METHOD OF PRODUCING A CAST COMPOSITE MATERIAL Russian patent published in 2017 - IPC C22C1/10 C22C49/06 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy and can be used for production of composite cast materials for parts of vehicles, machines and equipment. Method involves preparation of aluminium charge containing 20 % of aluminium scrap and 80 % of aluminium scrap with addition of liquid hydrocarbon, one loads into furnace 20 % of aluminium scrap, its melting and subsequent loading into liquid aluminium scrap melt with addition of liquid hydrocarbon, and after complete melting of charge one blows the melt with oxygen during 3 hours under slag layer formed on melt mirror, which is removed at the end of the blowing, and produced melt is poured into the mold.

EFFECT: invention ensures production of cast composite material with aluminium matrix reinforced with plate-like inclusions of aluminium oxide, with high mechanical properties.
