Abstract
Description
Die Erfindung betrifft einen Wellanker für Feuerfestmaterial nach dem Oberbegriff des Anspruchs 1.The invention relates to a corrugated anchor for refractory material according to the Preamble of claim 1.
Wellanker aus einem Rundstahl, der im wesentlichen V-förmig gebogen ist und einen Fuß aus parallel zueinander verlaufenden Abschnitten aufweist, während die sich vom Fuß auswärts erstreckenden Schenkel gewellt sind, werden in Kraftwerksanlagen zum Verankern von Feuerfestmaterial verwendet und unter Verwendung eines keramikrings auf entsprechende, wärmebeaufschlagte Flächen von Wärmetauschern od.dgl. geschweißt, die mit einer Schutzschicht aus Feuerfestmaterial zu versehen sind.Corrugated anchors made from a round steel bar that is essentially V-shaped and has a foot made of parallel sections, while the thighs extending outward from the foot are waved in Power plants used for anchoring refractory material and under Use a ceramic ring on appropriate, heat-treated surfaces of heat exchangers or the like. welded out with a protective layer Refractory materials are to be provided.
Allerdings ist infolge der Umbiegung des Rundstahls im Fußbereich des Wellankers der Fuß zu breit, um damit Rohre oder zwischen Rohren befindliche Flossen von Wärmetauscherkesseln od.dgl. zu bestiften.However, due to the bending of the round steel in the foot area of the Wellankers the foot too wide to allow pipes or in between pipes Fins of heat exchanger boilers or the like. to pin.
Aufgabe der Erfindung ist es, eine Möglichkeit zur Bestiftung von Rohren oder zwischen Rohren befindlichen Flossen von Wärmetauschern mit wellenförmigen Verankerungen für Feuerfestmaterial zu schaffen.The object of the invention is to provide a way of pinning pipes or fins of heat exchangers located between pipes to create wavy anchors for refractory material.
Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is according to the characterizing part of the claim 1 solved.
Dadurch, daß die parallel zueinander verlaufenden Abschnitte des Fußes zu einer verringerten Breite mit einer planen Anlagefläche der Abschnitte aneinander kaltverformt sind, läßt sich der Fuß in einen Keramikring einsetzen, der mit der Außenwandung eines Rohrs beim Aufsetzen hierauf einen genügend kleinen Spalt bildet, so daß ein problemloses Verschweißen des Wellankers mit dem Rohr an beliebiger Stelle möglich ist. Außerdem läßt sich der für einen derartigen Fuß benötigte Keramikring auch auf eine Flosse zwischen zwei Rohren aufsetzen, so daß auch dort ein Anschweißen des Wellankers problemlos erfolgen kann.The fact that the mutually parallel sections of the foot to a reduced width with a flat contact surface of the sections against each other are cold-formed, the foot can be inserted into a ceramic ring, which with the Outside wall of a pipe when placed on it a sufficiently small gap forms, so that a problem-free welding of the corrugated anchor to the pipe anywhere. In addition, it can be used for such a foot Place the required ceramic ring on a fin between two pipes, see above that the corrugated anchor can also be welded on there without problems.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are as follows Description and the dependent claims.
Die Erfindung wird nachstehend anhand von in den beigefügten Abbildungen
dargestellten Ausführungsbeispielen näher erläutert.
Der in Fig. 1 dargestellte Wellanker besteht aus einem Rundstahlstück, das
insbesondere einen Durchmesser von 6 mm besitzt. Das Rundstahlstück ist im
wesentlichen V-förmig gebogen und besitzt einen Fuß 1 aus parallel zueinander
verlaufenden Abschnitten 2 sowie zwei sich vom Fuß 1 V-förmig auswärts
erstreckende Schenkel 3, die gewellt sind, und zwar insbesondere nicht nur in einer
Ebene, sondern dreidimensional.The corrugated anchor shown in Fig. 1 consists of a round steel piece, the
in particular has a diameter of 6 mm. The round steel piece is in
bent substantially V-shaped and has a foot 1 from parallel to each other
extending
Der Fuß 1 ist hierbei zumindestet auf einem genügend großen Teil seiner
Länge beginnend am Fußende in seiner Breite geringer als der doppelte
Durchmesser des Rundstahlstücks ausgebildet, indem die parallel zueinander
verlaufenden Abschnitte 2 des Fußes 1 zu einer verringerten Breite mit einer planen
Anlagefläche 4 der Abschnitte 2 aneinander kaltverformt sind. Wie aus Fig. 2
ersichtlich, besitzt der Fuß 1 eine im Schnitt im wesentlichen ovale Form mit einer
beispielsweise von 12 mm auf beispielsweise 9,5 mm verringerten Breite, während
der Fuß 1 gemäß Fig. 3 noch weiter zu einem im wesentlichen kreisförmigen
Querschnitt eines Durchmessers von beispielsweise 7,8 mm verformt ist.The foot 1 is at least on a sufficiently large part of it
Length beginning at the foot end in width less than twice
Diameter of the round steel piece formed by the parallel to each other
Wie aus Fig. 4 ersichtlich, läßt sich der so in seiner Breite verminderte Fuß 1
des Wellankers in einem Keramikring 5 eines entsprechend geringen Durchmessers
zum Verschweißen mit einem Rohr 6 einsetzen, wobei nur ein entsprechend kleiner
Spalt zwischen der Außenwandung des Rohrs 6 und der zugewandten Seite des
Keramikrings 5 verbleibt, der ein problemloses Schweißen sicherstellt.As can be seen from FIG. 4, the foot 1 thus reduced in width can be
of the corrugated anchor in a
Wie aus Fig. 5 ersichtlich, läßt sich der so in seiner Breite verminderte Fuß 1
des Wellankers auch in einem Keramikring 5 eines entsprechend geringen
Durchmessers einsetzen, der auf eine Flosse 7 zwischen zwei Rohren 6 aufsetzbar
ist, so daß der Wellanker problemlos mit der Flosse 7 verschweißt werden kann.As can be seen from FIG. 5, the foot 1 thus reduced in width can be
the corrugated anchor also in a
