Definitions

  • the invention relates to a side plate of a continuous casting mold for producing a casting strand of metal materials.
  • the continuous casting mold disclosed therein consists essentially of copper side plates.
  • Each of the side plates has 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.
  • insert parts also called patches, are used to reduce the cross section of the cooling channel in each case to a desired residual cross-section.
  • the fittings are either made of temperature-resistant plastic or a metal.
  • the invention is therefore the object of developing the filler for the cooling channels of the side plate in a known side plate of a continuous casting mold to the effect that they are not only thermally stable, but at the same time chemically neutral to the coolant in the cooling channel, are elastic and easy to work mechanically.
  • these two selected and claimed materials are characterized on the one hand by a 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 that the coolant can assume when passing through the cooling channels.
  • these claimed materials also show a chemical neutrality or durability against the coolant, which is not only pure water, but water with z. T. aggressive chemical additives. In this respect, it is advantageous for these materials that these materials are not attacked by their consistency or surface in the chemical additives. Also, these materials are electrochemically neutral, d. H. In particular, no ion exchange with the cooling water takes place. In addition, these materials remain elastic even in the chemically enriched coolant; d. H. advantageously, they do not embrittle.
  • the filler has at least one stabilizer insert in the form of a profile bar.
  • the dimensional stability of the filler is further increased.
  • the use of such a stabilizer insert is particularly recommended when the filler from Polyurethane is made. When using polyacetal, the use of such a stabilizer insert is usually unnecessary.
  • the patches can be made either 100% or only part of one of said plastics. In the latter case it is then composite material.
  • the claimed side plate is, for example, a wide 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 a single figure attached showing a side plate, in particular a wide side plate of a continuous casting mold.
  • the figure shows a side plate, in particular a wide side plate 100 of a continuous casting mold.
  • the continuous casting mold is used for casting liquid metal materials into a cast strand.
  • the side plate 100 limits on one side the casting space of such a mold.
  • the casting chamber of the continuous casting mold facing side of the side plate is also referred to as hot side 110 while the side facing away from the hot side of the mold is referred to as cold side 120.
  • a plurality of cooling channels 130 can be seen for passing a coolant for cooling the side plate 100.
  • the cooling channels 130 are limited in their cross section by filling pieces 140 inserted.
  • the patches also define the cross section of the respective Cooling channel over the height.
  • the filler pieces according to the invention are at least partially made of the plastics polyurethane or polyacetal.
  • stabilizer inserts in the form of profile bars 150 can be embedded in the filling pieces 140.
  • These profile bars can in principle have any cross-section; however, typically they 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.
