Definitions

  • the invention relates to annealing containers for the heat treatment of filling material arranged therein with a bottom and side walls made of carbon reinforced with carbon fibers.
  • the object of the invention is to provide annealing containers which avoid the disadvantages of the known boxes.
  • This object is achieved by annealing containers for the heat treatment of contents arranged therein with bottom and side walls, which are characterized in that the container made of carbon fiber reinforced carbon with a porosity of 2-30 vol.% And a carbon fiber content of 30-70 vol. % consists.
  • the container which is preferably open at the top, can also have a lid made of CFC material.
  • the reinforcing fibers are endless stretched carbon fibers.
  • Fiber fabrics, woven fabrics or nonwovens made from endless stretched carbon fibers are impregnated with polymer resins, pitches, bitumen and so-called prepregs are produced, from which open, preferably rectangular or square containers are formed by deep drawing or pressing.
  • Flat lids or lids with a rim in a dimensioning corresponding to the container size can be produced in the same way.
  • the blanks of the containers produced in this way are subjected to a heat treatment in order to convert the materials used to impregnate the fiber fabrics, woven or non-woven fabrics into carbon.
  • Carbonization is usually carried out at a temperature of 200 to 1000 ° C.
  • the porous structure of the material is then compacted by liquid impregnation with phenolic resins, furan resins, polyphenylenes, pitch or mixtures thereof. This is followed by a heat treatment at 200 ° C to 2900 ° C to graphitize the wall and floor material or the lid of the container.
  • the material structure can also be compressed by chemical deposition of carbon in the pores under vacuum.
  • the proportion of reinforcing carbon fibers in the graphitized material is 30-70% by volume, preferably 45-60% by volume.
  • the compacted material has a low porosity or a low pore content of 2-30, preferably 5-15 vol.%.
  • the surfaces of the container and the lid are metallized by deposition of metals under vacuum, for example with tantalum, niobium, molybdenum, copper / Nickel alloys.
  • metal oxide layers such as zirconium oxide, aluminum oxide, can also be deposited for surface protection.
  • Good surface protection can also be achieved by siliconizing and / or converting it to SiC or glazing with silicon dioxide and / or boron compounds of the surface of the CFC material can be achieved. Protection is also possible by applying ceramic layers.
  • Particularly suitable materials are TiN, BN and TiC.
  • CFC material is already sufficiently inert to the filling material and is heat-stable when used, in which the filling material to be annealed or sintered is subjected to a heat treatment of 500 ° C to 2500 ° C in a reducing or inert atmosphere in push-through ovens or deck ovens.
  • the containers according to the invention can be produced in different sizes up to about 100 x 100 cm with side wall heights of 1-50 cm.
  • the size depends on the size of the furnaces in which the annealing container for the heat treatment of the filling material is to be made later.
  • a standard size is 30 x 40 x 10 cm.
  • Preferred wall thicknesses are 1-8 mm.
  • the attached figure shows an annealing container 1 according to the invention in longitudinal section with bottom 2 and side walls 3 made of carbon material reinforced with carbon fibers.
