Definitions

  • the invention relates to a method for producing a cylinder of an internal combustion engine and an apparatus for performing this method.
  • the invention has for its object to find a method and an apparatus for manufacturing a cylinder that avoid the disadvantage of long cooling time and can precisely represent the connection between steel and cast iron with little effort.
  • the single figure shows a schematic sectional illustration of a molding box 1 and therein an outer mold 2 made for vertical casting from mineral molding material.
  • An associated core 3 is fastened centrally in the interior of the outer mold 2.
  • the space between the core 3 and the outer mold 2, which is a casting mold 4, is dimensioned such that a steel ring 5 to be provided on its inner surface with a gray cast iron running layer and an induction coil 6 surrounding the steel ring 5 can be arranged concentrically with the core 3 to be introduced later.
  • the induction coil 6 is fixed in the outer mold 2 with refractory concrete in such a way that a cavity 7 remains between the inner surface of the steel ring 5 and the outer surface of the core 3, which serves as a lower section of the mold 4 for receiving the iron forming the gray cast iron layer.
  • a cavity 8 lying above the steel ring 5 forms the upper portion of the casting mold 4, the remaining cylindrical sleeve outer shape.
  • the mold 4 is filled with protective gas, for example with argon.
  • tubular electrical feed lines 9 of the induction coil 6 as well as the induction coil 6, which is also made from tube cross sections, run in the molded material of the outer mold 2.
  • the surface section of the core 3 opposite the steel ring 5 is provided with fireclay plates 10 for protection against the heat radiation.
  • the steel ring 5 is heated in the mold 4 by means of the induction coil 6 to white heat.
  • the casting mold 4 is filled with liquid gray cast iron via pouring channels 11, the latter entering into a fusion welded connection with the incandescent steel ring 5.
  • the composite blank After the composite blank has cooled, it is removed from the casting mold 4, destroying it, and fed to further processing.
  • the preheating of the steel ring 5 can also be carried out in another way, for example by introducing a flame gas behind the steel ring 5 or according to the principle of resistance heating.
  • the steel ring 5 can be provided on the inner surface with a protective layer of nickel, tin or other suitable materials before it is introduced into the casting mold 4 in order to ensure additional protection against oxidation.
