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 in a further coiler station after the bundle has been moved, and the reel stations are fed in are arranged in a common oven.
  • Such systems are known. They have the advantage that continuously produced hot-rolled strip from a continuously cast starting material is inexpensive because a considerable saving in energy is made possible solely by the fact that the facilities necessary for reheating the slabs, intermediate transport devices and storage spaces are not required in conventional processes and systems.
  • 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 degree of deformation effort 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 reeling and unwinding of the cast strip and, if appropriate, intermediate storage is possible and the implementation of the federal government is simplified.
  • winding mandrels circulate in the case of the invention, so that tape can also be wound and converted so that winding cannot be carried out on mandrelless winding devices.
  • the winding mandrels are driven independently of one another and the drives which are fixed relative to the orbit of the winding mandrels are detachably coupled to the winding mandrels. This is recommended because the winding mandrels have to work with different drive speeds due to the different speeds for reeling and unwinding. If necessary, the winding mandrels can be brought into the respective winding position step by step and can be 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 the 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 line corresponds to the reel temperature.
  • cross winding shears and / or devices for descaling be arranged downstream of the winding mandrels in a manner known per se.
  • 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. 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 8, 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 shows an alternative in which four mandrels 4, 4a, 5, 5b are arranged so as to be movable 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 continuous casting installation 1 and furnace 3; it can also be a special device only for heating the strip edges.
