Definitions

  • the invention relates to an annealing base for bell annealers with a coil of sheet metal, in particular stacked sheets, receiving, on the nozzle of a central fan dormant edition, one arranged below that Surrounding the fan axis, heat-insulating filler and the load from the diffuser through the filler transferring to a frame part lying on the foundation Support structure, the filler part made in sheet metal gas-tight encapsulated insulating wool or the like. consists.
  • the annealing material on the support is over the annealing material and the base one up to the frame part Reached protective hood, one put through the fan then circulated shielding gas, mainly for avoidance of oxidation on the surface of the annealing material.
  • the protective hood is then covered by a heating hood, their heating device, usually gas or oil burners or electric heating elements, the protective hood heated on the outside, which in turn then the protective gas and subsequently heated the annealing material. After done The heating hood is heat-treated by a cooling hood replaced and the batch cooled.
  • the invention is therefore based on the object Eliminate deficiency and a glow plug at the beginning to create the type described, in which no cracks occur in the capsule forming the filling part.
  • the invention solves this problem in that in the sheet forming the capsule of the filling part immediately beneath the diffuser an adapted lower surface molded ring significantly in excess of the sheet thickness is by two concentric, him with the frame part sheet metal cylinders connecting the support structure forms.
  • the two concentric sheet metal cylinders mostly with the molded ring on the combustion chamber side are firmly welded from above with the same temperature as this one pressurized, all parts therefore dilate uniformly, so that there are no length differences or sliding movements can come between the individual parts.
  • the two Sheet metal cylinder and the form ring are during heating by the expansion coefficients corresponding to the materials concerned enlarged in diameter and then shrink again during cooling without there is a risk of sweat cracks or the like. bring about. Since the insulating wool or the like contained in the filling part. is elastic, none occurs during these processes Opening between the metal parts and the insulation material, which transport heat from above into the deeper ones Base area to the foundation through natural gas flows enables.
  • the lower edge the plate cylinder has cutouts and is only between welded these recesses to the frame part.
  • a frame part 2 On the foundation 1 is a frame part 2, which in turn Filling parts 3 carries. On the filling parts 3 is the diffuser 4 of a central fan 5, the Leitapparat 4 in turn a support 6 for the annealing material, usually bundles of sheet metal. Over the entire glow plug is a glow hood 7 put.
  • the guide device 4 To the load of the annealing material from the support 6 to the foundation 1, the guide device 4 is used first.
  • the filling part 3 which consists of a gas-tight sheet metal capsule and filled with insulating wool 8 is for load transfer on the frame part 2 a support structure arranged.
  • This support structure consists of one of the lower surfaces the nozzle 4 adapted in the sheet of the filler 3 embedded, relatively strong form ring 9, which by two concentric plate cylinders 10 with the Frame part 2 is connected, this sheet metal cylinder 10th both with the frame part 2 and with the form ring 9 are welded. From Fig. 2 it can be seen that the Sheet metal rings 10 have cutouts 11 at their lower edge and therefore only between these recesses 11 the frame part can be welded.
