switched.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein Mehrwegeventil mit einem durch den Isolationskäfig und die Muffel hindurchgeführten Ventilgehäuse mit mindestens drei Gasaustrittsöffnungen vorgesehen ist, wobei an den jeweils einander diametral gegenüberliegenden Stirnwänden des Isolationskäfigs und den Stirnwänden der Muffel vorgesehene am Ofengehäuse angelenkte und gegenüber den Stirnwänden des Ofengehäuses verschließbare Partien des Isolationskäfigs und der Muffel angeordnet sind.According to the invention, this object solved, the existence Multi-way valve with a valve housing passed through the insulation cage and the muffle at least three gas outlets is provided, with diametrically opposite each other end walls of the insulation cage and the end walls the muffle provided articulated on the furnace housing and opposite the end walls lockable parts of the furnace housing of the insulation cage and the muffle are arranged.
Vorzugsweise ist das Mehrwegeventil aus einem fingerförmigen Gehäuse mit mindestens drei Querbohrungen für den Gasaustritt gebildet die in eine mit dem Gasanschluß verbundene, sich in Längsrichtung des Ventilgehäuses erstreckende Sacklochbohrung einmünden, wobei in der Sacklochbohrung ein drehbares und/oder längsverschiebbares mit Querbohrungen versehenes, über eine Ventilstange betätigbares Ventilglied in Gestalt eines Rohrstücks gelagert ist, dessen Querbohrungen je nach seiner Lage in der Sacklochbohrung des Ventilgehäuses mit den Gasaustrittsöffnungen korrespondieren.The multi-way valve is preferably from a finger-shaped casing formed with at least three cross holes for the gas outlet the one connected to the gas connection, itself in the longitudinal direction of the valve housing extend into the blind hole, being in the blind hole a rotatable and / or longitudinally displaceable with cross holes, over a valve rod operable Valve member is mounted in the form of a pipe section, the transverse bores depending on its location in the blind hole of the valve housing with the gas outlet openings correspond.
In einer bevorzugten Ausführungsform ist das Ofengehäuse mit einem Gasauslaß versehen, der über eine Rohrleitung in die ein Wärmetauscher und ein Gebläse eingeschaltet sind mit dem Gasanschluß über ein Ventil verbindbar.In a preferred embodiment is the furnace housing provided with a gas outlet that over a Pipeline in which a heat exchanger and a blower switched on can be connected to the gas connection via a valve.
Mit Vorteil ist durch den Gasauslaß am Ofengehäuse eine Ventilstange hindurchgeführt deren durch den Kesselraum bis in den Isolationsraum hineinragendes Ende mit einem Stopfen fest verbunden ist mit dem ein Gasdurchlaß in der festen Wand des Isolationskäfigs verschließbar ist.One advantage is through the gas outlet on the furnace housing Valve rod passed through their protruding through the boiler room into the isolation room End is firmly connected to a plug with a gas passage in the solid wall of the insulation cage lockable is.
Die Stirnwände des Isolationskäfigs oder der Muffel oder Partien dieser Stirnwände sind erfindungsgemäß mit hydraulisch, elektrisch oder mechanisch betätigbaren an den Stirnwänden des Ofengehäuses gelagerten oder abgestützten Zugankern oder Verschiebegliedern verbunden mittels derer sie gegenüber dem ortsfesten Ofengehäuse soweit verschiebbar sind, daß sich Spalte bilden über die Kühlgas vom Chargenraum über den Isolationsraum in den Kesselraum und von diesem über den Gasauslaß in die Rohrleitung rückströmen kann.The end walls of the insulation cage or the muffle or parts of these end walls are hydraulic according to the invention, operated electrically or mechanically on the end walls of the furnace housing stored or supported Tie rods or sliding links connected by means of which they face the stationary furnace housing are movable so far that Form column over the cooling gas from the batch room above the isolation room in the boiler room and from this over the Gas outlet in the pipeline can flow back.
