Definitions

  • the invention relates to a guide device for inserting and withdrawing a cold strand into or out of a continuous casting mold or strand guide of a continuous casting installation, the cold strand being guided by one or more rails running parallel to the casting direction.
  • the bottom of a continuous casting mold must be closed by means of a cold strand before the start of casting.
  • Liquid steel is then poured into the mold, which is closed at the bottom, and after a solid strand start head has been formed, which is positively connected to the cold strand, the withdrawal of the cold strand and thus the pulling out of the casting strand is started.
  • the cold strand is separated from the warm strand and, in most known machines, is pushed onto an auxiliary rail by deflection.
  • the device described has the disadvantage that it can only be used for sheet-fed systems and, on the other hand, only allows the cold strand to be pivoted out of the strand guide at a specific point along the rail.
  • a device according to the invention avoids this disadvantage. It is suitable for use in a casting plant with a straight mold for billets or blooms in a vertical system with or without bending the strand and has a design according to which the cold strand is guided by a carriage that runs on rails that run parallel to the strand guide , moves, and is characterized in that the rails have an area that can be pivoted about an axis.
  • the device according to the invention has the advantage that it can be used on all types of continuous casting plants with a straight or curved mold with or without bending the strand, and that, depending on the choice, the cold strand can be cleanly separated from the warm strand at different strand heights.
  • a straight mold 1 is shown at the time of the start of pouring, wherein it is closed at the bottom by means of the cold strand 2.
  • liquid steel is then poured into the mold 1 from a pan (not shown) via a distributor vessel.
  • support and guide rollers 3 are shown, which are arranged immediately below the mold, where the solidification has not yet progressed, at a relatively small distance from one another and further and further below each other.
  • the cold strand 2 is guided by means of an arm 6 from a carriage 5 which can move by means of rollers 7 along a straight rail which extends parallel to the strand guide 4 and which consists of two parts 8 and 9, which in their working position aligned with one another, the upper part 8 being fixed in its position, and the lower part 9 being able to be pivoted by means of a hydraulic cylinder 11 about a pivot point 10 located below the separation point between the two parts 8 and 9.
  • This pivot point and the rear point of attack of the cylinder 11 are firmly connected to the supporting structure of the casting system.
  • the carriage 5 can be driven by means of a remote-controlled electric motor, not shown.
  • the rail parts 8 and 9 are in the aligned position and the cold strand 2 is introduced into the mold 1 by raising the carriage 5.
  • the carriage is moved downwards along the rail at the casting speed, with the hot strand being pulled along by the cold strand.
  • the decoupling of the cold strand can take place as soon as it is no longer guided between the closely spaced rollers 3, but is already in the region of the rollers 3 'which are at a distance from one another which is greater than the length of the cold strand , which is about 1 m.
  • the cold strand 2 which is connected to the carriage 5 via the arm 6, is guided over the rollers 3.
  • the arm 6 is guided from the carriage 5 between two rollers at 90 o to each other.
  • the four rollers 3 are rotatably mounted on fixed axes 21 by means of roller bearings 12, the axes 21 being seated on bearings 13 fixed to the building.
