METHOD OF MOULD GRAVITY DIE CASTING OF LARGE-SIZE CASTS FROM MAGNESIUM ALLOYS

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to foundry field. Before pouring internal surface of die casting die is heated up to temperature 150-200C 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. ^ 1 tbl, 1 ex
