Tm PTauptpatent 637 911 ist ein elektrisch beheizter Schwingbalkenofgn zum Glühen von breiten (intern, insbesondere Blechen, in fortlaufendem Arbeitsgang beschrieben, wobei der ()fenherd in eine Anzahl von in geschlossener Hahn bewegten Längszonen unterteilt ist. Bei diesem Durchgangsofen besteht erfindungsgemäß jede Längszonc des Herdes aus einzelnen, im wesentlichen keramischen Tragkörpern, welche in ihrem oberen, dem Glühgut benachbarten Hohlraum elektrische Heizelemente enthalten und nach unten zu wärmeisolierend ausgebildet sind. Diese keramischen Tragkörper ruhen auf eisernen BaI-ken, welche sich über die Längsrichtung des < )fcns gleichlaufend nebeneinander erstrecken und wenigstens zum Teil die erforderlichen Kurvenbewegungen ausführen. Die keramischen Tragkörper auf jedem Schwingbalken bilden somit eine sich über die gesamte Ofenlänge erstreckende ununterbrochene Reihe. Ebenso setzen sich die Heizelemente durch die gesamte Ofenlänge fort. Bei dieser Art des Einbaus der elektrischen Heizung kann (lic Heizleistung in der Länge des Ofens z. B.TM P main patent 637 911 is an electric heated vibrating beam oven for annealing wide (internal, especially sheet metal, in continuous Operation described, with the () open hearth in a number of in closed Hahn is divided into moving longitudinal zones. According to the invention, there is a continuous furnace each longitudinal zone of the hearth is made up of essentially ceramic support bodies, which in their upper, the annealing material adjacent cavity contain electrical heating elements and down to be thermally insulating are trained. These ceramic supporting bodies rest on iron bars, which extend parallel to each other over the longitudinal direction of the fcns and at least partially carry out the required curve movements. The ceramic Carrying bodies on each vibrating beam thus form one over the entire length of the furnace extending continuous series. The heating elements also prevail the entire length of the furnace. With this type of installation the electric heater can (lic heating power in the length of the furnace e.g.
. dadurch geregelt werden, daß die Reihen der Heizelemente, nach einer bestimmten Ileizkurve abgestuft oder zur Erzielung einer beliebigen gewünschten Heizkurve regelbar sind,. be regulated by the fact that the ranks of Heating elements, according to a certain Ileiz curve graduated or adjustable to achieve any desired heating curve are,
Die Erfindung betrifft nun einen elektrisch beheizten Durchgangsofen gemäß dem Hauptpatent, bei dem die Regelung der Heizleistung in der Lange des Ofens in besonders einfacher und zuverlässiger Weise dadurch erzielt wird, daß der von dem durchgehenden eisernen Schwingbalken getragene keramische Teil des Schwingbalkens auf der ganzen Ofenlänge in einzelne Abschnitte unterteilt ist, die je mit einer besonderen regelbaren elektrischen Heizung ausgerüstet sind.The invention now relates to an electrically heated tunnel oven according to the main patent, in which the regulation of the heating power in the length of the furnace in a particularly simple way and is reliably achieved in that that of the continuous iron vibrating beam carried ceramic part of the vibrating beam all over Oven length is divided into individual sections, each with a special adjustable electric heating.
Bei einem Ofen mit z. B. 20 m langer Brennkammer werden also die einzelnen keramischen Schrittmacherbalken, die auf dem durchgehenden metallischen Schwingbalken angeordnet sind, beispielsweise -je 4 m laug, so daß in der Brennkammer fünf getrennt voneinander regelbare Heizkörpergruppen eingebaut werden können. Der durchgehende metallische Schwingbalken ruht auf senkrechten, rohrförmigen Mi'tallsäiilen, die zur Stromzti- und -ableitung für die auf den einzelnen Abschnitten angeordneten elektrischen Heizkörper dienen.In a furnace with z. B. 20 m long combustion chamber are so the individual ceramic pacemaker bars, which are arranged on the continuous metal vibrating beam, for example, each 4 m long, so that five separately controllable radiator groups can be installed in the combustion chamber. The continuous metal vibrating beam rests on vertical, tubular metal columns, which are used to conduct electricity and dissipate the electrical heating elements arranged on the individual sections.
Die Zeichnung zeigt als Ausführungsbeispiel einen elektrischen Durchgangsofen nach der Frfmdung, und zwar Abb. t einen teilweisen Querschnitt und Abb. 2 einen teilweisen Längsschnitt durch den Ofen.As an exemplary embodiment, the drawing shows an electric tunnel oven the formation, namely Fig. t a partial cross-section and Fig. 2 a partial Longitudinal section through the furnace.
Die eisernen durchgehenden Schwingbalken 4 sind wie im Iiauptpiitcnt mit hohlen keramischen Tragkörpern 5 für die elektrische Heizung 13 versehen. Diese keramischen Tragkörper 5 von beschränkter Länge werden nun mit ihrem schwalbenschwanzartigen Fuß auf eine entsprechende Längsnut des eisernen Schwingbalkens aufgeschoben und zu Abschnitten 23 aneinandergereiht. Der eiserne Schwingbalken 4 wird von hohlen; Säulen 20 getragen, die auf der Länge des Schwingbalkens so verteilt sind, daß je zwei Säulen auf einen Abschnitt entfallen. Der Deckel 18 des Ofens ist entsprechend der Anzahl der Abschnitte 23 seiner Länge nach unterteilt, so daß jeder Abschnitt durch Abheben des entsprechenden Teiles 24 des Ofendeckels 18 gemeinsam mit dem Heizkörper13 herausgehoben werden kann. Durch Abheben der Deckel 16 des Abschnittes können auch die Heizkörper 13 allein herausgenommen werden.The continuous iron swinging beams 4 are hollow, as in the main part ceramic support bodies 5 for the electrical heater 13 are provided. These ceramic Support body 5 of limited length are now with their dovetail-like The foot is pushed onto a corresponding longitudinal groove in the iron oscillating beam and strung together to form sections 23. The iron swing beam 4 is hollow; Supported pillars 20, which are distributed along the length of the vibrating beam that two each Columns are omitted on one section. The lid 18 of the oven is corresponding to the number of sections 23 divided along its length so that each section is lifted off of the corresponding part 24 of the furnace lid 18 together with the heating element 13 can be lifted out. By lifting the cover 16 of the section can also the radiators 13 are taken out alone.
Wird ein Teil des Ofens als Abschreckoder Kühlkammer verwendet oder wird dem Glühofen eine solche, angeschlossen, so werden die keramischen Träger auf dem Schwingbalken statt mit Heizkörpern mit Kühlrohren ausgerüstet. In diesem Falle dienen die hohlen Tragsäulen 20 für die Zu- bzw. Ableitung des Kühlmittels, ζ. R.Wasser. Luft usw. Auf diese Weise kann das Glühgut bei seinem Durchgang durch die Kühlkammer genau nach einer vorgeschriebenen Abkühlungskurve gekühlt werden.If part of the furnace is used as a quenching or cooling chamber, or is used as a Annealing furnace is connected, so the ceramic supports are placed on the vibrating beam equipped with cooling pipes instead of radiators. In this case the hollow support columns 20 for the supply and discharge of the coolant, ζ. R.Water. Air, etc. In this way, the material to be annealed can with its Passage through the cooling chamber exactly according to a prescribed cooling curve be cooled.
Der Durchgangsofen kann auch als Blankglühofen verwendet werden, wenn unterhalb der Schwingbalken 4 eine abdichtende Platte 21 angeordnet ist, die das Ofeninnere von dem unteren Antriebsraum abschließt. I'm diesen Abschluß gasdicht zu machen, sind die aus der Platte 21 hinaustretenden Säulen 20 in Flüssigkeitstassen 22 getaucht, so daß dasThe through furnace can also be used as a bright annealing furnace if below the vibrating beam 4 a sealing plate 21 is arranged, which the furnace interior of closes off the lower drive compartment. In the To make this closure gas-tight, the columns 20 protruding from the plate 21 are immersed in liquid cups 22 so that the
