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 refining vessel is presented. The dependence of the efficiency 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. [ABSTRACT FROM AUTHOR]
