Abstract
Description
Förderrost für V~lgüteöf~nConveyor grate for V ~ oil quality ovens
In Vergüteöfen für Stahlteile werden Roste benutzt,auf denen das Glühgut durch den Ofen gefördert wird. Am Ende des Ofens wird der Rost herausgezogen,um an Luft,in Öl oder Wasser mit dem Glühgut zu erkalten.In tempering furnaces for steel parts, grates are used on which the material to be annealed is conveyed through the furnace. At the end of the oven, the grate is pulled out to to cool in air, in oil or water with the annealing material.
Der Rost ist starken Wärmespannungen unterworfen und bekommt nach kurzer Zeit Brüche,wenn er im ganzen starr hergestellt ist.The grate is subject to strong thermal stresses and is recovering breaks in a short time if it is made rigid as a whole.
Bei Wasserabschreckung wird der Rost krumm,weil die untere,zuerst ins Wasser tauchende Seite des Rostes schnell abgekühlt wird0 Gegenstand vorl. Erfindung ist ein Rost,der aus kufenförmigen Gleitschienen und dazwischen liegenden Zwischenrosten so aufgebaut ist, daß die Zwischenroste auf Stifte aufgesteckt sind,die auf den Seitenflächen der Gleitschienen stehen. With water quenching, the grate becomes crooked because the lower one, first The side of the grate that is immersed in the water is cooled quickly is a grate made up of runner-shaped slide rails and intermediate grids in between is constructed so that the intermediate grids are attached to pins that are on the Side faces of the slide rails are standing.
Die Stifte der Gleitschienen haben Gewinde,auf denen mit Muttern die Roste gehalten werden.The pins of the slide rails have threads on which with nuts the Grates are held.
Die Gleitschienen stehen beiderseits über die Rostflächen,sodaß der Rost nach der Wasserabschreckung gewendet wird und die eingetretene geringe Krümmung bei der Nächsten Abschreckung rückgängig gemacht wird. The slide rails are on both sides over the grate surfaces, so that the Rust is turned after the water quenching and the slight curvature that has occurred reversed at the next deterrent.
In beiliegender Zeichnung ist der erfindungsgemäße Rost beispielsweise dargestellt. Fig, 1 ist die Seitendarstellung und Fig.2 stellt den Rost in Draufsicht dar,wobei nur der Zwischenrost 2 im ersten Feld und ein Teil des Zwischenrostes 2 im zweiten Feld dargestellt sind. In the accompanying drawing, the grate according to the invention is for example shown. Fig. 1 is the side view and Fig. 2 shows the grate in plan view represents, with only the intermediate grate 2 in the first field and part of the intermediate grate 2 are shown in the second field.
Die Gleitschiene 1 hat beiderseits 3 Stifte 4 mit Gewinde und Muttern 5, während die außenliegende Gleitschiene 3 die Stifte 4 und sputtern 5 nur auf der zum Innern des Rostes gewandten Seite hat.The slide rail 1 has 3 pins 4 with threads and nuts on both sides 5, while the external slide rail 3 sputtered the pins 4 and 5 only the side facing the inside of the grate.
Zwischen den Gleitschienen 1 und 3 sind die Zwischenroste 2 mit den Tüllen 6 auf die Stifte 4 gesteckt und mit den Muttern 5 gehalten.Between the slide rails 1 and 3, the intermediate grids 2 are with the Nozzles 6 placed on pins 4 and held in place with nuts 5.
In Fig. 3 ist die Stelle A groß herausgezeichnet.In Fig. 3, the point A is drawn out large.
Die Zwischenroste 2 sind mittels der Stifte 4 und Muttern 5 gering beweglich verbunden,sodaß der Rost im Ganzen seine Form bewahrt. The intermediate grids 2 are small by means of the pins 4 and 5 nuts movably connected so that the grate as a whole retains its shape.
Der Zwischenrost 2 hat Tüllen 6,mit denen er auf den Stiften 4 sitzt.The intermediate grate 2 has spouts 6 with which it sits on the pins 4.
Die Tülle 6 mit ihrer langen Umfassung des Bolzens 4 verleiht dem ganzen Rost eine bessere Formhaltigkeit.The grommet 6 with its long enclosure of the bolt 4 gives the whole grate a better shape retention.
Die Trennung der Einzelroste 2 durch die Gleitschienen 1 und 3 bewirkt auch die Trennung der Wärmespannungen,die der ungetrennte gesamte Rost sonst gehabt hätte.The individual grids 2 are separated by the slide rails 1 and 3 also the separation of the thermal stresses that the whole unseparated grate would otherwise have would have.
Da die Gleitschienen 1 und 3 zu beiden Flächen der Zwischenroste 2 überstehen,kann der Rost gewendet werdenJsodaß die bei Wasserabschreckung eintretende Krümmung jeweils rückgängig gemacht wird. Since the slide rails 1 and 3 to both surfaces of the intermediate grids 2 survive, the grate can be turned so that the water quenching entering Curvature is reversed in each case.
Der erfindungsgemäße Rost ist infolge der dehnungsbeweglichen Trennung von Zwischenrosten 2 und Gleitschienen1,3 mit festen Stiften 4 und Muttern 5 formhaltig und haltbar und infolge des beiderseitigen Überstandes der Gleitschienen 1,3 wendbar Es ist ein wesentlicher Fortschritt bezüglich Roste für Vergüteöfen. The grate according to the invention is due to the extensible separation of intermediate grids 2 and slide rails 1,3 with fixed pins 4 and nuts 5 retain their shape and durable and reversible due to the overlap on both sides of the slide rails 1,3 It is a major step forward in terms of grates for tempering furnaces.
