Definitions

  • a basket-like metal reinforcement inserted into the refractory material has expansion joints to the refractory material, so that the walls of the immersion bulb are not destroyed by the high temperature and the extreme reactions.
  • the fiber reinforcement of the refractory material is to be produced from austenitic stainless steel sections which are uniformly mixed into the mass.
  • a flange 9, which is embedded in the refractory mass 6, at the end of the filling tube 5 on the diving bulb side serves to fasten the diving bulb 1 to the filling tube 5.
  • 6 expansion joints 13 are provided between the metal reinforcement 12 md of the refractory mass.
  • the refractory mass 6 is given increased stability in that a fiber reinforcement 14, which consists of austenitic stainless steel sections, is uniformly mixed into the mass 6.
  • the filling tube 5 is sealed by a sealing plug 15 to seal the reaction chamber 7 during the treatment.
