Definitions

  • the invention relates to a casting-rolling plant for producing metal strips according to the preamble of claim 1, and a method for operating such a casting-rolling plant.

These cast-rolling plants are designed for low annual production of between 0.5 and 0.8 million tonnes per year. In adaptation to this, the components of these plants with respect to vertical height (up to 3 m, without the mold) and metallurgical length (less than 4.5 m) are designed accordingly, adapted for these compact systems also adapted low casting speeds (up to 4.8 m / min). As a result, advantageously low investment costs are realized for such systems.

  • Advantageous developments of the invention are defined in the dependent claims.
  • a casting-rolling plant is used for producing metal strips, wherein a metal strip passes through this casting-rolling plant in a conveying direction.
  • the casting / rolling plant comprises a casting machine with a mold with a vertical outlet for producing a casting strand, a strand downstream of the mold in the conveying direction strand guide for deflecting the casting strand from the vertical to the horizontal, a downstream of the strand guide in the conveying direction connection system, the at least one separation device , in particular a pair of scissors, as well as a furnace for heating the casting strand, and a rolling mill downstream of the connection system in the conveying direction for rolling the casting strand to form a metal strip.
  • the strand guide at least one support roller pair is provided, which is connected to a drive.
  • the invention is based on the essential finding that it is possible, with the aid of at least one support roller pair, which is provided or connected in the strand guide with a drive, to achieve an increase in production in a compact casting-rolling plant with little effort, for example an annual production of 0.8 - 1, 4 million tons per year.
  • the driven support roller pair improves the conveyance of the casting strand through the curved strand guide, so that at the end of the strand guide, where the casting strand emerges in the horizontal direction, lower withdrawal forces are required to further transport the casting strand in the conveying direction to the rolling mill. Accordingly, e.g. realize greater casting speeds, with which the cast strand emerges from the casting machine.

Such a larger minimum radius of curvature ensures that crack-sensitive grades can also be cast with the cast-rolling plant according to the invention. In the same way, with an increased minimum radius of curvature of the strand guide, casting strands having larger thicknesses can also be cast or processed, which likewise leads to a greater annual production.
  • the abovementioned ranges or enlargements of the metallurgical length and of the minimum radius of curvature of the strand guide advantageously lead to increased production being possible for the cast-rolling plant according to the invention, in particular by raising the casting speed to values of up to 6 mm / min.

  • the subdivision of the strand guide into a plurality of roller segments also leads to the advantage that these roller segments can be changed separately from each other. Thus it is possible, e.g. to selectively remove or replace only one roll segment from the strand guide for repair or maintenance purposes.
