Description
Verfahren zum Glühen von Knüppeln in einem Wärmofen Das Wärmen von Knüppeln geringen Querschnittes macht in den bis jetzt üblichen und bekannten Stoßöfen. große Schwierigkeiten, besonders dann. wenn es sich um große Leistungen handelt. Die kleinen Knüppel schieben sich beim Vorwärtsbewegen übereinander, wodurch große Störungen entstehen. Sie müssen dann von Hand weitergerollt werden, da ein Vorstoßen mittels Blockdrücker nicht mehr möglich ist. Weitere Nachteile bestehen darin, daß die Knüppel durch das dichte Aneinanderliegen ungleich erwärmt auf dem Schweißherd ankommen, wo sie zwecks gleichmäßiger Durchwärmung noch längere Zeit liegen müssen und Zeitverluste entstehen, die Verringerung der Leistung bedingen.Method of annealing billets in a heating furnace The heating of Billets with a small cross-section are used in the pusher-type furnaces that have been customary and known up to now. big trouble, especially then. when it comes to great achievements. The small sticks slide over each other as they move forward, creating large ones Disturbances arise. They then have to be rolled further by hand, as an advance is no longer possible using a block handle. Other disadvantages are that the billets are unevenly heated on the welding hearth due to the close contact with one another arrive where they have to lie for a long time in order to warm up evenly and time losses occur, which cause a reduction in performance.
Zur Behebung dieser Mängel ist vorgeschlagen worden, die Knüppel auf einem wagenähnlichen Gestell, das mittels Ketten o. dgl."hin und her gezogen wird, durch den Ofen zu fördern. Diese Einrichtung erfordert ein umständliches, unter dem Feuerbetrieb leidendes Antriebswerk. Ferner ist ein kontinuierlicher Durchsatz des Knüppelmaterials nicht möglich, weil nach jeder Charge der. Wagen durch den Ofen leer zurückgezogen. werden muß. Auch ein langsamer Vorschub der Flamme entgegen läßt sich nicht durchführen, da der -Wagen während der Erwärmung des Materials im Ofen stillstehen muß, damit der Ofen an beiden Enden geschlossen gehalten werden kann. Der am einen oder anderen Ende des Ofens ein-oder ausfahrende Wagen würde dieses Abschließen verhindern.To remedy these shortcomings, it has been proposed to keep the sticks up a carriage-like frame that is pulled back and forth by means of chains or the like, to promote through the oven. This setup requires a cumbersome, taking engine suffering from fire operation. Furthermore, there is a continuous throughput of the billet material is not possible because after each batch the. Car through the Oven withdrawn empty. must become. Also a slow advance towards the flame cannot be carried out because the car is in the Oven must stand still so that both ends of the oven are kept closed can. The car going in or out at one end or the other of the furnace would prevent this from completing.
Die Erfindung vermeidet diese Übelstände dadurch, daß ein Stoßofen mit Blockdrücker auf seiner Herdsohle Rinnen erhält und so betrieben wird, daß aus einzelnen Stäben bestehende Gleitkörper, auf denen.die Knüppel ruhen, in den Rinnen lose hintereinander liegend mittels des Blockdrückers gemeinsam mit dem Glühgut durch den Ofen gefördert werden.The invention avoids these inconveniences in that a pusher furnace with block pusher on his hearth gutters and is operated so that from individual rods existing sliding bodies, on which the billets rest, in the grooves Lying loosely one behind the other by means of the block pusher together with the material to be annealed be conveyed through the furnace.
Dieses Verfahren bietet die. Möglichkeit eines kontinuierlichen Betriebes, wobei die Gleitkörper mit den Knüppeln vom Schweißherd des Ofens abgezogen werden. Eine Rückförderung zur Ofenbeschickseite ist nicht erforderlich, da als Gleitkörper Stäbe oder Knüppel beliebiger Form und Größe, also Abfallmaterial, aber auch Wärmgut, verwendet werden kann.This procedure offers the. Possibility of continuous operation, whereby the sliding bodies with the billets are withdrawn from the welding hearth of the furnace. A return to the furnace charging side is not necessary, as it acts as a sliding body Bars or billets of any shape and size, i.e. waste material, but also heat material, can be used.
Die kleinen Knüppel werden z. B. in ein geeignetes Gestell, das- zweckmäßig aus zwei Böcken besteht, gelegt und mittels dünnem Draht an beiden Enden zusammengebunden, wie dieses aus A_ bb. 2 ersichtlich ist. Diese Bündel werden- auf Stäbe c gelegt, die lose hintereinander liegend mittels des Blockdrückers durch Druck gegen die letzten Stäbe über die Rinnen-a der Flamme entgegen zum Schweißherd gedrückt werden. Zweckmäßig legt man auf je einen Stab rechts und links ein Bündel Knüppel b, so daß zwischen zwei Bündeln die Flamme durchstreichen kann, wobei eine große Materialoberfläche der Flamme ausgesetzt ist.The little sticks are z. B. in a suitable frame that is appropriate consists of two trestles, placed and tied together at both ends with thin wire, like this from A_ bb. 2 can be seen. These bundles are placed on bars c, the loosely one behind the other by means of the block pusher by pressing against the last rods are pressed over the grooves-a of the flame towards the welding hearth. It is advisable to put a bundle of sticks b on each stick on the right and left, see above that between two bundles the flame can pass through, with a large material surface exposed to the flame.
Die Rinnen werden zweckmäßig auf wassergekühlte Rohre d oder Hohlbalken gelegt, wodurch sie gekühlt werden.The channels are expediently on water-cooled pipes d or hollow beams laid, whereby they are cooled.
Die Gleitkörper c werden nach .Absturz auf den Schweißherd herausgezogen und können weiter benutzt werden. Entsprechend dem Vorschub der Gleitkörper werden immer neue Gleitkörper zur Aufnahme von Knüppeln angelegt, so daß sich ein kontinuierlicher Betrieb ergibt.The sliding bodies c are pulled out after .Afall on the welding hearth and can still be used. According to the advance of the sliding body always new sliding bodies created to accommodate billets, so that a continuous Operation results.
Nach Abb. 3 und 4 kann man die Knüppel auch gitterförmig oder schräg 'auf den Gleitkörpern aufschichten, so daß sie auch hier von allen Seiten von der Flamme oder Strahlwärme bestrichen werden und dadurch eine große Leistung erzielt wird. Diese Anordnung hat " den weiteren Vorteil, daß ein Zusammenschweißen der Stäbe verhindert wird.According to Fig. 3 and 4, the billets can also be latticed or at an angle 'on the sliding bodies so that they are also here from all sides of the Flame or jet heat can be coated and thereby achieved a great performance will. This arrangement has "the further advantage that welding together the Rods is prevented.
