Definitions

  • the invention relates to a method for introducing a starting strand head of a starting strand into the continuous mold of a horizontal continuous casting installation and a horizontal continuous casting installation for carrying out the method.
  • the introduction of the starting strand into the mold is problematic work, u. for several reasons.
  • the mold which is detachably mounted on the distributor vessel, occupies different positions relative to the stationary strand guide, so that the start-up strand inserted into the mold via the stationary strand guide does not exactly align with the mold cavity. It is necessary to slightly raise or lower the start-up line, in particular the start-up line head, in order to avoid a collision of the start-up line head with the mold side walls. Since the mold is attached to the distributor vessel, the thread attached to the start-up strand head can no longer be checked after the start-up strand head has been threaded into the mold. Damage to this seal can no longer be ascertained, and there is a risk that a strand breakthrough will occur at the start of the casting if the head bumps against a side wall edge when the start-up strand head is threaded into the mold.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to provide a method of the type described above or a system for carrying out the method, which enable easy and safe threading of the starting strand head into the mold, with damage to the starting strand head gasket and of the mold side walls can be reliably avoided and the seal of the starting strand head inserted into the mold can be checked.
  • This object is achieved in that the mold is removed from the continuous caster and placed vertically, whereupon the starting strand head separated from the starting strand is threaded into the mold and fixed in position with respect to the mold, that further the mold together with the starting strand head fixed to it installed in the continuous caster, in particular fastened to a distributor vessel, and that the starting strand head is then coupled to the starting strand lying in the strand guide, whereupon the fixing of the starting strand head is released.
  • the aftercooler is advantageously removed together with the mold for the purpose of introducing the start-up strand head.
  • the starting strand head is expediently fixed to the aftercooler by means of a bolt.
  • the start-up line head is coupled to the start-up line by means of a conical connecting bolt passing through these two parts.
  • a horizontal continuous caster for carrying out the method according to the invention with a distributor vessel, a continuous mold which is detachably mounted on its pouring opening and a subsequent cooling device having cooling plates, and with a starting line with a starting line head having a seal is characterized in that the starting line head has a greater longitudinal extent than the after-cooling device , wherein one end protrudes into the mold cavity and the other end can be coupled outside of the after-cooling device with the start-up line and wherein a fixing device is provided for the start-up line head inserted into the mold.
  • Fig. 1 shows a horizontal continuous caster in section in a schematic representation.
  • Fig. 2 illustrates a section along the line II-II of Fig. In an enlarged scale.
  • a distributor vessel 1 can be moved along rails 2 together with a continuous mold 4 fastened to it at the pouring opening 3 transversely to the longitudinal direction 5 of the strand guideway 6, so that the mold 4 together with the distributor vessel 1 is easily exchangeable.
  • a sealing body 7 and a slide 8 are provided between the mold 4 and the distributor vessel 1.
  • the mold 4 itself has a water-cooled part which forms the actual mold cavity 9, to which aftercoolers 10 having cooling plates 11 are connected, the cooling plates of which can be adjusted against the strand surface by means of pressure medium cylinders 12.
  • rollers 13 are provided, which are not driven and serve to roughly center the strand or a starting strand 14. With 15 the roles of strand guidance are designated.
  • the start-up line 14 consists of a start-up rod 16 and a start-up line head 17 which is detachably fastened to this start-up rod and which is provided with a seal 18 at its front end which projects into the mold.
  • the threading position of the Starting strand head 17 to the mold cavity 9 can be accomplished by lifting or lowering the starting strand head (manually or by means of a crane), which is a difficult job in which collisions of the starting strand head with the edges 19 of the mold side walls 20 cannot be avoided.
  • the start-up strand head 17 is detachably fastened to the start-up strand 16, the separation point — when the start-up strand head 17 is threaded into the mold — lies outside the aftercooler 10, that is to say between the aftercooler 10 and the strand guide 6.
  • the start-up strand head has a length that is greater than the longitudinal extent of the aftercooler 10, so that it projects outward through the aftercooler.
  • the start-up strand head 17 has a device for fixing to the mold 4 or to the aftercoolers 10.
  • this device is designed as a hole 21 provided in the start-up strand head, through which a bolt 22 can be inserted, which also passes through plates 23 lying on the side of the start-up strand head and carrying the rollers 13.
  • This bolt 22 has a locking plate 24, which comes out of engagement with a clamp 25 arranged on one of the plates 23 at half a rotation of the bolt.
  • a conical bore 28 is provided on overlapping extensions 26, 27 of these parts, into which a conical connecting bolt 29 can be inserted.
  • a conical connecting bolt 29 By inserting this connecting bolt 29, the start strand head 17 and the start strand 16 are aligned with each other.
  • a screw bolt 30 passing through the conical connecting bolt 29 serves to fix the conical connecting bolt 29.
  • the plates 11 of the aftercooler 10, as illustrated in FIG. 1 are fixed in a retracted position which is lifted off the strand.
  • the head is fixed on the mold-aftercooler 4, 10 by inserting the bolt 22.
  • the mold 4 is installed together with the start-up strand head 17 fixed to it in the continuous casting installation, i. H. mounted on the distributor vessel 1, whereupon the start-up line 16 is coupled to the start-up line head 17 by inserting the conical connecting bolt 29.
  • casting i.e. H. the pulling of the starting strand head 17 from the mold 4 can be started.
  • the invention is not limited to the exemplary embodiment shown, but can be modified in various ways within the scope of the claims.
  • the device for fixing the starting strand head to the mold can also be a clamping device; for example, it is possible to hold the start-up strand head in the mold by clamping between the plates 11 of the aftercooler 10.
