Energy efficiency model of scrap aluminum regeneration during alloying process

The energy efficiency model of scrap aluminum regeneration during alloying process was estab-lished. The effects of processing parameters in condition of adjusting different kinds of alloying elements on alloying energy efficiency were analyzed. Combined with the gas consumption model, the minimum a-mount of gas volume supplied was presented in different alloying process. The results show that when the same content of an element is adjusted, the higher alloying energy efficiency is realized in feeding than that in dilution, and the higher the content of target alloying element in master alloys used in feeding is, the higher alloying energy efficiency is. The highest alloying energy efficiency can be observed with adding Si than any other elements. By optimizing way of gas supplied, when alloying process is completed, melt temperature just reaches the required temperature, where the highest alloying energy efficiency can be realized.
