Definitions

  • the invention relates to a cooling element for a melting furnace, in particular an electric arc furnace having the features of patent claim 1.
  • DE 44 46 542 A1 describes a furnace vessel for a DC arc furnace with a heat-resistant wall, which consists in the area above the slag line range of a plurality of water-cooled wall segments made of steel. These wall segments are attached to a support structure. At least one of the wall segments consists of non-magnetic steel or copper and is preferably arranged on the side of the furnace vessel opposite the power supply device.
  • the individual wall segments comprise horizontally extending tubes made of non-magnetic steel, which are not arranged close to each other, but spaced apart in the vertical direction and by means of metal strips of the same material as the tubes connected to each other, for example, welded. The remaining spaces between the tubes are filled with refractory before or after installation of the wall segment.
  • cooling tube coils may be provided on the side facing the furnace center with projections, preferably nubs, pins, ribs or the like, in order to promote the adhesion of refractory material.
  • cooling panels made of steel and / or copper pipes.
  • the booth also includes cooling panels with copper pipes with so-called fin profiles.
  • This is a profile shape in which the finned webs (fins) are formed on the copper pipes, which allow better adhesion of the refractory lining.
  • additional anchors are superfluous, which are partly additionally used in surface smooth, circular tubes.
  • these tube constructions are provided with a steel back plate. Usually, this is welded to a pipe construction. The welding can also be done indirectly by welding special receptacles to the cooling tubes, which in turn are bolted or welded to the steel plate.
  • the present invention seeks to provide a cooling element for a melting furnace with a cost-effective connection between the at least one cooling tube and a cover plate connected to the cooling tube.
  • the cooling element according to the invention for a melting furnace provides in a known manner a cover plate, which may also be referred to as a support plate or base plate. As a rule, it is made of steel. At least one cooling tube is attached to this cover plate. Under a cooling tube may be a cooling tube to be understood, which runs in Meanderform. Thus, essentially the entire cover sheet can be covered, although it has larger dimensions than the cooling pipe.
  • the at least one cooling tube has a bead on its side facing the cover plate, via which it is connected to the cover plate.
  • the bead on the cooling tube increases the distance between the cover plate and the tubular part of the cooling tube. This spacing brings with it considerable advantages, both in terms of the possibilities of attachment and the security of the attachment.
  • Manufacturing technology the bead advantageously forms a uniform unit of material with the cooling tube. Preferably, therefore, it is a bead, which is formed in the extrusion process.
  • the bead therefore preferably extends in the longitudinal direction of the cooling tube.
  • the bead can therefore preferably without a further post-processing have constant width. Additional joining techniques for attaching the bead on the cooling tube omitted.
  • the bead has the particular advantage that a screw connection between the cooling tube and the cover plate can be realized, without causing the wall thickness of the cooling tube is weakened. It is understood that the bead for a screw must have a sufficient sizing. In particular, the bead must be so large that in relation to the cooling tube radially oriented threaded receptacle can be formed in it. Since such a threaded receptacle should not weaken the geometry of the tube, the depth of the threaded receptacle is preferably smaller than the height of the bead measured in the region of the central longitudinal axis of the threaded receptacle.
  • the bead must be wide enough to be sufficiently resistant to forces transmitted to the bead via a threaded connection.
  • the width of the bead should therefore be in a ratio of 1, 5 to 2.5 to the diameter of the threaded receptacle.
  • cooling tubes preferably consist of copper or a copper material which has a lower strength than the cover plate, which preferably consists of steel, it is provided in an advantageous development that threaded sleeves are inserted into the threaded bores.
  • the threaded sleeves can transmit higher forces compared to the actual screw due to their larger diameter.
  • the screw can be done either by screws, which are screwed after the positioning of the tube to the cooling plate from the furnace outer side through the cover plate into the threaded holes in which threaded sleeves are optionally arranged.
  • stud bolts can be attached to the bead, these studs are passed through openings in cover plates and fixed there by nuts.
  • a cohesive connection by means of such a bead has the advantage that greater security against leaks in comparison to an immediate welding of the pipe wall with the steel plate.
  • the heat-affected zone during welding is located by the bead at a greater distance from the coolant-conducting part of the cooling tube. Thermally induced microstructural changes do not affect the strength or even the tightness of the coolant-conducting part of the cooling tube.
  • the weld may be made more durable on a flat surface of the bead, as opposed to the curved surface of a pipe.
  • the cooling tube has on its side remote from the bead at least one extending in the longitudinal direction of the cooling tube web, a so-called fin.
  • a so-called fin Preferably, two webs are provided which are mutually arranged at an angle of 30 to 90 °. Preferably, the angle is 60 °.
  • Refractory material can adhere better and more permanently over these webs.
  • the webs in combination with the bead arranged on the opposite side also have the advantage that the material used during the extrusion is distributed more uniformly over the circumference of the entire cooling tube. This is production technology advantageous.
  • the cooling elements according to the invention are preferably used above the slag level in the wall region of a furnace vessel of an electric arc furnace.
  • the cooling elements according to the invention can also be arranged in the region of the lid and an exhaust pipe of the furnace vessel.
  • Figure 1 is a perspective view of a cooling element (detail);
  • FIG 2 is an enlarged view of the cooling element of Figure 1 and
  • FIG 3 shows a sectional view through a cooling tube on a cover plate.
  • FIG. 1 shows a perspective view of a small portion of a cooling element of a melting furnace, not shown, in particular an electric arc furnace.
  • a cover plate 2 and a below the cover plate arranged cooling tube 3 is shown.
  • the cover plate 2 is substantially larger and forms a wall segment of a furnace vessel. This wall segment is located in the installed position above the melting mirror.
  • the cooling tubes 3 face the furnace inside the melting furnace. They are flowed through in a manner not shown by a coolant. In addition, they are also surrounded in a manner not shown by a refractory material to protect them from the prevailing in the electric arc furnace temperature.
  • the special feature of the cooling element according to the invention is the nature of the design of the cooling tube 3 in connection with the attachment.
  • FIG. 2 shows that the cooling tube 3 is circular, but in its upper in the image plane, d. H. the cover plate 2 side facing a continuous, extending in the longitudinal direction of the cooling tube 3 bead 4 has.
  • a plurality of threaded receptacles are formed, which are also spaced apart in the longitudinal direction of the cooling tube 3 to each other.
  • a threaded sleeve 6 is inserted, in turn, a screw 7 engages, which are formed through through holes in the cover plate 2.
  • the screws 7 are countersunk screws which do not protrude beyond the outside or surface of the cover plate 2 in the installed position.
  • two webs 8, 9 are arranged on the side of the cooling tube 3 facing away from the cover plate 2. The webs 8, 9 are used for improved connection of a refractory material not shown with the cooling pipe. 3
  • FIG. 3 shows that the webs 8, 9 are at an angle W of 60 ° to one another and have approximately the same wall thickness as the tubular section of the cooling tube 3.
  • the threaded receptacle 5 in the bead 4 has a depth T which is less than or equal to the height H1 of the bead.
  • the depth T of the threaded receptacle 5 is 18 mm at a corresponding height H1 of the bead 4.
  • the threaded receptacle 5 has a diameter of 20 mm for receiving a threaded sleeve M20 x 1, 5 with an internal thread M16 x 2.
  • a width B of the bead 4 of 40 mm results on both sides of the threaded receptacle 5 a remaining wall thickness of 10 mm.
  • the tubular portion of the cooling tube has a wall thickness of 12 mm.
  • the outer diameter is 89.8 mm.
  • the two webs 8, 9 are radially from the tubular portion of the cooling tube 3 from. The webs 8, 9 are about twice as high as they are wide.
  • the cover plate 2 has a thickness of preferably also 12 mm.
