The parallel pieces of the foot are cold-formed to a reduced width with a smooth contact surface (4) of the pieces. The round steel has a diameter of 6 millimetres, and the foot has a width of at most 9.5 millimetres, such as 7.8 millimetres.

Description

Die Erfindung betrifft einen Wellanker für Feüerfestmaterial nach dem Oberbegriff des Anspruchs 1, (siehe z.B. DE 3 222 755).The invention relates to a corrugated anchor for refractory material according to the preamble of claim 1 (see e.g. DE 3 222 755).

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 of round steel, which is essentially V-shaped and have a foot made of sections running parallel to one another, while the legs extending outward from the foot are corrugated, are used in power plants for anchoring refractory material and using a ceramic ring on corresponding, heat-affected surfaces of heat exchangers or the like. welded, which are to be provided with a protective layer of refractory material.

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 base area of the corrugated anchor, the base is too wide to allow pipes or fins of heat exchanger boilers or the like located between tubes. 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 to create fins between tubes of heat exchangers with wave-shaped anchors for refractory material.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in accordance with the characterizing part of claim 1.

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.Characterized in that the parallel sections of the foot are cold-formed to a reduced width with a flat contact surface of the sections against each other, the foot can be inserted into a ceramic ring which forms a sufficiently small gap with the outer wall of a tube when placed thereon, so that problem-free welding of the corrugated anchor to the pipe is possible at any point. In addition, the ceramic ring required for such a foot can also be placed on a fin between two tubes, so 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 embodiments of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand von in den beigefügten Abbildungen dargestellten Ausführungsbeispielen näher erläutert.

  • Fig. 1 zeigt einen Wellanker in Seitenansicht.
  • Fig. 2 und 3 zeigen einen Schnitt längs der Linie A-A von Fig. 1 von zwei unterschiedlichen Ausführungsformen.
  • Fig. 4 und 5 illustrieren das Aufschweißen von Wellankern auf Rohre bzw. eine Flosse und zeigen die Anordnung vor dem Verschweißen.
The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the attached figures.
  • Fig. 1 shows a corrugated anchor in side view.
  • 2 and 3 show a section along the line AA of Fig. 1 of two different embodiments.
  • 4 and 5 illustrate the welding of corrugated anchors to pipes or a fin and show the arrangement before welding.

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, which in particular has a diameter of 6 mm. The round steel piece is essentially V-shaped and has a foot 1 made of sections 2 which run parallel to one another and two legs 3 which extend outward in a V-shape from the foot 1 and which are corrugated, in particular not only in one plane but in three dimensions.

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 formed at least over a sufficiently large part of its length beginning at the foot end in width less than twice the diameter of the round steel piece by being parallel to one another extending sections 2 of the foot 1 to a reduced width with a flat contact surface 4 of the sections 2 are cold formed together. As can be seen from FIG. 2, the foot 1 has an essentially oval shape with a reduced width, for example from 12 mm to, for example, 9.5 mm, while the foot 1 according to FIG. 3 has a substantially circular cross section Diameter of 7.8 mm, for example, is deformed.

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 Außenwändung 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 of the corrugated anchor, which is thus reduced in width, can be used in a ceramic ring 5 of a correspondingly small diameter for welding to a pipe 6, with only a correspondingly small gap between the outer wall of the pipe 6 and the facing one Side of the ceramic ring 5 remains, which ensures problem-free welding.

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 of the corrugated anchor, which is reduced in width in this way, can also be used in a ceramic ring 5 of a correspondingly small diameter, which can be placed on a fin 7 between two tubes 6, so that the corrugated anchor has no problem with the fin 7 can be welded.
