The filling of the mold, however, is in all cases terminated. is formed under the action of a high pressure of the press piston 11; moreover, the gas in the casting mold is removed through its ventilation channels and collected in a measure of 8, but some of it remains closed in the gas collection pocket 18.1

В установке, выполненной таким образом, кристаллизаци  происходит при очень боль шом давлении растворимого газа на свободнуго поверхность расплава в газосборном кармане (по сравнению с давлением, при котором происходит насыщение). Таким образом газ остаетс  в растворенном состо нии.In a plant made in this way, crystallization occurs at a very high pressure of soluble gas on the free surface of the melt in the gas collection pocket (compared to the pressure at which saturation occurs). Thus, the gas remains in a dissolved state.
