  • Patent number: 9630243
    Abstract: A continuously operating casting and rolling system with a strip tension control includes a casting unit having a melt-containing feed vessel with a horizontal casting channel and a discharge region in the form of a casting nozzle, and a primary cooling zone with two guide rolls and a circulating cooled casting strip and at least one downstream rolling unit having at least two drivable rollers. In order to minimize the tension on the cast strip, the casting unit and the subsequent rolling unit are mechanically decoupled, wherein for the decoupling at least one driver unit having at least two drivable rollers for driving the strip is arranged between the casting belt and the rolling unit.

  • Patent number: 8408279
    Abstract: The invention relates to a casting nozzle for a horizontal strip casting system, in particular for casting steel strip, wherein the nozzle is designed as a narrow rectangular hollow block having a bottom, top and two side walls and made of refractory material, the outflow region being located only slightly above a cooled continuous belt receiving the outflowing melt. Viewed in the flow direction, it is provided that the clear cross-section of the hollow block in the outflow region reduces uniformly in the direction toward the outflow and the end face of the bottom of the hollow block is designed with respect to the surface of the continuous belt such that the melt contacts the continuous belt perpendicularly.

  • Patent number: 8302663
    Abstract: The invention relates to a casting nozzle for a horizontal strip casting system, especially for casting steel strip. The casting nozzle is connected to a feed channel and is designed as a rectangular refractory hollow block, the outlet region of which being only slightly above the cooled continuous belt which accommodates the outflowing melt. The hollow block is subdivided at least once in the direction of casting and a narrow sealing element is arranged on the partition side of the segments, the width of the remaining gaps in the partition area being selected as to close when the casting nozzle is operated.
