ABSTRACT:
The sum of the areas of the sections of the operational ingates 30 of the mold 4 is, at least at the time of casting, greater than the area of the section of the vertical casting chamber 28, or at least approximately equal to it. This makes it possible to slow the molten metal as it flows into the ingates, and thus to obtain a non-turbulent filling of the impressions or cavities 29.
