PHYSICAL MODEL OF THE DIFFUSION INTERACTION OF ARGON BUBBLES WITH AN ALUMINUM MELT

A physical model of diffusion interaction of argon bubbles with an aluminum melt in the process of hydrogen outgassing from it by blowing an inert gas through the porous bottom of a refi ning vessel is presented. The dependence of the effi ciency ε of the diffusion interaction of argon bubbles with the aluminum melt on the dimensionless complex criterion B has been investigated. Three characteristic regions of the dependence ε(B) have been distinguished. Analysis of this dependence made it possible to develop energy- and resource saving regimes of the technology related to the economics of argon.
