Definitions

  • the shaping of the metal strand subsequent to the casting can only influence the profile and flatness of the final product to a limited extent. For this reason, it is advantageous, the cast metal strand already in the casting process, a suitable thickness profile or a suitable Emboss the thick contours and, among other things, avoid a thickness wedge wherever possible.
  • the known fact that the cast strip thickness depends substantially on the heat flow via the casting roll surface and the contact time is utilized for influencing the cast profile in twin-roll belt casting machines. Both factors together determine how thick the tape shell can form at the relevant point. On the variation of these sizes on the casting roll width can thus be influenced to a considerable extent the thickness profile of the cast metal strand.
  • the contour of the casting roll and the setting (position and / or contact pressure) of the casting rolls themselves is influenced by the thermal expansion and thus by the local heat flow.
  • the heat flow across the casting roll surface is determined, on the one hand, by the heat transfer coefficient from the melt to the casting roll and, to an even greater extent, by the heat transfer coefficient from the solidified strand shell to the casting roll. Furthermore, the temperature difference between casting roll and strand shell or molten bath is crucial for the heat flow.
  • the temperature of the casting roll is usually set in the prior art by an internal cooling - possibly supplemented by an external cooling - set.
  • the contact time is determined by the rotational speed of the casting roll, the casting roll geometry and the casting level. For a smooth melt surface, the contact time is to a first approximation constant over the width of the cast strand. Thus, only the heat flow remains as a possible manipulated variable to influence the strand shell thickness and the roll geometry over the strand width.
  • a casting roll method in which a molten metal is poured into a mold region, which is delimited on a first side by a first casting roll rotating about a horizontal first axis of rotation, and a metal strand produced by solidification of the molten metal is removed from the mold region.
  • a gaseous cooling medium is applied to the surface of the first casting roll from above by means of a number of first coolant applying devices.
  • the cooling medium is supplied to the first coolant application devices via first coolant lines.
  • the cooling medium is inert with respect to molten metal and has a standard boiling point below 20 ° C, based on normal atmospheric pressure.
  • an armature of the first casting roller is detected.
  • the altitude is supplied to a control device of the first cooling device.
  • the control device automatically determines a drive state of the first cooling device as a function of the applied iron shaft and a corresponding target property and controls the first cooling device accordingly.
  • a casting roll method in which a molten metal is poured into a mold region delimited on at least one side by a first casting roll rotating about a horizontal first axis of rotation. From the mold area, a metal strand generated by solidification of the molten metal is removed. Via a first cooling device, water is applied to the surface of the first casting roll by means of a number of first coolant applying devices. By means of at least one sensor, an armature of the first casting roller is detected. The oil level is supplied to a control device of the cooling device.

  • the first coolant lines are covered with a thermal insulation. This also achieves thermal protection from the ambient temperature. This protection is all the more important, the lower the boiling point of the cooling medium and the longer it takes the transport of the cooling medium from a reservoir to the firstdeffenetzbring Anlagenen.
  • gas separators are arranged in the first coolant lines.
