Definitions

  • the invention relates to a plug rod arrangement on casting furnaces and other metallurgical vessels according to the preamble of claim 1.
  • a plug rod arrangement is known from US-A-4 219 139.
  • nodular cast iron titanium
  • spheroidal cast iron Similar problems as with spheroidal cast iron also exist with other types of melts.
  • the slag piles or the like on the sealing surfaces between the stopper rod and the pouring hole brick can cause leaks.
  • the invention has for its object to develop a plug rod assembly of the type mentioned, in which compared to the known plug rod assembly greater pouring accuracy and greater security against leakage of the plug rod closure is achieved as a result of slag deposits.
  • the rod protruding into the pouring hole opening as a piston, which can be moved independently of the stopper rod, the pouring hole opening can be cleaned particularly quickly and easily.
  • the sealing surface between the pouring hole brick and the plug rod can be cleaned.
  • This rotary movement of the stopper rod can be carried out after each closure of the vessel or after several closure processes.
  • This turning of the plug rod is in addition to the movement of the piston. In certain cases, e.g. if you want to save time, the piston movement and the plug rod movement can also take place simultaneously.
  • the piston tip can e.g. consist of ceramic material, which can be provided with steel reinforcement or other reinforcement.
  • the stopper rod is made of ceramic material.
  • 5 denotes a pouring furnace or another metallurgical vessel which is provided with a pouring brick 4.
  • the pouring of melt from the casting furnace 5 is controlled by a stopper rod 2.
  • the stopper rod is provided with a central or substantially central channel in which a piston 3 is arranged so as to be able to move back and forth.
  • the lower part of the piston that is to say the part which reaches the area of the pouring hole brick, preferably consists of ceramic material which can be provided with steel reinforcement or another reinforcement.
  • the piston 3 can be moved back and forth in the longitudinal direction of the stopper rod through the opening of the pouring hole brick 4, any slag present in the pouring hole of the pouring hole brick 4 being removed.
  • the piston 3 in the stopper rod 2 has essentially the same diameter as the opening in the pouring hole brick 4. After each pouring, a pressure can 7 presses the piston 3 through the opening in the pouring hole brick 4 via a rod 7 and thereby removes the slag that has accumulated there .
  • the piston - at least at its lower end - is made of a material with a high melting point, such as ceramic material.
  • the stopper rod can carry out a rotary movement which is brought about, for example, by a pneumatic cylinder 6. This rotary movement can either after each closing or after a number of Closures take place, for example after every tenth closure. The rotary movement can take place independently of the movement of the piston 3 and / or together with it.
  • the embodiment of the invention described with reference to the figure can be varied in many ways within the scope of the claims.
  • the arrangement according to the invention is not only applicable in the casting of spheroidal cast iron, but can also be used in the casting of other melts.
  • the invention can be used not only for pouring furnaces, but for all types of metallurgical vessels with pouring stone.
