Definitions

  • the invention relates to a system for producing hot-rolled steel strip from a continuously cast starting material, in which the cast strand is wound up into a bundle in a reel station after leaving the continuous casting system and is reeled off into a rolling mill in a further reel station after the bundle has been moved, the reel stations being fed into are arranged in a common oven.
  • Such systems are known. They have the advantage that continuously produced hot-rolled strip from a continuously cast master material is inexpensive because a considerable saving in energy is made possible solely by the fact that the facilities for reheating the slabs, intermediate transport devices and storage spaces required in conventional processes and systems are dispensed with.
  • the cast strand which has already been cast in the form of a strip makes it unnecessary to reduce the cross section with a high amount of deformation and high deformation energy and permits coils to be wound up immediately behind the continuous casting installation. This winding or reeling is necessary because the maximum casting speed at which the cast strand leaves the continuous caster is much lower than the lowest possible rolling speed of conventional roll stands.
  • the object of the present invention is to improve the arrangement of the reel stations within the furnace in such a way that unproblematic winding and unwinding of the cast strip and, if appropriate, intermediate storage is possible and the implementation of the federal government is simplified.
  • the invention proposes that the transport means for the bundles are winding mandrels which are movable on an orbit running horizontally or vertically in one plane.
  • winding mandrels run around in the invention so that tape can also be wound and converted which cannot be wound on mandrelless winding devices.
  • the winding mandrels with the furnace can be rotated about a vertical axis.
  • Another advantageous proposal of the invention provides that the circumferential path of the winding mandrels is self-contained and runs in a vertical plane and the winding mandrels can be moved step by step.
  • more than two winding mandrels can be moved simultaneously in the orbit, which can advantageously be moved on a circular path, but also it is conceivable to provide another self-contained movement path when the orbital plane is perpendicular.
  • the invention advantageously enables the winding mandrel to be driven in each case in the winding and unwinding station.
  • the mandrels are driven independently of one another and the drives which are fixed relative to the winding path of the mandrels are detachably coupled to the mandrels. This is recommended because the winding mandrels have to work with different drive speeds due to the different speeds for reeling and unwinding.
  • the mandrels can, if necessary, be brought into the respective winding position step by step and coupled there to the drives.
  • a further feature of the invention provides that a device for controlled heating of the cast strand to the reel or rolling temperature is arranged in front of and / or behind the furnace. Such devices can of course be omitted if the temperature of the furnace allows rolling without reheating or the temperature of the greeting strand corresponds to the reel temperature.
  • a device for separating the cold beginning of the band is provided according to another feature of the invention.
  • a gas-tight supply line for a furnace heating gas which is stationary with respect to the furnace is provided for heating the furnace.
  • the furnace can be rotated on a turntable or a turntable for rotating the furnace.
  • the winding mandrels are arranged in the inlet-side reel furnace of a Steckel rolling mill.
  • the decoiler station can be used in a known manner for multiple coiling and uncoiling of the strip rolled in reversing stitches, that is, in the manner of a plug-in oven as is known with only one coiler station.
  • the winding mandrels are arranged in a manner known per se before a cross-section shear and / or devices for descaling.
  • the cross-cut shear is required when the cast strand weight is greater than the coil weight of the coil located in the take-up reel station.
  • Descaling equipment is usually required behind the furnace to prevent the scale from rolling into the mill.
  • FIG. 2 is an enlarged view of the furnace according to the invention shown in FIG. 1,
  • FIG. 3 is an illustration of the furnace of FIG. 2 with four mandrels
  • Fig. 4 is a rotatable about a vertical axis furnace with integrated mandrels and
  • FIG. 5 shows a plan view of the furnace according to FIG. 4
  • Fig. 1 the continuous casting system is indicated at 1.
  • the cast strand B passes through a pair of scissors at 2 before it is introduced into the furnace 3 with the aid of the driver 6 and wound up on the mandrel 4.
  • the winding mandrel 4 can be moved on the circular orbit U shown in dashed lines in the direction of the arrow into a position in which the winding mandrel 5 is drawn in FIG. 2.
  • the cast strand B is unwound from the winding mandrel 5 with the aid of the driving apparatus 7 and is fed to the rolling mill 10 through the heating device 6, the cast strand B having previously passed through the descaling device 9.
  • a cooling section is indicated at 11, in which the strip is cooled before it is wound up at 12.
  • FIG. 3 An alternative is shown in FIG. 3, in which four winding mandrels 4, 4a, 5, 5b are arranged movably on the orbit U.
  • the winding mandrels have the same spacing from one another and allow intermediate storage of wound bundles in the stations 4a and 5a.
  • the device for heating the cast strand can also be located between the continuous casting installation 1 and the furnace 3; it can also be a special device only for heating the strip edges.
  • the embodiment of the invention shown in FIG. 4 is particularly favorable because the oven 3 can be kept small. As a result, the amount of heating gas used is small, which is important for a good energy balance.
  • the winding mandrels 4, 5 are arranged in a fixed manner within the furnace 3, while the furnace 3 itself can be rotated about the vertical axis 13.
  • the furnace 3 is mounted on a rotating ring 14 on guide rollers F and is moved by a stationary drive 15, which corresponds to a ring gear 16.
  • a gas supply 17 is provided, which can take place, for example, via a known rotary feedthrough.
  • a clamping device 19 for the band end 20 is provided in the region of the opening of the furnace 3, with which the same is held during the rotation of the furnace 3 by 180 degrees and thus during the transport of the coil into the unwinding position.
  • the fixed end of the bundle which now represents the beginning of the bundle for further processing of the federal government, can be pulled out by means of a driver 21 and can be fed to a separating device (not shown) which separates this beginning of the bundle, which has cooled outside the furnace.
  • the shafts of the mandrels 4, 5 are guided out of the furnace 3 on both sides thereof and provided with couplings 22 for the fixed drives.
  • the couplings can optionally be engaged or disengaged on one or the other side of the mandrels 4, 5, so that the mandrels 4, 5 can be driven easily and at different speeds.
  • the furnace 3 can always be rotated in the same or alternately in one or the other direction by 160 degrees.
