Durchlaufofen mit HubbalkenContinuous furnace with walking beam
Die Erfindung betrifft einen Durchlaufofen mit imbbalken,,The invention relates to a continuous furnace with imbbalken ,,
Die Aufgabe der Erfindung liegt darin, einen Durchlaufofen mit Hubbalken zu schaffen, bei dem die Förderung der Charge in einem beliebigen ieil des Durchlaufofens unterbrochen werden kann, ohne daß die Forderbewegung der Hub-'balken abgestoopt werden muße The object of the invention is to create a continuous furnace with walking beams, in which the conveyance of the batch can be interrupted in any part of the continuous furnace without the conveying movement of the lifting beams having to be stopped e
Diese Aufgabe wird erfindungagemäß dadurch gelöst, daß eier zwischen zwei Hubbalken befindliche Herdteil wenigstens ■juf einem Abschnitt der Länge des Durchlauf of ens auf ein liiveau oberhalb des IJiveaus anhebbar ist, das die Hubbalken während ihrer Förderbewegung erreichen»This object is achieved according to the invention in that Eggs located between two walking beams hearth part at least ■ on a section of the length of the continuous furnace li level can be raised above the level that the lifting beam achieve during their conveying movement »

zone 4, in der die Antriebe 5 und 6 für die Hubbalken 7 und 8 angeordnet sind0 Die Hubbalken 7 und 8 können in der üblichen · Vveise eine hin- und hergehende Bewegung ausführen, wobei sie während ihrer Vorwärtsbewegung angehoben werden, so daß die Charge 9 aus der Herdebene herausgehoben wird, .bei dem dargestellten Ausführungsbeispiel weist der Herd vier in Längsrichtung verlaufende Tragrippen 10, 11, 12 und 13 auf, von denen die Tragrippen 10 und 11 auf je einer Jeite des Hubbalkens 8 und die Tragrippen 12 und 13 auf je einer Gelte des Hubbalkens 7 liegen, νIe Hubbalken 7 und 8 bew-.gen sich vorwärts und rückwärts sowie aufwärts und abwärts, wobei zwischen den üeitenwänden der 'Tragrippen 10, 11, 12, 13 und den Aussenseiten der ü bbalken 7 und Üpiel vorhanden ist. Die Antriebe 5 und 6 für die Hubbalken 7 und 8 sind in üblicher weise ausgebildet und brauchen daher im einzelnen nicht beschrieben zu werden.zone 4, in which the drives are positioned 5 and 6 for the lifting beams 7 and 8 0 The lifting beams 7 and 8 can perform a reciprocating movement in the usual · Vveise, where they are raised during their forward movement, so that the charge 9 is lifted out of the hearth plane,. In the embodiment shown, the hearth has four longitudinally extending support ribs 10, 11, 12 and 13, of which the support ribs 10 and 11 each on one side of the lifting beam 8 and the support ribs 12 and 13 Each of the lifting beams 7 is valid, lifting beams 7 and 8 move forwards and backwards as well as up and down, with between the side walls of the support ribs 10, 11, 12, 13 and the outer sides of the beams 7 and playing is. The drives 5 and 6 for the lifting beams 7 and 8 are designed in the usual way and therefore do not need to be described in detail.
Die zwei mittleren, zwischen den Hubbalken 7 und 8 liegenden Tragrippen 11 und 12 sind erfindungsgeinäß bis zu einem bestimmten Niveau oberhalb ihrer normalen Lage anhebbar. Das Jiveau, auf das diese Tragrippen 11 und 12 anzuJH-oen sind, liegt oberhalb des Niveaus, das die Hubbalken 7 und 8 während ihrer Förderbewegung erreich« ^. Wenn also die 'Tragrippen 11 und 12 auf das höchste Niveau angehoben sind, haben sie die von ihnen getragenen Charge 9 so hoch angehoben, so daß die Hubbalken 7>8 die Charge nicht mehr erreichen und aufnehmen können. Die Charge 9 bleibt daher auf den 'Tragrippen 11 und 12 liegen und wird nicht mehr durch den Ofen gefördert. Die Tragrippen 11 und 12 bzw. der Herdteil zwischen den Hubbalken 7 und 8 iat je nach der gewünschten Betriebsweise so ausgebildet, daß er auf der ganzen Länge des Durchlaufofens oder nur auf einen Abschnitt der Länge anhebbar ist.The two middle support ribs 11 and 12 lying between the lifting beams 7 and 8 are according to the invention up to a certain one Level can be raised above its normal position. The Jiveau, on that these support ribs 11 and 12 are to be opened is above the Levels that the walking beams 7 and 8 during their conveying movement reach «^. So if the 'support ribs 11 and 12 on the highest Are raised level, they have lifted the batch 9 they are carrying so high that the walking beams 7> 8 the batch can no longer reach and absorb. The batch 9 therefore remains on the 'support ribs 11 and 12 and is no longer conveyed through the furnace. The support ribs 11 and 12 or the stove part between the walking beams 7 and 8 iat depending on the desired Mode of operation designed so that it can be raised over the entire length of the continuous furnace or only over a portion of the length is.
Der zwischen den Hubbalken 7 und 8 liegende Herdteil ist durch einen Antrieb 14 anhebbar» Dieser Antrieb Tcann Druckzylinder, Balken oder Räder enthalten, auf denen der Herdteil ruht.The stove part lying between the walking beams 7 and 8 is can be raised by a drive 14 »This drive Tcann printing cylinder, Contain bars or wheels on which the stove part rests.
Die Betätigung des anhebbaren und absenkbaren He^teIls wirdThe operation of the liftable and lowerable part is
209823/0827209823/0827
vorzugsweise so gesteuert, daß der Herdteil während der .uufwärtsbewegung der iiubbalken 7,8 oder unmittelbar davor angehoben wird, während er abgesenkt wird, sobald die Hubbalken 7,8 nach unten gegangen sind. Infolge der Tatsache, daß der -"-erdteil, d.h. die irsgrippen 11 und 12, nicht angehoben wird, bevor das Anheben der iiubbalken 7,8 stattgefunden hat, legt sich die Charge 9 normalerweise während der Stillstandszeit in einer bestimmten stellung auf den ganzen Herd und wird damit in gerader Ausrichtung gehalten. V/ürde die Charge 9 nur auf den angehobenen Tragrippen 11 und 12 ruhen, bestände die Gefahr, daß die Enden der Charge gebogen werden.preferably controlled in such a way that the hearth part during the upward movement of the overhead beams 7, 8 or immediately in front of it is raised while it is lowered as soon as the walking beams 7,8 have gone down. As a result of the fact that the - "- continent, i.e. the irs flu 11 and 12, is not raised before the lifting of the overhead beam 7,8 has taken place, the Charge 9 normally in a certain position on the whole stove during the downtime and thus becomes straighter Alignment held. V / would charge 9 only on the raised one Support ribs 11 and 12 rest, there is a risk that the ends of the batch will be bent.
^u bemerken ist in diesem Zusammenhang, daß der anhebbare und absenkbare Herdteil keinen Iiubbalken darstellt, sondern nur eine Aufwärts- und Abwärtsbewegung ausführt, ohne dass die Charge im Durchlaufofen vorwärts bewegt wird, tfenn der anhebbare Herdteil auf das gleiche Niveau wie die anderen Tragrippen und 13 abgesenkt worden ist, ruht die Charge in der üblichen Weise auf dem ganzen Herd und kann von den Hubbalken 7 und 8 erfasst werden, um sie im Durchlaufofen vorzubewegen.^ u notice in this context that the liftable and lowerable hearth part does not represent a lifting beam, but only performs an upward and downward movement without the Batch is moved forward in the conveyor oven, tfenn the liftable Hearth part has been lowered to the same level as the other support ribs and 13, the batch rests in the usual Way on the whole stove and can be from the lifting beams 7 and 8 be detected in order to move them forward in the conveyor oven.
-Entsprechend der gewünschten Stillstandszeit an einer bestimmten Stelle oder in bestimmter Lage im Durchlaufofen kann man den anhebbaren und absenkbaren Herdteil eine bestimmte Anzahl von Knheb- und Absenkbewegungen ausführen lassen, so daß λ die Hubbalken bei ihrer Förderbewegung nur diejenigen Chargen betätigen, die sich vor oder hinter dem anhebbaren und absenkbaren ^erdteil befinden.-According to the desired downtime at a certain point or in a certain position in the continuous furnace, the hearth part which can be raised and lowered can be carried out a certain number of knuckling and lowering movements, so that λ the walking beams only operate those batches in their conveying movement that are in front of or behind the raised and lowerable ^ ground section.
selbstverständlich ist es möglich, den Herd als solchen über die ganze iJ-erdlänge anhebbar und absenkbar auszubilden, jedoch ist dies im allgemeinen nicht erforderlich, weil es insbesondere erwünscht ist, daß der -herd in der Vorwärmzone zwischen den Hubbalken angehoben werden kann und die Chargen hier eine längere Stillstandszeit erhalten«Of course, it is possible to raise and lower the stove as such over the entire length of the earth, but this is generally not necessary because it is particularly desirable that the stove can be raised in the preheating zone between the walking beams and the batches get a longer downtime here «
