Abstract
During the simultaneous casting and directional solidification of several castings in pre-heated casting moulds (11), these standing around a central cavity (H) on a ring-shaped cooling plate (5) after pouring off are continuously removed from a heating chamber (14) by a vertical movement relative to the heating chamber in accordance with the solidification temperature and the castings are cooled by heat radiation to below the solidus temperature. In order to increase the production rate and the product quality, the casting moulds (11) are moved over a firm heat sink (9) during the directional solidification by continuous relative movement of the cooling plate (5), said heat sink thereby penetrating into the cavity (H).
