METHOD FOR OBTAINING ALLOY ON BASIS OF ALUMINIUM OF Al-Pb SYSTEM

摘要

FIELD: metallurgy.;SUBSTANCE: magnesium in quantity of not more than 3% is added to aluminium molten in melting pot with addition of beryllium alloy combination; at the same time, molten aluminium is prepared with 10-16 % of lead of aluminium weight. After that, molten aluminium with lead is poured into molten aluminium with manganese, mixed, and poured on granules by molten metal efflux through a hole made at melting pot bottom.;EFFECT: obtaining an alloy having high degree of lead recovery and more uniform distribution of lead inclusions in aluminium.;1 tbl, 3 ex
