Definitions
- a generic Gasspüieinriehtung as it is known from DE 197 55 199 Cl, has a refractory, ceramic Gasspüi stone and arranged at the bottom of Gasspüisteins gas distribution chamber, from which gas permeable areas through the gas purging plug to gas outlet was ti en end of Gasspüisteins extend.
- the gas flushing device comprises a gas supply line provided with a
- the chamber is at least partially permeable to the ceramic body gas.
- the plate 50 has a so-called non-directional porosity, that is, a chwam m arti ge internal structure, so that gas flowing via the line 30 can flow through the open porosity of the plate 50.
- the plate 50 is simultaneously raised (Fi gur 2) until it reaches its maximum upper position when the plate 50 abuts against the Anschl ag 20 a.
