Definitions
- the invention relates to a walking beam conveyor for a continuous furnace for heating aluminum bars with walking and fixed beams that run across wear bar supports that can be swiveled to a limited extent.
- Aluminum ingots are used to improve ductility subjected to casting, predominantly in Continuous furnaces equipped with walking beam conveyors for the aluminum bars are.
- These walking beam conveyors have fixed beams running in the conveying direction and between these fixed beams parallel walking beams, which are like the fixed beams Bar supports to accommodate the aluminum bars running across the bars wear.
- the aluminum bars are replaced by the Lifting beam lifted from the bar supports of the fixed beam and onto the in Direction of conveyance the next row of supports of the fixed beams, before the walking beams below the aluminum bars in the starting position for the next one Funding step can be moved back. Through unavoidable relative movements it comes between the aluminum bars and the bar-fixed bar supports to aluminum deposits on the bar supports.
- the bar supports have already been proposed not to be rigidly connected to the beams, but on the beams to be swiveled to a limited extent, namely transversely to the longitudinal direction of the beam, see above that the bar supports in their swivel position to the respective course of the Align aluminum bars.
- the associated reduction in Relative movement leads in connection with a more even load to delay the deposition processes.
- the bar supports the deposits must be removed from the beams not be sanded in the confines of the furnace space, so that overall noticeable improvements in the maintenance of these walking beam conveyors result, although the replacement of the ingot pads continues with a large one Workload remains connected.
- the invention is therefore based on the object of a walking beam conveyor for a continuous furnace for heating aluminum bars at the entrance Described kind so that the due to aluminum deposits Maintenance work required on the ingot supports is much easier can be.
- the invention solves the problem in that the bar supports have insert pieces for the aluminum bars that can be inserted into recesses.
- the Bar supports consist of a frame body, one on the corresponding Beams pivotally mounted over a cylindrical rolling surface Supporting body for a support piece enclosed by the frame body.
- the load on the support pieces by the aluminum bars is immediately on the support body and transfer it from this to the beam.
- the support body is pivotally mounted on the beam via a cylindrical rolling surface, the support body resembles the support piece on the respective bar profile while avoiding edge pressures, resulting in an even pressure load of the support piece.
- This support piece is put together enclosed with the support body from the frame body, which is thus a lateral Support for the support piece with the effect that a form stability flow of the material of the support piece impairing the support piece is prevented against the frame body when a material with correspondingly lower strength properties are used.
- the frame body secures the position of the support piece and the support body compared to the bar and is therefore immovable on the bar set.
- the frame body can use the bars laterally Form cross-game side cheeks with those running across the bars Elongated holes for receiving mounting bolts passing through the beams are provided.
- These mounting bolts result in a simple, detachable Connection between the frame bodies and the beams.
- it must be for a pivotability of the frame body in the scope of the rolling motion of the support body on the beam. This is due to the side Game between the side panels of the frame body and the beam as well by providing elongated holes in the side cheeks to accommodate the Bracket bolt reached.
- the walking beam conveyor shown consists in a conventional manner alternately arranged, parallel walking beam 1 and fixed beam 2, the saddle-shaped Wear bar supports 3 for aluminum bars 4 that have a roller table 5 across the beams 1, 2 through an oven door 6 into the continuous furnace 7 be promoted.
- the walking beam 1 which is raised with the help of supports 8 and can be adjusted in the conveying direction 9
- the walking beam 1 are then below the Aluminum bars 4 conveyed back to the starting position to a new one Funding step to be able to begin.
- the saddle-shaped bar supports 3 of the lifting and fixed beams 1, 2 have 2 and 3, a support piece 10 for the aluminum bars 4, that is inserted into a recess 11 of the ingot support 3.
- the recess 11 is obtained by a frame body 12, which overlaps the respective beams 1 and 2 with side cheeks 13.
- Sidewalls 13 are elongated holes 14 extending transversely to the beams 1 and 2, respectively provided for receiving a mounting bolt 15 which the respective beam 1 or 2 and the bar support 3 opposite the bar 1 or 2 axially.
- the weight load of the support pieces 10 by the aluminum bars 4 is not over the frame body 12 according to the embodiment, but removed via a support body 16 on the beam 1 or 2.
- This Support body 16 forms a cylindrical rolling surface 17, over which it is on the supports respective bars 1 or 2.
- the support body 16 can therefore cross to Bars 1 and 2 are pivoted to adjust the support piece 10 on the respective course of the aluminum bar 4 to be accommodated. Since the support body 16 with the support piece 10 together from Frame body 12 is enclosed, the frame body 12 with the support body 16 can be pivoted. This is through the elongated holes 14 for reached the mounting bolt 15 provided that between the Sidewalls 13 and beams 1 and 2 have sufficient movement is available.
