Definitions

  • the invention relates to a side plate of a continuous casting mold for producing a casting strand from metal materials.
  • the continuous casting mold disclosed there essentially consists of copper side plates.
  • the side plates each have a hot side facing the casting space of the continuous casting mold and a cold side facing away from the hot side.
  • a cooling channel is milled on the cold side of the side plate.
  • Inserts, also called fillers, are used in the cooling channels in order to reduce the cross section of the cooling channel to a desired remaining cross section.
  • the fittings are either made of temperature-resistant plastic or a metal.
  • the advantage of using plastic instead of metal is that weight can be saved by using plastic, which improves the oscillation dynamics of the mold. Furthermore, the manufacturing costs for plastic fillers are significantly cheaper than for metal fillers.
  • the invention is therefore based on the object, in a known side plate of a continuous casting mold, to further develop the filling pieces for the cooling channels of the side plate in such a way that they are not only thermally stable, but at the same time chemically neutral to the coolant in the cooling channel, elastic and easy to machine.
  • this selected and stressed material is characterized by good thermal dimensional stability. This is important because the fittings define the cross section of the cooling channels and this cross section must also be maintained at higher temperatures, which the coolant can assume when passing through the cooling channels.
  • the claimed material also shows a chemical neutrality or resistance to the coolant, which is not only pure water, but water with z. T. aggressive chemical additives. In this respect, it is advantageous with this material that this chemical additives do not attack its consistency or surface.
  • This material is also electrochemically neutral d. H. in particular, there is no ion exchange with the cooling water. In addition, this material remains elastic even in the chemically enriched coolant; d. H. advantageously not embrittled.
  • this plastic is also neutral with regard to the reaction to magnetic fields and when irradiated with e.g. B. X-ray light for measurement purposes.
  • the filler has at least one stabilizer insert in the form of a profile bar.
  • This stabilizer insert further increases the dimensional stability of the filler.
  • polyacetal the use of such a stabilizer insert is usually unnecessary.
  • the claimed side plate is, for example, a broad side plate of the continuous casting mold.
  • the side plate can be made of copper, for example, regardless of whether it is a narrow side plate or a wide side plate.
  • the description is accompanied by a single figure, which shows a side plate, in particular a broad side plate of a continuous casting mold.
  • the figure shows a side plate, in particular a broad side plate 100 of a continuous casting mold.
  • the continuous casting mold is used to cast liquid metal materials into a casting strand.
  • the side plate 100 delimits the casting space of such a mold on one side.
  • the side of the side plate facing the casting chamber of the continuous casting mold is also referred to as the hot side 110, while the side of the mold facing away from the hot side is referred to as the cold side 120.
  • a plurality of cooling channels 130 can be seen for the passage of a coolant for cooling the side plate 100.
  • the cross section of the cooling channels 130 is limited by fillers 140 used.
  • the filler pieces also define the cross-section of each Cooling channel above its height.
  • the fillers are made according to the invention from polyacetal.
  • profile bars 150 can be embedded in the filler pieces.
  • These profile bars can basically have any cross-section; however, they typically have an annular, polygonal, U-shaped, T-shaped or L-shaped cross section. Alternatively, they can also be designed as a threaded rod.
  • the stabilizer inserts 150 are made of a different material than the rest of the filler, for example they are made of metal or carbon fiber.
