  FERROUS   Refractory   GAS DEFUSER  
 
GAS DEFUSER
  DESCRIPTION

This is a general purpose plug consisting of a hydraulically-pressed and high temperature refractory shape whose granulometry has been designed to optimise gas flow with resistance to metal penetration. Available in permeable magnesite or permeable high alumina, this diffuser is suitable for a wide variety of applications across a spectrum of metals and alloys, from aluminium to stainless steels and can be operated in ladles from only a few kilos to many tonnes. A permeable alumina ceramic has been developed for use in the induction furnace. A permeable diffuser can also be used for aluminium. Its chemistry is modified to impart non-wetting characteristics and so it can be used in multiples within melting and holding furnaces.

 

Benefits of gas diffusers:

Reduction in scrap rate
Improve quality of castings
Reduction in pin-holing
Removal of inclusions
Reduction in gas content
Temperature homogenization
Distribution of alloying agents and de-oxidants
