Abstract (en)
1. Method for the feederless production of thick-walled container-type castings (1) of spheroidal graphite cast iron, characterised in that the entire mould (3, 6) is of nonyieldable construction comprising a mould core (6) and an outer mould (3), that the castings (1) are cooled both at their inner and at their outer surface, the cooling at the inner surface being effected by cooling of the mould core (6) by coolant, and that the ingates (2) are so dimensioned that the cast iron solidifies in them before the eutectic solidification of the casting (1) sets in.
