Abstract

A breaker core for use in a casting process includes a disk-shaped breaker core (10) having breaker core body and a through-opening (11) for liquid metal. A ring-shaped frame (12) made from a heat-resistant material is secured to the breaker core (10) and has a netlike webbing (15) tensioned therein. The netlike webbing (15) is made from a fire-proof material and spans the through-opening (11) of the breaker core (10) on an underside of a feeder. The frame (17) is secured with an outer sidewall (17) to the body of the disk-shaped breaker core (10). A plane of the netlike webbing (15) tensioned in the frame (12) is secured with a stepped offset to an upper end of the sidewall (17) facing the feeder, so that the netlike webbing (15) is placed in an area of an underside of the breaker core (10) facing the casting model.
