Description
Durchziehofen Bei elektrischen Durchlauföfen mit frei hängendem Glühgut muß man in der Bemessung und Ausgestaltung des Glühraumes dem Durchhang des Glühgutes Rebhnung tragen. Dies geschah bisher in der Weise, daß der Glühraum entsprechend hoch gewählt wurde, oder es wurde, um die überflüssige Höhe etwas zu verringern, schräge Durchführung des Glühgutes vorgesehen. Bei dieser Konstruktion wird der Glühraum unerwünscht groß und die Entfernung der Heizwände vom Glühgut sehr verschieden.Pull-through furnace For electric continuous furnaces with freely hanging annealing material one has to take into account the sag of the material to be annealed in the dimensioning and design of the annealing space To wear rebel. This has been done so far in such a way that the glow space accordingly was chosen high, or it was chosen to reduce the superfluous height a little, inclined implementation of the annealing material provided. With this construction, the The annealing space is undesirably large and the distance between the heating walls and the material to be annealed is very different.
Gemäß der Erfindung wird .eine wesentliche Verringerung des Volumens des inneren Glühraumes bei gleichmäßig geringem Abstand der Ofenwände vom Glühgut in allen Ofenteilen dadurch erreicht, daß die Längsachse des Glühraumes dem Durchhang des Glühgutes entsprechend gebogen wird.According to the invention. A substantial reduction in volume of the inner annealing chamber with a uniformly small distance between the furnace walls and the annealing material achieved in all parts of the furnace that the longitudinal axis of the annealing chamber the slack of the annealing material is bent accordingly.
Dieser Gedanke läßt sich auf alle Arten Durchziehöfen mit elektrischer Widerstandsbeheizung anwenden. Die innere Ofenwand kann in Form einer einzigen in der Kettenlinie gebogenen Muffel ausgebildet sein, oder es wird eine Anzahl kürzerer Muffeln hintereinander zur Bildung eines kettenlinienförmig gebogenen Glühraumes zusammengestellt.This idea can be applied to all types of pull-through yards with electric Apply resistance heating. The inner furnace wall can be in the form of a single in the catenary curved muffle be formed, or there will be a number of shorter Muffles one behind the other to form an annealing space curved in the shape of a chain compiled.
Die Art der elektrischen Widerstandsbeheizung ist hierbei gleichgültig. In den meisten Fällen ist die innere Ofenwand der Heizkörperträger. Die Heizkörper können aber auch hinter der inneren Ofenwand hegen. Gleichgültig ist auch, ob die Ofeninn-enwand als ungeteilte Röhren (bezogen auf die Ebene senkrecht zur Durchlaufrichtung) oder durch Zusammenbau von einzelnen Teilen gebildet ist. Eine. besonders einfache und zweckmäßige Konstruktion ist möglich durch Verwendung von bekannten dünnwandigen ovalem Muffeln aus keramischer- Masse mit darin eingebetteten Heizwiderständen, welche das Glühgut allseitig umgeben. Diese Muffelröhren lassen sich ähnlich wie Drainageröhren durch einfaches- Hintereinandersetzen jedem vorkommenden Durchhang anpassen, ohne daß sich die Ofenkonstruktion verteuert, da diese Muffeln nur an ihren Stoßstellen getragen und im übrigen nur von loser Isoliermasse umgeben sind.The type of electrical resistance heating is irrelevant here. In most cases the inner furnace wall is the radiator support. The radiators but can also lie behind the inner furnace wall. It is also irrelevant whether the Inner furnace wall as undivided tubes (based on the plane perpendicular to the direction of flow) or is formed by assembling individual parts. One. particularly simple and convenient construction is possible by using known thin-walled oval muffle made of ceramic mass with embedded heating resistors, which surround the annealing material on all sides. These muffle tubes can be similar to Drainage pipes by simply stacking each slack that occurs adapt without the furnace construction becoming more expensive, since these muffles only their joints are worn and otherwise only surrounded by loose insulating material.
In der Abbildung ist gezeigt, wie eine hintereinander angeordnete Reihe von Muffeln 1Y1, welche nur an ihren Stoßstellen S auf feuerfesten Steinmauern F aufliegen und im übrigen von losem Isolierpulver umgeben sind, dem natürlichen Durchhang des Bandes in einer Kettenlinie angepaßt ist.In the picture it is shown how one is arranged one behind the other Row of muffles 1Y1, which only at their joints S on refractory stone walls F and are surrounded by loose insulating powder, the natural one The slack of the belt is adjusted in a chain line.
