Abstract
Dispozitivul, conform inventiei cuprinde un agitator rotativ, mijloacele de actionare ale acesteia si un buson permeabil la gaz, solidar cu fundul recipientului ce consine baia de metal topit, prin care se injecteaza gazul de rafinare. în scopul optimizarii conditiilor de dispersare ale gazului inert si de agitare a baii, dispozitivul este prevazut cu un agitator rotativ care se sprijina la capatul inferior, pe busonul de injectie a gazului de rafinare. în scopul optimizarii conditiilor de dispersare ale gazului inert si de agitare a baii, dispozitivul este prevazut cu un agitator rotativ care se sprijina la capatul inferior, pe busonul de injectie a gazului de rafinare, fixat în pozitie coaxiala cu agitatorul si care agitator, sub actiunea presiunii agitator sub actiunea presiunii gazului emis de buson si sustinut de un palier fluid, poate sa se roteasca liber în jurul axei sale sub actiunea unui cuplu exterior, permitînd sa iasa prin spatiul ce-l separa de buson bule de gaz inert dispersate regulat, atît agitatorul cît si busonul fiind imersate în baia de metal topit se confectioneaza din materiale hecorodabile de aluminiu topit si de preferinta din grafit.
