Definitions

  • the invention relates to a charging and decharging device for heating furnaces, in particular bogie push-through furnaces and rotary hearth furnaces.
  • the positioning of the heating goods on the bogie wagon or on the benches of the rotary hearth furnaces must be at a relatively large distance so that the gripping tongs of the charging and decharging devices reach through between the individual parts of the stored heating goods and individual billets or od . dgL. can take.
  • these distances are also within the inner radius of the rotary hearth between the individual billets or dgL. must be given, this leads to an undesirably large unoccupied area of the rotary hearth, especially in the outer areas.
  • the invention is therefore based on the object of fulfilling all of these requirements simultaneously and in each case as optimally as possible both for bogie push-through furnaces and for rotary hearth furnaces.
  • This object on which the invention is based is achieved by a pivotable lifting device L.
  • the pivotable design of the lifting fork creates a direction of movement which, in addition to the longitudinal movability of the entire charging or decharging device, does not have to be designed to be movable in the additional direction of movement.
  • the support arm is preferably designed similar to a U that is open at the bottom, the lifting forks being attached to a tube rotatably mounted in the two lower ends of the U legs and with grooves on the top of the ceramic benches matched to the lifting power on the top of the bogie wagons or the lathe work together.
  • Fig. 1, 1 is generally a device for heating billets, slabs or. referred to, which consists of an actual furnace 2, are pushed through the bogie, not shown, in the direction of the arrow.
  • the bogie wagons, not shown, are loaded by a charging device 3 and unloaded again by a decharging device 4 at the end of the furnace.
  • the bogie wagons After leaving the furnace 2, the bogie wagons arrive on a transverse transfer platform 5, with the help of which they are moved transversely to their previous direction of travel and reach a return track 6.
  • This return track 6 transports the bogie wagons in the opposite direction to the direction of travel through the furnace to a transverse transfer platform 7, which moves the bogie wagons to the entrance of the furnace 2.
  • There the cycle begins again along the respective arrow directions.
  • FIG. 2 shows a cross section through the furnace 2 in the region of the charging device 3 on a larger scale.
  • the heating material 9 is transported close to the furnace 2 up to a position specified by stoppers, not shown.
  • a supporting arm 11 is arranged which is mounted in a known manner and on the roadway 1 0 longitudinally movable. The drive means for this as well as for achieving a small stroke movement of the support arm 11 are not shown for reasons of clarity.
  • the support arm 11 has the shape of a U which is open at the bottom, a tube 12 being rotatably mounted on the lower free ends of the two legs of the U and being pivotably arranged with the aid of a hydraulic cylinder 14. Together with several tines 15, the tube 12 forms a lifting fork, the tines 15 being arranged in such a way that they can cooperate with grooves 16 in ceramic banks 17 of bogie wagons 18 in such a way that they dip into these grooves 16 and transversely to the direction of travel of the bogie wagons 18 Lying KnüppeL or the like. Can grasp by a pivoting movement.
  • the height adjustability of the support arm 11 is such that when the tines 15 are swiveled up and the support arm 11 is lowered, the lowest positions of the tines 15 are above the benches 17 of the hearth trolley and that when the prongs 15 are swiveled but the support arm 11 is raised, the lowest positions of the prongs 15 are also above the benches 17 of the bogie 18 are arranged.
  • the charging or decharging device can therefore be moved without problems in these settings.
  • the entire charging machine 3 can move laterally out of the oven 2, while the bogie wagon 18 continues to clock by one division. The described cycle then begins again.
  • the newly introduced pieces are attached to the already deposited heat 9 from the outside. Because this is not done using tongs, only a small distance between the individual pieces of the heating material is required.
  • the oven is decharged in reverse the same way, the opening of the tines 15 in the decharging device 4 being oriented in exactly the opposite direction to that of the charging device 3, so that the pieces of the heat material 9 to be removed are removed from the outside and no large distance between the individual pieces is necessary here either.
  • the area of the oven 2 arranged behind the decharging device 4 has a very flat ceiling, which is brought close to the surface of the ceramic benches 17 of the bogie wagon 18, so that doors are no longer required here in order to achieve good heat tightness of the furnace.
  • the area of the furnace 2 in front of the charging device 3 is also designed accordingly.
  • lifting and lowering platforms can also be provided, in which case the return track 6 would run below the furnace 2.
  • a rotary hearth furnace is conceivable instead of the bogie push-through oven shown, in which case the hearth of the rotary hearth furnace must have annularly arranged benches and annularly arranged grooves_ corresponding to the illustrated grooves 16, into which the pivotable prongs 15 - as above described - immerse and swing out.
  • the forces to turn the tube 12 and pivot the tines 15 are ratios moderately low and the forces to move and lift the entire device are so low that they can be easily used by relatively small motors.
  • the construction of the actual charging or decharging machine is extremely simple and furthermore does not require any complex feed devices.
  • the small stroke of the entire device also simplifies the heat sealing, so that good heat insulation of the stoves can be achieved in conjunction with the pulled-down furnace ends.
