Low pressure bottom casting device for casting liquid metals

摘要

The post-filling device has a pressure-tight melt container (14) and a filling pipe (18) arranged in the oven with a lid (20). The melt container is coupled pressure-tight to the filling pipe via a run-off (16). The oven is connected to the melt container via a pneumatic pressure compensating line (22). Apparatus for low pressure casting of metal melts comprises a casting station (6) arranged on a conveyor track (1), a gas pressure oven (7) containing the melt (8) with a pouring spout (10) joined to the sand molds (2), and a device to post-fill the oven with melt.
