METHOD OF MOULD GRAVITY DIE CASTING OF LARGE-SIZE CASTS FROM MAGNESIUM ALLOYS Russian patent published in 2010 - IPC B22D15/00 

Abstract RU 2381867 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to foundry field. Before pouring internal surface of die casting die is heated up to temperature 150-200°C and there are applied two layers of heating paint of different composition and heat conduction with rising bottom-up thickness. Liquid metal is poured into immovable cast iron metal mould through vertical wells without usage of vertically-slotted feeders.

EFFECT: there is achieved reduction of expenditure of energy and improvement of shaped casting.
