Definitions

  • the invention relates to a process for the production of castings with cast steel pipes, the castings made of cast steel and the steel pipes cast with an overheated cast steel melt and filled with a granular, highly heat-conductive refractory material before casting.
  • the invention has for its object to provide a method of the type mentioned, in which the disadvantages of the known methods are avoided and by means of which, in particular, the cooling tubes made of steel are embedded in the cast body.
  • the granular material used individually or as a mixture of magnesite (sintered magnesite), corundum, sintered alumina, chromite, SiC, Si 3 N 4 is used as the pipe filler.
  • Mixtures of fired magnesite with up to 30% each of an addition of one or more other granular materials as tube filler are preferably used as the granular material. It is also advantageous to use a mixture of technically pure SiC and Si 3 N 4 in any mixing ratio as tube filler.
  • composition of the tube filler should preferably the calcined magnesite ⁇ 75% MgO, preferably ⁇ 90% MgO, the chromite ⁇ 3 0% Cr 2 0 31, preferably ⁇ 40% Cr 2 0 3, the corundum and the sintered alumina ⁇ 90% Al 2 Contain O 3 , preferably ⁇ 95% Al 2 O 3 and the materials obtained in a natural or synthetic way are said to be typical impurities as the remainder eg on Si0 2 , Al 2 O 3 , CaO, M g O, Fe 2 0 3 / Fe0 in the smallest possible amount.
  • the granular tube filler has the most dense spherical packing possible due to its grain size composition, i.e. that a minimal void fraction is present, which would significantly reduce the otherwise high thermal conductivity of the materials used according to the invention.
  • the grain size of the pipe filler is between 0 to 3 mm, preferably between 0 to 1 mm.
  • composition of the cast steel melts to be used in the process can vary depending on the intended use within the limits specified below, since in addition to unalloyed and high-alloy cast steel, for example for heat-resistant and / or scale-resistant castings can be used.
  • the above-mentioned object is achieved in a process for the production of castings with cast-in steel pipes, the castings being made of cast steel and the steel pipes being cast with an overheated cast steel melt, so that the steel pipes to be poured in are provided with pipe segments which lie snugly on the pipe surface or Pipe shells made of steel are provided so that only a minimal air gap remains between the steel pipe surface and steel pipe segments or shells.
  • the steel pipe segments or steel pipe shells only cover 1/3 - 1/2 of the steel pipe surface and are only placed on the upper side of the casting.
  • the wall thickness of the steel pipe segments or steel pipe shells to be placed is expediently 1/2 to 3 times that of the pipes to be cast in.
  • FIG. 1 shows a cast body in section
  • FIG. 2 shows a section on an enlarged scale according to II-II in FIG. 1.
  • a steel tube 2 is inserted, which with a thin surface coating 3 (Fig. 2), for . B. made of Al 2 O 3 .
  • the steel tube is filled with a sintered magnesite 4 with a grain size of 0.5 mm.
  • the cast body 1 surrounding the steel tube 2 has the following chemical composition:
  • the casting temperature is approx. 152 0 - 155 ° C.
  • the steel pipe to be poured corresponds to material St 35.8 / II according to DIN 17 175.
  • Fig. 2 shows in detail the steel pipe 2 to be poured in with its approx. 50-200 ⁇ m thick coating 3, the pipe filler 4 and a steel pipe shell 5 placed thereon, which is provided with bores 6 and bevels on the edges 7.
  • the tubular steel shell 5 comprises approximately 1/3 of the circumference of the tubular steel 2 and, as can be seen from FIG. 1, is located on the upper side of the casting marked "a".
  • the thickness of the steel tube shell 5 corresponds approximately to that of the steel tube to be poured in, namely approximately 8 mm.
