Influence of the technology of aluminum waste melting on the composition and the possibility of using the generated dust

Abstract

It is shown that the amount of flux used in melting significantly influences the composition and volume of dust and gas emissions. Based on the results of the chemical analysis of dust a solution was adopted for the fluxless melting of aluminum waste. In this case, the proportion of chlorine-containing compounds is 1.4% at 75% of aluminum oxides, which makes it possible to use the formed dust to produce a deoxidizing mixture or a refiner slag. On the basis of balance melting, it is shown that with fluxless melting of aluminum waste, a waste-free processing technology is realized, ensuring ecological and economic effects.
