Abstract:
A feed system for conveying a molten metal that is to make a casting, the system including a feed channel made of ceramic material that is configured to enable the molten metal to flow by gravity inside the feed channel, the feed channel having a first portion extending in a first direction, and at least one second portion extending in a second direction different from the first direction, the second portion being arranged downstream from the first portion and being connected to the first portion by a junction. The system further includes a damping channel having a first end opening out into the junction and a second end that is closed, the damping channel extending the first portion of the feed channel.
