Abstract

Dispersion of lead during smelting wrought aluminum alloys of the Al–Cu–Mg system with Pb additives and coarsening of lead-bearing phase particles during casting have a significant effect on ingot structure formation. The possibility of controlling these processes during preparation of lead-bearing aluminum alloys in a transport ladle due to melt modification with surface-active tin and electromagnetic mixing during input of briquetted master alloy containing wt.%: 50 Al, 45 Pb, 5 Cu is investigated. Optimum parameters for mixing melt providing effective dispersion of lead and its uniform distribution within the volume of melt are established.
