Definitions
- the invention relates to a corrugated anchor for refractory material according to the Preamble of claim 1.
- 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.
- 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.
- 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.
- 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.
- 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 sections 2 and two from the foot 1 V-shaped outwards extending legs 3 which are corrugated, in particular not only in one Level, but three-dimensional.
- 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 trending sections 2 of the foot 1 to a reduced width with a plan Contact surface 4 of the sections 2 are cold formed together.
- the foot 1 has an essentially oval shape with an average for example from 12 mm to, for example, 9.5 mm reduced width, while the foot 1 according to FIG. 3 even further to a substantially circular Cross-section of a diameter of, for example, 7.8 mm is deformed.
- the foot 1 thus reduced in width can be of the corrugated anchor in a ceramic ring 5 of a correspondingly small diameter use for welding with a tube 6, only a correspondingly small one Gap between the outer wall of the tube 6 and the facing side of the Ceramic ring 5 remains, which ensures problem-free welding.
- the foot 1 thus reduced in width can be the corrugated anchor also in a ceramic ring 5 of a correspondingly small Insert diameter that can be placed on a fin 7 between two tubes 6 is so that the corrugated anchor can be easily welded to the fin 7.
