Abstract

Es wird ein Gießverfahren unter Verwendung eines Gießkerns aus mineralischen Schaumkugeln beschrieben. Diese sind zu einer Matrix zusammengeklebt, wobei die Spalte zwischen den Kugeln Infiltrationskanäle für die Schmelze bilden.
Der Gießvorgang gliedert sich in eine Andockphase, eine Infiltrationsphase und eine abschließende Druckphase. In der Infiltrationsphase dringt die Schmelze zumindest in den peripheren Bereich des Gießkerns ein und erstarrt dort. Dadurch entsteht eine Makrotragstruktur, die aus der Statik als Gewölbewirkung bekannt ist und den Abbau von Materialspannung im Werkstoff bei Angriff eines von außen wirkenden Lastkollektives auf den Gusskörper begünstigt.
