Definitions

  • the invention relates to a cooling element as a replaceable component of an inner Arc furnace cladding.
  • the cooling element shrinks accordingly stronger on the side facing the inside of the arc furnace than on the outside. This leads to a curvature directed towards the inside of the furnace of the cooling element, which with increasing number of melting processes and the associated temperature changes increases. In practice it follows then the problem that when loading an arc furnace metal parts the protruding edges of the bent cooling elements bounce, causing considerable Damage to the cooling elements can result.
  • the invention proposes that the interior of the arc furnace facing side of the cooling element by means of towards the coolant channels extending grooves arranged in a grid-like manner in a plurality of surface segments to divide.
  • the material is not at the bottom of the grooves brought together. This requires that the bottom of the groove the limit temperature for the shrinking phenomena of about 140 ° C is not is exceeded. This requirement is met in that the bottom of the groove is close is located on the coolant channels arranged in the interior of the cooling element.
  • a polygonal, in particular hexagonal, configuration is also conceivable.
  • the grooves such as provided according to claim 5, mechanically incorporated and preferably milled are. It is advantageous to use a side milling cutter, through the grooves more targeted Contour can be generated.
  • slag splashes accumulate on each cooling element.
  • a slag layer forms from the slag splashes, which Cooling element in addition to that in the interior of an arc furnace Shields temperatures.
  • the grooves introduced are therefore supplementary to an improved slag deposit. Especially when the grooves have a smaller width at their slot mouths than at the bottom of the slot (claim 6), the slag layer can adhere well to the cooling element.
  • the cooling element is made from a raw block Forged or rolled copper or a low alloy copper alloy.
  • the Microstructure of rolled or forged copper or copper alloys denser and more homogeneous than that of cast copper plates. Still own Forged or rolled copper plates have higher strength and thermal conductivity as cast copper plates.
  • Cooling element improved cooling possible because of the grooves the surface of the side of the arc furnace facing the interior of the arc furnace Cooling element is enlarged.
  • the grooves and the coolant channels introduced into the copper plate to form the cooling element.
  • FIGS 1 and 2 show a plate-like cooling element 1, which is an exchangeable Part of an inner lining of an arc furnace, not shown is.
  • the cooling element 1 is inside the arc furnace above the Metal melt arranged.
  • grooves 3 are made at a uniform distance from each other perpendicular to the side.
  • the grooves 3 extend in the direction of inside the cooling element 1 arranged coolant channels 4. Only one of these is shown schematically.
  • the coolant channel 4 is in through a from the upper end in the image plane the cooling element 1 introduced blind hole 5 is formed and by a plug 6 tightly closed.
  • Pipe pieces 8, 9 placed for the coolant supply and removal.
  • the pipe sections 8, 9 are connected to the coolant channels 4 in a manner not shown.
  • hook-shaped fasteners 10 On the rear side 7 of the cooling element 1 are also in the lower and middle Height range arranged hook-shaped fasteners 10, through which the Cooling element 1 can be attached to the frame of the arc furnace.
  • the grooves 3 have a constant width. But it is in a further development of the invention according to FIG. 4 it is also conceivable that the grooves 3 are wider at their groove base 11 than at their groove mouths 12.
  • Figure 2 shows that in the cooling element 1, a first column 13 parallel to each other extending grooves 3 is introduced the same distance.
  • a second column 14 is formed by parallel grooves 3a running vertically in the image plane.
  • the grooves 3 and 3a delimit surface segments 15, which are square in this exemplary embodiment are.
  • the surface segments 16 of the Cooling element 1a diamond-shaped and formed by equidistant parallel grooves 17, 17a.
