Definitions

  • the invention relates to a Hubbalkennamate for a continuous furnace for heating aluminum bars with lifting and fixed beams, which carry transversely to the bars limited pivotable bar supports.
  • Aluminum ingots are subjected to a heat treatment to improve ductility after casting, mainly in continuous furnaces equipped with lifting bar conveyors for the aluminum ingots.
  • This Hubbalken makeuper have running in the conveying direction fixed beams and parallel between these fixed beam walking beams, like the fixed bars bear bar supports for receiving the transverse to the bars extending aluminum bars.
  • the aluminum bars are lifted by the lifting bars of the bar supports of the fixed beams and placed on the next in the conveying direction edition series of hard bars before the lifting bars are moved back below the aluminum ingots in the starting position for the next conveying step. Due to unavoidable relative movements between the aluminum bars and the bar-fixed bar supports, aluminum deposits on the bar supports occur.
  • the burden of the support pieces through the aluminum ingot is transferred directly to the support body and from there to the beam. Since the support body is mounted pivotably on the beam via a cylindrical rolling surface, the support body is similar to the support piece to the respective ingot course while avoiding edge pressures, resulting in a uniform Druckbela stung the support piece brings with it.
  • This support piece is enclosed together with the support body of the frame body, thus providing a lateral support for the support piece with the effect that a dimensional stability of the support piece impairing flow of the material of the support piece is prevented against the frame body out when a material with correspondingly lower strength properties is used.
  • the frame body secures the position of the support piece and the support body relative to the beam and is therefore fixed immovably on the beam.
  • the frame body can form the beams laterally with play side cheeks, which are provided with transverse to the bars extending slots for receiving the beams passing through the support bolts.
  • This mounting bolts results in a simple, detachable connection between the frame bodies and the beams.
  • it must be ensured for a pivoting of the frame body in the scope of the rolling movement of the support body on the beam. This is achieved by the lateral clearance between the side cheeks of the frame body and the beam and by the provision of slots in the side cheeks for receiving the support bolts.
  • the Hubbalken makinger shown consists in a conventional manner of alternately arranged, parallel lifting beam 1 and fixed beams 2, the saddle-shaped bar supports 3 carry aluminum bars 4, via a roller table 5 transverse to the bars 1, 2 through an oven door 6 in the continuous furnace. 7 be encouraged.
  • the walking beam 1 which can be raised by means of supports 8 and adjusted in the conveying direction 9
  • the aluminum bars 4 are raised on the one hand by the roller table 5 and the other part of the bar supports 3 of the fixed beams 2 and further promoted by a conveying step before they by lowering the Walking beams on the next row of the bar supports 3 of the fixed bars 2 are discontinued.
  • the walking beams 1 are then conveyed back below the aluminum ingot 4 in the starting position in order to start a new conveying step can.
  • the recess 11 is obtained by a frame body 12 which engages over the respective beams 1 and 2 with side cheeks 13.
  • a support bolt 15 transverse to the beams which passes through the respective beams 1 and 2 and the billet support 3 relative to the beam 1 and 2 axially defines.
  • the weight load of the support pieces 10 through the aluminum ingot 4 is not removed via the frame body 12, but on a support body 16 on the beams 1 and 2 according to the embodiment.
  • This support body 16 forms a cylindrical rolling surface 17, via which it is supported on the respective beam 1 and 2 respectively.
  • the support body 16 can therefore be pivoted transversely to the beam 1 and 2, respectively, in order to allow adaptation of the support piece 10 to the respective course of the aluminum billet 4 to be received. Since the support body 16 is enclosed with the support piece 10 together by the frame body 12, the frame body 12 must be able to be pivoted with the support body 16. This is achieved by the slots 14 for the support bolt 15 on the premise that between the side cheeks 13 and the beams 1 and 2, a sufficient range of motion is present.
