Description

Wärm- und Glühöfen für Bleche und Platten Die vorliegende Erfindung bezieht sich auf einen Wärm- und Glühofen mit einem Rollenförderherd zum Glühen und Normalisieren von Blechen und Platten. Gemäß der Erfindung sind zwischen den Förderrollen heb- und senkbare, senkrecht stehende, fingerartige Tragstützen zum Tragen des Gutes während des Glühvorganges vorgesehen. Das Gut wird mittels des Rollenherdes zu- und abgeführt und während der Glühperiode durch Anheben der Tragstützen von den Förderrollen abgehoben.Heating and Annealing Furnaces for Sheets and Plates The present invention refers to a heating and annealing furnace with a roller conveyor hearth for annealing and normalization of sheets and plates. According to the invention are between the Conveyor rollers liftable and lowerable, vertically standing, finger-like support supports for Carrying of the goods provided during the annealing process. The good is made by means of the Roller hearth supplied and removed and during the glow period by lifting the support supports lifted off the conveyor rollers.

Um die Tragstützen heben und senken zu können, werden sie auf querlaufenden, unterhalb des Herdes liegenden Tragbalken angeordnet und die letzteren durch Hinundherbewegen von darunter befestigten keilförmigen Gleitschuhen gehoben oder gesenkt.In order to be able to raise and lower the supports, they are placed on transverse, arranged below the hearth supporting beams and the latter by moving to and fro raised or lowered by wedge-shaped sliding blocks attached underneath.

In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt.The subject of the invention is shown in an exemplary manner in the drawing Embodiment shown.

Die senkrecht beweglichen, aus feuerbeständigem Stoff bestehenden Tragstützen a, welche das Abheben des Glühgutes b von dem Rollenherd c bzw. das Tragen des Glühgutes zu bewirken haben, werden in ihrer vertikalen Verlängerung durch den Herd hindurchgeführt und ruhen unterhalb des Herdes auf den Tragbalken d, die ihrerseits mit den Rollen e auf den keilförmigen Gleitschuhen f aufliegen. Der untere Teil der Tragstützen a ist in den Sandabschlußtassen g zylindrisch geführt, so daß ein seitliches Verschieben ausgeschlossen ist. Durch Verschieben der keilförmigen Gleitschuhe f nach rechts, Fig.2, was beispielsweise durch elektrischen oder hydraulischen Antrieb geschehen kann, gleiten die Rollen e und mit ihnen die Tragstützen a auf den Gleitschuhen f senkrecht abwärts, so daß das von den letzteren getragene Glühgut b auf den Rollenherd c abgelegt wird. Beim Abheben des Glühgutes b von dem Rollenherd c erfolgt die Bewegung in umgekehrter Richtung (Heben des Wärm- bzw. Glühgutes).The vertically movable support supports a made of fire-resistant material, which lift the annealing material b from the roller hearth c or carry the annealing material, are passed through the hearth in their vertical extension and rest below the hearth on the support beam d, which in turn rest with the rollers e on the wedge-shaped sliding blocks f. The lower part of the support supports a is guided cylindrically in the sand sealing cups g, so that lateral displacement is excluded. By moving the wedge-shaped sliding shoes f to the right, Figure 2, which can be done, for example, by an electric or hydraulic drive, the rollers e and with them the supporting supports a slide vertically downward on the sliding shoes f, so that the annealing material b carried by the latter slide on the roller hearth c is put down. When the material to be annealed b is lifted from the roller hearth c, the movement takes place in the opposite direction (lifting of the material to be heated or to be annealed).

Bei dem Weg durch den Ofen liegt also das Glühgut b, je nach dem Heben und Senken der Tragstützen ac, entweder auf dem Rollenherd c (Förderstellung) oder auf den Tragstützen a (Ruhestellung) auf. Dieses wechselnde Aufliegen hat den Zweck, die Rollgangachsen c während der bis zu einer Stunde und mehr betragenden Glüh- bzw. Wärmdauer zu entlasten und einen Temperaturausgleich des Glühgutes zu bewirken.On the way through the furnace, the annealing material b lies, depending on how it is lifted and lowering of the supports ac, either on the roller hearth c (conveying position) or on the supports a (rest position). This alternating support has the purpose the roller table axes c during the annealing or to relieve heating time and to bring about a temperature equalization of the annealing material.
