Description

Elektrisch beheizte, für fortlaufenden Betrieb geeignete Ofenanlage mit nebeneinanderliegenden Beschickungs-, Heiz- und Abkühlräumen, deren Böden gemeinsam heb- _ und senkbar sowie vierfahrbar sind, und Verfahren zum Betriebe der Anlage In den metallurgischen Großbetrieben wurden zum Glühen von Stahl bisher vor allem Koksöfen verwendet, neuerdings kommen aber auch, insbesondere zum Blankglühen, elektrische Glühöfen auf. Der elektrische Betrieb verlangt jedoch infolge der verhältnismäßig hohen Stromkosten Einrichtungen, durch welche die Wärmeverluste auf ein Mindestmaß beschränkt werden. Zu diesen Einrichtungen gehört in erster Linie eine möglichst rasch arbeitende Beschickungsvorrichtung. Große Glühgüter besitzen nach dein Glühen einen erheblichen Wärmeinhalt, welgezogen oder cher zu Vorwärmezwecken herananderweitig ausgenutzt werden kann.Electrically heated furnace suitable for continuous operation with adjacent loading, heating and cooling rooms, their floors in common can be raised and lowered as well as four-wheeled, and procedures for operating the system In large metallurgical plants, steel has been annealed so far Coke ovens are used, but recently electric ones have also been used, especially for bright annealing Annealing furnaces. The electrical operation requires, however, due to the relatively high electricity costs facilities, through which the heat losses to a minimum be restricted. These facilities include, first and foremost, one as possible fast loading device. Have great incandescent goods after they have glowed a considerable amount of heat, drawn or approached for preheating purposes can be exploited.

Die Beschickungsvorrichtung nach der Erfindung wird den angegebenen Anforderungen gerecht. Sie betrifft eine elektrisch beheizte, für fortlaufenden Betrieb geeignete Ofenanlage finit nebeneinanderliegenden Beschickunig#-, Heiz- und Abkühlr<iumen, deren Böden gemeinsam senk- und hebbar sowie in ihrer tiefsten Stellung seitlich vierfahrbar sind. Erfindun-genuiß besteht die Anlage aus fünf in einer Reilie hintereinander angeordneten Räumen, und zwar in der Reihenfolge: 1. Be>cliicktuig:rauni, 2. hühlkamnier, 3. Glühraum, .l. Beschickung.rauni, 3. hühlkaminer. In der Zeichnung ist ein Ausführungsbeispiel für die Erfindung dargestellt. Danach ruhen drei Ofenböden e auf einer gemeinsamen, heb- und senkbaren Ofenplattform 1, ferner ist ein Glühraum a mit den Heizkörpern k und sind zwei Abkühlöfen b, und b=-mit den zur Ausnutzung der Abwärme dienenden Gebläsen dl und d. sowie zwei Beschickungsplätze c, und c_ vorhanden. Die Ofenböden e mit dem Glühgut g ruhen auf einem Fahrgestell f, das auf Schienen i senkrecht zur Ofenlängsrichtung läuft und mittels hydraulischer oder motorischer Hubwerke h gehoben und gesenkt werden kann. Der Wagen f ist so lang wie drei nebeneinanderliegende Ofen und die Gleise so tief unter den Ofen angebracht, daß ein Wagen mit beschickten Ofenböden unter den Ofen hinwegfahren kann. Der Wagen f wird von der Ausgangsstellung gemäß der Abbildung zunächst um zwei Ofenteilungen nach rechts weitergeschoben, so daß der jetzt links stehende, frisch beschickte Ofenboden unter den Glühofen, a, der mittlere abgekühlte Behälter g aus dein Ofen b, an die Entnahme- und Beschickungsstelle c, und das frisch geglühte Gut aus dein Ofen a in den Abkühlofen b, gelangt; während des Glühvorganges wird der mittlere Ofenboden auf dein Platz c., entleert und frisch beschickt. Dann folgt das Glühen des auf dein mittleren Bo-len aufgebauten Gutes nach Weiterschieben des Wagens um eine einfache Ofenteilung nach links. Nach Beendigung auch dieses Prozesses wird wiederum um eine Teilung nach links verzchoben. wodurch dann wieder das in der Zeichnung dargestellte Bild der Ausgangsstellung erscheint.The loading device according to the invention meets the specified requirements. It relates to an electrically heated furnace system suitable for continuous operation, finitely juxtaposed loading, heating and cooling rooms, the floors of which can be lowered and raised together and can be moved laterally in their lowest position. According to the invention, the system consists of five rooms arranged one behind the other in a row, in the following order: 1. Click: rauni, 2. hühlkamnier, 3. glow room, .l. Charging.rauni, 3rd hühlkaminer. In the drawing, an embodiment of the invention is shown. Thereafter, three furnace floors e rest on a common, raisable and lowerable furnace platform 1, there is also an annealing room a with the heating elements k and two cooling furnaces b, and b = with the fans dl and d which are used to utilize the waste heat. as well as two loading stations c, and c_ available. The furnace floors e with the annealing material g rest on a chassis f, which runs on rails i perpendicular to the furnace longitudinal direction and can be raised and lowered by means of hydraulic or motorized hoists h. The carriage f is as long as three adjacent ovens and the rails are so deep under the oven that a carriage with loaded oven floors can pass under the oven. The carriage f is pushed from the starting position to the right by two furnace divisions, so that the freshly loaded furnace floor, now on the left, is under the annealing furnace, a, the middle, cooled container g from your furnace b, to the removal and loading point c, and the freshly annealed material from your furnace a enters the cooling furnace b ; During the annealing process, the middle floor of the furnace is emptied in place c. and freshly loaded. This is followed by the glowing of the goods built on the middle plank after pushing the cart one simple oven division to the left. After this process has been completed, it is shifted to the left by one division. whereby the picture of the starting position shown in the drawing then appears again.

Zur Verhinderung der Oxvdation und Zunderbildung beim Glühen kann in den Glüh-und Abkühlraum in bekannter Weise ein iilditterentes oder deso-_vdiereildes Gas ein--_ eführt «-erden.Can be used to prevent oxidation and scale formation during glowing an iilditterentes or deso-_vdiereildes in the annealing and cooling room in a known manner Gas in --_ introduces «- earth.

Die angeführten Beispiele sind natürlich nicht erschöpfend, vielmehr kann das der Erfindung zugrunde liegende Prinzip bei allen möglichen Ofentypen angewendet und deren Form und Zweck angepaßt «-erden. Auch die Größe und die 'Menge des zu verarbeitenden Gutes sowie die Art und Größe des zur Ver-:iigung stehenden Raumes spielen keine Rolle.The examples given are of course not exhaustive, but rather the principle on which the invention is based can be applied to all possible types of furnace and adapted to their form and purpose. Also the size and the 'amount of the too processed goods as well as the type and size of the space available does not matter.

Ferner läßt sich die beschriebene Einrichtung für Emaillier-, Brenn-, Härte-, Temper-und andere Ofen, speziell auch für Ofen der chemischen Industrie, sinngemäß anwenden.Furthermore, the device described can be used for enamelling, firing, Hardening, tempering and other furnaces, especially for furnaces in the chemical industry, apply accordingly.
