Definitions

  • the invention relates to a method for producing a cooled ring carrier according to the preamble of claim 1.
  • the invention is based on the problem, the known method for the production of a ring carrier with a cooling channel to improve so far, that it is easily executable, and that it is the disadvantages of the state the technology avoids.
  • ring carrier 1 for one on its outside arranged piston ring 2 has on its ring carrier back 3 a recess 4 in the form of a downwardly open recess.
  • the ring carrier 1 in a known manner from a gray cast iron with an 18% nickel content Alloy.
  • the ring carrier 1 is inserted into a casting mold, which is, for example, filled with aluminum.
  • a casting mold which is, for example, filled with aluminum.
  • salt granules at a pressure of 100 to 300 N / mm 2 in the recess 4 pressed so that a salt core 5 forms from the salt granules.
  • the ring carrier 1 and the salt core 5 existing composite preheated to a temperature of 200 ° C to 250 ° C, before the ring carrier-salt core composite in a third step 2 1 ⁇ 2 to 5 Immersed for 1 ⁇ 2 minutes in an Alfinbad, which is called from a ca 730 ° C.
  • Aluminum melt consists. The meaning of this is that in the following Process step for producing an aluminum piston after insertion of the ring carrier 1 in a casting tool and the casting of the piston itself used aluminum well with the gray cast iron alloy from which the ring carrier 1 exists, connects.
  • Fig. 2 shows an enlarged view of a marked in Fig. 1 with A. Area in which the ring carrier 1 with the piston ring 2, on his back. 3 mounted recess 4 and the pressed-in salt core 5 clearly visible are.
