MANUFACTURING METHOD OF CASTING MOULDS WITH APPLICATION OF SELF-CURING MIXTURES WITH FOLLOWING COMPACTION BY FILLING COMPOUND Russian patent published in 2009 - IPC B22C9/00 

Abstract RU 2374030 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to foundry field. Method includes installation on moulding plate of moulding, revetment by self-curing mixture of casting mould, compaction of filling mixtures. On moulding plate it is installed flange of height not less than 2/3 of height of mould and it is located by perimetre around mould at a distance providing cascading of self-curing mixture. Filling of fixtures by filling mixture is implemented under pressure on self-curing facing sand up to its solidification. On surface of impress of mould in those places where it is formed durable superficial crust, it is applied antipenetration wash.

EFFECT: simplification of method of ingots receiving.
