Definitions

  • the invention relates to a device for removing with simultaneous turning of cut hot strand sections from outlet roller tables of a multi-strand casting system for steel onto a laterally arranged cooling bed with the aid of pivoting levers provided with sensors for the strand sections, which sensors have support surfaces forming an angle with one another.
  • strand sections are individually removed from the run-out roller tables by means of pivotable levers and transferred to a higher lying cooling bed.
  • the cooling bed grate is extended to above the roller tables and has flaps that can be swiveled for each strand, which are pushed up by the individual strand sections during the swiveling-up process and thereby open the way to the grate for the individual sections.
  • the sections are guided along curved guides leading into the cooling bed level onto the cooling bed grille, whereby they are turned through 90 °.
  • a cooling bed pusher then shifts the sections in the discharge direction.
  • This device has the disadvantage that a separate pivoting mechanism is required for each strand, which, like the additional cooling bed pusher, makes the system more expensive and, moreover, prone to failure.
  • a first transverse transport device consisting of an endless transport chain, which opens into a cooling bed arranged to the side of the discharge device.
  • the cut sections are individually pivoted downwards - due to the design of the sensors, they rotate by 90 ° C - and placed on the stationary cross conveyor belt, which then moves the strand towards the cooling bed.
  • the present invention seeks to avoid the disadvantages outlined above. It is therefore an object of the invention to provide a structurally simple device of the type mentioned, with which the cut-off strand sections turned 90 ° can be conveyed functionally reliably from the run-out roller tables directly onto the cooling bed.
  • transducers are provided for receiving the strand section or sections lying away from the cooling bed, that the axis of rotation of the pivoting levers is below the level of the cooling bed approximately in the middle between the cooling bed and the roller table furthest away from it
  • Lever flanks facing the cooling bed for pushing off the strand section closest to the cooling bed are designed in an arc shape and that the roller table closest to the cooling bed is provided with a chute falling in a partial area and opening into the cooling bed plane.
  • the rotation of the individual strand sections causes the strand ends spread by the shearing process to reach a vertical end position, as a result of which the strand sections come to lie flush next to one another and disadvantageous bending during pushing can be avoided. Additional turning devices for the strand sections are not necessary.
  • the invention can be further developed in that the pivot levers are each provided with a pivot joint which enables the pivoting lever head to tilt. This enables the pivoting lever to be pivoted back even if subsequent strand sections again partially extend into the pivoting region of the pivoting lever. This enables a shortening of the compensation distance for the strands running at different times.
  • Fig. 1 and Fig. 2 by arrows 31 and 32, the direction of exit of strands of a two marked billet system.
  • Scissors 3, 4 are arranged downstream of compensating roller tables, the driven rollers 5, 6 of which accelerate the strand sections into a discharge device.
  • This discharge device 7 is composed of outlet roller tables 8, 9 provided with non-driven rollers 17 and a swivel lever mechanism arranged between the roller tables 8, 9.
  • This consists of three swivel levers 11 fastened on a common axis of rotation 10 and a slide 13 extending from the roller table 8 to a cooling bed 12, which is arranged on the left in the casting direction and consists of several segments and opens into the cooling bed plane.
  • the cooling bed 12 is located with the roller tables 8 , at the same level.
  • the axis of rotation 10 is located below the cooling bed level approximately in the middle between the starting area of the cooling bed 12 and the roller table 9 which is more distant from it.
  • the supports of the cooling bed are marked with reference number 14.
  • Fixed stops 15, 16 at the end of the run-out roller tables 8, 9 are provided with switches, not shown. After actuation of both switches by strand sections 1 ', 2', the pivoting device is moved in the direction of the cooling bed 12 with the aid of a piston-cylinder unit 18 flanged to one of the levers 11.
  • the support surfaces 20 of the pivoting levers 11 provided with sensors 19 lift the strand section 2 'further away from the cooling bed 12 from the outlet roller table 9 and carry them in the direction of the cooling bed 12.
  • the strand section 1 ′ lying on the roller table 8 is pushed off the roller table 8 with the aid of curved lever flanks 21 and conveyed onto the cooling bed 12 via a slide 13.
  • FIG. 2 Details of the swivel mechanism and the sequence of movements during the swiveling are shown in FIG. 2, in which one of the swiveling levers 11 is shown in dash-dotted lines at different times during the swiveling.
  • the position of the axis of rotation 10 approximately in the middle between the cooling bed 12 and the more distant roller table 9 below the common level ensures a pivoting range from the roller table 9 to the cooling bed 12.
  • the lever ends run through an arcuate path 28 due to the low position of the axis of rotation, the apex 22 of which, that is the imaginary intersection with the vertical through the axis of rotation 10, lies above the roller table level.
  • the swivel levers 11 can have a tilt joint 28 'in an upper part, which ensures that the levers 11 swivel back even in the event that strand sections already protrude into the outlet roller tables again.
  • the swivel lever head 27 is tilted in the direction of arrow 29 when it comes into contact with the strand section and is then pulled into its original position by a spring mechanism (not shown).
  • a tilting device allows the run-out roller tables to be shortened, since the respective position of the swivel mechanism does not have to be taken into account with regard to the conveying out of further strand sections.
  • the discharge device described for two strands is also conceivable for three strand sections.
  • a further transducer with two bearing surfaces forming an angle with one another is provided at the end of the pivot lever.
  • the design of the lever flanks for pushing off the third strand section remains unchanged.
  • the position of the swivel axis, the inclination and length of the transducer surfaces must be matched to the respective construction.
  • plants can be equipped with a multiple of two or three strand numbers. It is optional whether the additional cooling beds required depending on the number of strands are arranged one behind the other in the strand running direction or opposite one another.
  • the cooling bed and the roller tables have the same level. At different levels, the position of the swivel axis and the length of the support surfaces must be coordinated so that a swivel area between the furthest roller table and the cooling bed is ensured.
  • the invention can also be used in blooming plants.
  • the number of swivel levers to be provided for each device must be matched to the length of the strand sections and the strand weight.
  • the common swivel axis can be raised and lowered so that when the lever swings back, the vertex of the swivel path comes to lie below the roller table level. A pivoting back despite strand sections located on the roller tables is thus made possible, which is why a long compensation section can be dispensed with.
