Definitions

  • the invention relates to a method for securing a starter strand in a strand guide of a continuous casting plant and a continuous casting plant with a starter strand.
  • the invention relates to a continuous casting with a mold and a subsequent strand in the conveying direction strand guide, and with a Anfahrstrang that closes the mold at the start of casting exit and can be held and moved in the strand guide of engagable and driven strand guide rollers, the strand guide rollers a transport path for form the Anfahrstrang.
  • the mold Before the start of a casting process, the mold is closed on the output side with the head of a starter strand.
  • the Anfahrstrang is either promoted from below in an upward movement along the strand guide mostly with engagable and driven strand guide rollers to the mold and held in this starting position of the strand guide rollers or starting from the Casting platform conveyed from above through the mold and then held in the strand guide in turn by the engagable and drivable strand guide rollers in the starting position.
  • An operator error or failure in one - the adjusable and drivable strand guide rollers - means of electrical, hydraulic, pneumatic or communication, can lead to a sudden onset, constantly accelerating downward movement of the heavy Anfahrstrangs in the strand guide, with this movement, the so-called Crash, typically over a long distance (eg over several strand guide segments and / or traction roller scaffolding).
  • This risk is particularly high in vertical casters, as this type of plant has a vertical strand guide.
  • the crash of the starter train can lead to personal injury as well as damage to individual plant components. For safety reasons, operating personnel are therefore not allowed to stay in hazardous areas during this phase of operation.
  • Another object of the invention is that the Anfahrstrang can be secured both during threading, while holding in the starting position and after the start of pouring. Furthermore, the securing of the Anfahrstrangs should be independent of the weight starter strand and in particular work well even with very heavy Anfahrstrfiten.
  • the Anfahrstrang is transported during the threading of drivable strand guide rollers in the strand guide in the direction of mold and then held before the casting start in a mold on the output side closing starting position of engagable strand guide rollers.
  • the Anfahrstrang when threading and holding at least one in Strang adoptcardi downstream locking device secured, ie the movement of the Anfahrstrangs in the strand conveying direction is blocked by at least one locking device.
  • the Anfahrstrang is secured both during threading, while holding and during Ausfiln against an uncontrolled crash.
  • a plurality of locking devices are distributed in the strand guide (e.g., comprising one or more strand guide segments or traction roller frames) which are sequentially secured as the dummy strand is threaded and sequentially released after casting commencement.
  • sequential unlocking of the locking devices proceeds undisturbed by securing the starter strand.
  • the securing of the starter strand by a plurality of distributed in the strand guide, locking is largely independent of the length of the Anfahrstrangs, whereby the backup of very short Anfahrstrnature is possible.
  • the plurality of locking devices further reduces the distance in the event of a crash until the starting line is intercepted in the strand guide, which increases safety.
  • an arresting device automatically secures the startup line in the event of a failure of a device of electrical, hydraulic, pneumatic or communication. This increases the safety when threading, holding and unthreading the dummy bar.
  • the automatic securing of the starter strand without external, i. from outside the locking device, energy. This further increases the safety during threading, holding and unthreading of the dummy bar
  • At least one locking device for the Anfahrstrang is arranged in the strand guide, which lies from a lying outside the transport path release position in a transport path the Anfahrstrangs locking catch position is formed displaced back and forth.
  • Anfahrstrang is designed as a link chain or rigid, or has a straight or curved shape.
  • a locking device on a front side of a Strand guide segment or a drive roller frame or between two, adjacent in the strand conveying direction, strand guide rollers, preferably driven strand guide rollers arranged.
  • the force for securing or intercepting the Anfahrstrangs is introduced via the locking device in an advantageous manner in the strand guide segment or in the drive roller frame.
  • a locking device can also be arranged in a separate support structure. By means of this embodiment, it is possible to assemble or disassemble the locking device independently of strand guide segments or driving roller stands.
  • a simple embodiment is to form a locking device as a displaceable or pivotable bolt, wherein the bolt is designed to be displaceable by a Betuschistsvorrichung. It is particularly advantageous to use the bolt and the actuating device in an assembly, e.g. As a cassette, form so that this module can be easily and quickly assembled or disassembled.
  • a further embodiment is to form a locking device as a displaceable, inclined plate or a displaceable, obliquely located bolt, wherein the weight of the locking device defines the basic position of the locking device and the locking device is displaceable via an actuating device in the release position. This ensures that the locking device automatically secures the Anfahrstrang in case of failure of the actuator.
  • a further embodiment consists in that the actuating device comprises a, for example pneumatic or hydraulic, pressure accumulator, wherein the pressure accumulator formed by means of a pressure medium cylinder Actuator defines the basic position of the locking device. This ensures that the locking device automatically secures the Anfahrstrang in case of failure of the actuator.
  • a further embodiment consists in that the actuating device comprises a spring, wherein the spring force defines the basic position of the locking device. This ensures that the locking device automatically secures the Anfahrstrang in case of failure of the actuator.
  • the Anfahrstrang a transverse to the transport path recess, preferably a slot or a U-shaped recess, and on the Anfahrstrang on, engaging in the recess, displaceable bolt, is secured.
  • a locking device is designed as a displaceable or pivotable plate, wherein the plate is designed to be displaceable by an actuating device.
  • Fig. 1 is a vertical caster in a longitudinal section with the essential components of the invention shown schematically. It comprises a mold 1, in which a cast strand of molten steel is formed during the casting process, and an adjoining vertical strand guide 2, in which the cast strand is continuously cooled, guided and supported.
  • the strand guide is formed by a series of strand guide segments, of which four strand guide segments 3a, 3b, 3c, 3d are shown as representative.

  • phase 2 the Anfahrstrang 4 has already passed the strand guide segment 3d and the locking device 8c has been closed, whereby the Anfahrstrang is secured against falling. Subsequently, the Anfahrstrang is in turn moved by means of drivable and / or engageable strand guide rollers 7c, 7d and secured by means of the locking device 8b in phase 3 and 8a in phase 4.
  • phase 4 of the Anfahrstrang has reached the starting position for the casting start, whereby the head of the Anfahrstrangs 4 closes the mold 1 on the output side.
  • the Anfahrstrang can also be threaded from above, ie from the casting platform, through the mold in the strand guide (eng., Top feeding ) .
  • the Anfahrstrang is usually introduced by a movable on the casting platform Anfahrstrangwagen or a crane through the mold and lowered to a locked locking device. Afterwards the crane is suspended from the starting line, so that any incorrect operation is excluded. Furthermore, the drivable and / or engageable strand guide rollers are turned on and the Anfahrstrang accurately positioned in the strand guide and the locking device again locked. Also in this embodiment, it is advantageous, depending on the length of the Anfahrstrangs at least one locking device to keep closed during threading and so to secure the Anfahrstrang.
