Abstract
1. СПОСОБ ЛИТЬЯ ПОД НИЗ КИМ ДАВЛЕНИЕМ С ПРОТИВОДАВЛЕНИЕМ , включающий насыщение расплава газом, создание противодавлени в форме, заливку расплава в форму под избыточным давлением и выдержку его под давлением до затвердени , отличающийс тем, что, с целью повышенн качества отливок путем устранени ут жин и трещин на поверхности массивных узлов отливки, после затвердевани расплава вокруг массивного узла , противодавление на поверхности этого узла снижают. 2. Способ по п. 1, отличающийс тем, что расплав насыщают водородом.1. METHOD FOR CASTING UNDER LOW PRESSURE SIMULATED PRESSURE, including saturating the melt with gas, creating a counterpressure in the mold, pouring the melt into the mold under excessive pressure and maintaining it under pressure until hardening, characterized in that, in order to improve the quality of the castings by eliminating the slabs and cracks on the surface of massive casting units, after solidification of the melt around the massive unit, the back pressure on the surface of this unit is reduced. 2. A method according to claim 1, characterized in that the melt is saturated with hydrogen.
