METHOD OF PRODUCTION OF METAL INGOT HAVING OPENING CORRESPONDING INGOT AND CASTING DEVICE Russian patent published in 2014 - IPC B22D7/04 

FIELD: textiles, paper.

SUBSTANCE: invention relates to foundry. The method comprises positioning the form (1) inside the chamber (5) of vacuum moulding, pressure reduction in the chamber (5) to below 0.5 mm Hg., location in the upper part of the mould cavity (3A) of the means (11A, 11') of receiving and distribution of liquid metal, feeding the liquid metal in the chamber (5) of vacuum moulding and filling it with liquid metal. In the upper part of the chamber (5) the means is (9) located for feeding liquid metal. The means (11A, 11') of receiving and distribution of liquid metal is made with the ability to receive the liquid metal fed into the chamber (5) of vacuum moulding, and the ability to distribute the liquid metal in the mould cavity (3A). Feeding the liquid metal into the chamber (5) of vacuum moulding is performed to form the first jet (50) of liquid metal under vacuum for casting liquid metal on the means (11A, 11') of receiving and distribution of the second jet (52) of liquid metal under vacuum, fed to the moulding cavity (3A).

EFFECT: obtaining of forged ingots a with low hydrogen content is provided.

16 cl, 4 dwg
