METHOD FOR THE DIRECTIONAL SOLIDIFICATION OF MOLTEN METAL AND CASTING DEVICE FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a casting device which inside a heating chamber (6) has a casting mould (5) which can be displaced from the heating chamber to a bath of cooled molten metal (10) situated below said heating chamber. As heat insulation between the heating chamber (6) and the bath of cooled molten metal (10) the invention provides for a heat insulating layer (13) floating on said bath of cooled molten metal (10) through which the casting mould (5) dips into the cooled molten metal (10). To prevent the formation of clumps within the heat insulating layer (13) the invention provides for a rake or stirrer (19) which is moved by a shaking device (17) and agitates or mixes the heat insulating layer.
