Abstract
Inventia se refera la un corp permeabil la gaze, fiind alcatuit dintr-un material poros utilizat la insuflarea gazelor în vederea tratarii metalelor în stare lichida. Corpul respectiv este alcatuit din mai multe elemente asamblate la care miezul estealcatuit din mai elemente asamblate la care miezul este dintr-un material cu o anumita porozitate, iar fetele acestor miezuri poroase sunt în contact cu niste placi metalice. Placile metalice pot avea suprafata neteda sau ondulata pentru a crea nist e canale pentru circulatia gazului utilizat la tratarea metalului lichid.
