Definitions

  • DE-OS 1 433 402 a pressure pan with filler and pouring spout is described in which for the production of cast iron with nodular graphite the opening of the filler neck and the opening of the pouring spout of the pressure pan during the time the pressure gas is applied to the surface of the magnesium to be mixed liquid cast iron are sealed pressure-tight by means of end caps.
  • the pressure-tight sealability of the furnace chamber cover or the sealing cover is achieved by means of a sealing strip.
  • the cover of the furnace chamber has a sealing strip on its sealing surfaces which bear against the furnace chamber and the closure cover on its sealing surfaces which bear against the walls of the common pouring and pouring siphon, which engages in sealing joints provided on the boundary walls of the furnace chamber or on the siphon walls.
  • the sealing strip preferably has a T-shaped cross-sectional profile.
  • the furnace chamber has at least one pressure relief valve arranged on the cover, which is electrically controlled by the closing device of the cover and / or the closure cover, the device for keeping liquid metal melts warm can be operated extremely safely. It can e.g. B. be provided that the lid is blocked until the pressure in the furnace chamber is relaxed to normal atmosphere (see also sub-claims 9 and 10).
  • the sealing surfaces 4b on the front area of the furnace chamber 3 has a T-shaped sealing strip 7 which engages in a sealing joint 8.
  • the frontal areas of the furnace chamber 3 and the cover 4 and the structural design of the sealing strips 7 and the sealing joints 8 is chosen so that after the furnace chamber 3 is closed by the cover 4 by means of a refractory mass (e.g. corundum), it is additionally covered can be used to increase the tightness of the furnace chamber.
  • the lid 4 is clamped to the furnace chamber 3 in a pressure-tight manner via a closing device 11 by means of a wedged tie rod 10.
  • the structural design of the seal of the pivotable closure cap 6 of the common pouring and pouring siphon 2 can be designed completely analogously to the pressure-tight seal of the furnace chamber 3. However, for reasons of simplification, this has been omitted in the drawing.
