Abstract
Inventia se refera la un procedeu de obtinere a unui dop refractar superaluminos cu permeabilitate dirijata, pentru barbotarea cu gaze inerte prin fundul oalei de turnare a otelurilor speciale, tratate prin procedee cunoscute cu temperatura maxima de utilizare de 1850 degree C.Produsul refractar obtinut are o structura densa, compacta, în care se practica un anumit numar de canale cu diametrul sub 1 mm. El contine, în principal, un agregat refractar superaluminos, format din fractiuni granulometrice în diverse proportii si silicat de etil.
