Definitions

  • gas purging blocks are known, which are assembled in the refractory lining of the treatment vessels.
  • an outer end is the supply of a treatment gas or a gas / solid mixture, which then flows through gas-permeable portions of the gas purging plug, then at an inner end (the "hot end") flow out of the gas purging plug and to flow into the melt.
  • the secondary dishwasher 20 is designed as follows:
  • channels 26 instead of the discrete, linearly extending channels 26 (example according to FIG. 1 ) are the channels 26 in the example according to FIG. 2 "Reverse U-shaped" designed, that is, the free legs extend from the gas distribution chamber 24 and are connected to each other at a short distance in front of the sheet 29.
  • the metal jacket 28 adjoins the metal sheet 29, extends around the gas-permeable part 25 and then passes into the metal wall of the gas distribution chamber 24.
