Definitions

  • the invention relates to a device for removing, with simultaneous turning, cut-to-length 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.
  • strand sections are individually removed from the feed 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 pivoted 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 arcuate, opening into the cooling bed plane guide on the cooling bed frame, whereby they are turned 90 0th 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 makes the system, as well as the additional cooling bed pusher, more expensive and, moreover, prone to failure.
  • a first transverse transport device consisting of an endless transport chain, opens out below the outlet roller table level and opens into a cooling bed arranged on the side of the discharge device.
  • swivel levers assigned to each strand rotatably mounted between roller table and cooling bed level, which are provided with sensors for pushing off the strand sections from the roller table, the cut sections are individually pivoted downwards - due to the design of the sensors they rotate by 90 ° complete - 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 described above and has as its object to provide a structurally simple device with which the cut to length strand sections can be supported by 90 o turned functionally reliable from the outlet roller conveyors directly onto the cooling bed.
  • 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 tilt joint. 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.
  • arrows 31 and 32 respectively indicate the direction in which strands of a two-strand billet system run out.
  • 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 discharge 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 , 9 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.
  • FIG. 2 Details of the pivoting mechanism and the sequence of movements during pivoting can be seen in FIG. 2, in which one of the pivoting levers 11 is shown in dash-dotted lines at different points in time during pivoting.
  • 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, lies above the roller table level. This makes it possible to lift off the roller table 9 in order to perform the pivoting movement of the strand section 2 '.
  • the strand section 2 ' is lifted from the roller table 9 by the approximately horizontal sensor surface 20, which can also run obliquely, and slides during pivoting when the apex 22 is passed onto a support surface 23, the strand section lying on the sensor 19 with another side surface is coming.
  • the section 2 ' is placed on the cooling bed 12, the latter has rotated through 90 °, as a result of which the widened strand ends 26 come into a vertical position.
  • the at the end thumb-shaped contact surfaces 20 extend at the end of the swiveling path between the Cooling bed support 14 and move the sections lying on the cooling bed in the discharge direction.
  • 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 protrude again into the run-out roller tables.
  • the swivel lever head 27 is tilted in the direction of arrow 29 upon contact with the strand section and then pulled into its original position by a spring mechanism, not shown.
  • Such a tilting device allows the run-out roller tables to be shortened, since no consideration has to be given to the respective position of the swivel mechanism 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.
  • 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 or opposite one another in the strand running direction.
  • 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 contact surfaces must be coordinated so that a swivel area between the most distant 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 pivot axis can be raised and lowered so that when the lever is pivoted back, the apex of the pivot 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.
