Definitions

  • the invention relates to a sprue of a continuous casting and a method for their operation.
  • a cast strand is formed from a metallic melt.
  • the metallic melt is conveyed into a mold of the continuous casting plant.
  • the mold is cooled, so that in the mold, the solidification of the melt begins.
  • surface areas of the melt solidify into a so-called strand shell, which encloses a still liquid metallic core.
  • the cast strand formed in the mold is discharged through a Kokillenausgang to a so-called strand guide, transported by the cast strand and is further cooled.
  • Anfahrstrangkexcellent which each form a positive hook-shaped connection with the casting strand head, which is achieved by a tilting movement of the Anfahrstrangkopfes relative to the cast strand.
  • a connection of a starter strand head with a cast strand head is only feasible with relatively thick casting strands (eg, with a strand thickness of more than 180 mm), since a pull-out force that is too thin can not be transferred if the casting strands are too thin.
  • the cast strand is cut off from the starter strand head firmly connected to it by means of a so-called pendulum scissors. Thereafter, the Anfahrstrang is laterally deported from the cast strand and placed on a Anfahrstrangablage. Subsequently, the casting strand remaining on the starter strand is separated from the starter strand. Before the next casting, the dummy bar is again conveyed via the strand guide to the mold in the casting position (so-called "bottom feeding").
  • EP 1 249 287 A1 discloses a method and an apparatus for starting a continuous casting plant, wherein a cold strand head is connected via a tie rod with a hot strip.
  • the tie rod is provided with a hinge pin which is rotatably mounted in a cylindrical recess of the cold strand head. By pivoting the cold-rod head relative to the hinge pin, the cold-rod head can be released from the tie rod.
  • the invention has for its object to provide an improved sprue of a continuous casting and a method for their operation, wherein the sprue is particularly suitable for the formation of thin casting strands.
  • An inventive casting device of a continuous casting plant which has a mold for forming a cast strand from a metal melt filled into the mold and a strand guide for transporting the cast strand downstream of the mold, comprises a starter strand with a starter strand head, which is used to close a mold exit of the mold during a continuous casting start is formed and a first Anfahrstrangende the Anfahrstrangs forms, with a second Anfahrstrangende the Anfahrstrangs releasably connectable pull-up device for pulling the Anfahrstrangs on the second Anfahrstrangende and at least one connecting element for connecting a G cleverstrangkopfes the cast strand with the Anfahrstrangkopf.
  • a first portion of the connecting element is releasably connectable to the Anfahrstrangkopf and a second portion of the connecting element is poured during the Strangg cashbeginns in the mold in the cast strand head.
  • the detachable connection of the connecting element with the Anfahrstrangkopf is a pivot joint, which is releasable by a resulting in pulling up the Anfahrstrang pivotal movement of the Anfahrstrangkopfes about a rotational axis of the pivot connection.
  • the detachable connection of the Anfahrstrangkopfes with the G fauxstrangkopf by at least one connecting element advantageously allows a connection even thin casting strands with the Anfahrstrangkopf that can be separated without cutting the G fauxstrangs of the Anfahrstrang and therefore no subsequent removal of a remaining strand of the G fauxstrang Sharings from Anfahrstrang requires.
  • the pulling up of the starter train also allows easy return of the starter train to the mold, for example with a Anfahrstrangwagen, for which no intermediate storage of the Anfahrstrangs on a Anfahrstrangablage is required and allows a "top feeding" the mold with the Anfahrstrang at the next casting.
  • the invention further provides that the releasable pivot joint between a connecting element and the Anfahrstrangkopf is formed by a propeller shaft bearing and in the propeller shaft bearing and extending along the axis of rotation propeller shaft, wherein the propeller shaft bearing is formed by the first portion of the connecting element and the propeller shaft part of Anfahrstrangkopfes is.
  • Characterized a detachable by the pivoting movement of the Anfahrstrangkopfes when pulling up the Anfahrstrangs connection of the Anfahrstrangkopfes is realized in a structurally simple manner with the G fauxstrangkopf.
  • An embodiment of the invention provides that the Anfahrstrangkopf for each connecting element has a recess for receiving the first portion of the connecting element. As a result, no additional space is consumed by a connecting element with respect to a fixed connection of the Anfahrstrangkopfes with the cast strand head.
  • a further embodiment of the invention provides that at least one connecting element has a hook-like articulated shaft bearing with a concave support surface for a propeller shaft and the Anfahrstrangkopf has at least one propeller shaft with a corresponding to the support surface convex contact surface.
  • the contact surface is located on the support surface when the connecting element is connected to the Anfahrstrangkopf, and is separated by the pivoting movement of the Anfahrstrangkopfes of the support surface.
  • At least one connecting element has a U-shaped articulated shaft bearing, from which a propeller shaft associated with the propeller shaft can be pulled out by pulling up the Anfahrstrangkopfes.
  • a propeller shaft associated with the propeller shaft can be pulled out by pulling up the Anfahrstrangkopfes.
  • an opening formed by the U-shaped propeller shaft bearing for its associated PTO shaft narrows towards the open end of the U and the PTO shaft has different dimensions in directions perpendicular to the axis of rotation, so that they only after the pivoting movement of the Anfahrstrangkopfes from the Cardan shaft bearing is pulled out.
  • a further embodiment of the invention provides that the second portion of at least one connecting element is T-shaped, wherein the bar of the T forms an end of the connecting element.
  • a further embodiment of the invention provides that the hoisting device comprises a winch. This advantageously allows a simple and space-saving design of the pulling-up device.
  • a further embodiment of the invention provides a dummy bar carriage on which the dummy bar can be transported from the pull-up device to the mold. This allows a return of the Anfahrstrangs to the mold for casting another cast strand.
  • At least one connecting element is connected to the starting line by a swivel connection before a continuous casting start and the starting line is positioned such that the starting line head closes the mold exit of the mold and the starting line is guided in the line guide.
  • the second section of the at least one connecting element is poured into the cast strand head of the casting strand.
  • the casting strand and the starter strand connected to the casting strand head are transported through the strand guide and the starter strand is pulled up during transport of the casting strand by the strand guide with the hoisting device at its second approach strand end so that the connection of the approach strand head with the at least one Detached connecting element and the Anfahrstrangkopf is separated from the at least one connecting element.
  • the method allows the connection and automatic separation of the dummy bar even with thin casting strands with the advantages already mentioned above.
  • a further embodiment of the method provides that the Anfahrstrang is pulled up by the puller after the second Anfahrstrangende the Anfahrstrangs has passed the strand guide. This allows the Anfahrstrang be separated immediately after the strand guide of the casting strand, and the Anfahrstrang can be transported back to the mold during the casting process, so that can be started immediately with the casting of another G fauxstrang after the cast strand has left the strand guide.
  • a further embodiment of the method provides that a pull-up speed, with which the dummy bar is pulled up, with a transport speed with which the cast strand is transported through the strand guide, is synchronized. This advantageously prevents the dummy bar from being pulled up too fast or too slowly.
  • a further embodiment of the method provides that the Anfahrstrang is applied after pulling up on a Anfahrstrangwagen and transported with the Anfahrstrangwagen in a transport direction to the mold.
