Abstract
A casting flow running system (11) for supplying liquid metal to a mold cavity formed in a casting mold includes a plurality of pipe sections (13) that are connected to one another; at least one ingate pipe (13) for connecting the casting flow runner system (11) with an ingate of a casting model forming the mold cavity; and a frame (15) made of a heat-resistant material disposed on the ingate pipe (13). The frame has a net-like webbing (18) made of a fireproof material tensioned therein and is attached to the ingate pipe (13) such that the netlike webbing (18) at least partially spans a cross section of the ingate pipe (13) and is positioned in a region proximate to a surface of a casting piece formed by filling the mold cavity.
