Definitions

  • the invention relates to a corrugated anchor for refractory material according to the preamble of claim 1 (see e.g. DE 3 222 755).
  • 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.
  • the base is too wide to allow pipes or fins of heat exchanger boilers or the like located between tubes. to pin.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
