SATURATION DYNAMICS OF ALUMINUM ALLOYS WITH HYDROGEN

Abstract

This work presents research results on the dynamics of the saturation of aluminum and its alloys with hydrogen in a flow chart for preparing melts in the manufacture of flat-shaped ingots at UC RUSAL. It is demonstrated that one of the main sources of the saturation of an aluminum melt with hydrogen is its interaction with atmospheric moisture during open metal pouring in the course of its transportation from an electrolyzer to a mixer. According to the results of the conducted works, new technical solutions have been proposed whose introduction will ensure, in the long term, a considerable decrease in hydrogen content in aluminum ingots and low-alloyed aluminum alloys.
