Abstract
A method for shielding a molten metal cooling bath used in directional casting of superalloys from a high temperature furnace environment. A plurality of floating ceramic baffles are used, floated on the top of such cooling bath so as to substantially cover the surface thereof. Each baffle member comprises a hollow ceramic member and ceramic seal means sintered to such hollow member so as to form a hermetically sealed chamber within the hollow member. The baffles are displaced during the directional casting process when a mold containing the cast article is lowered into the cooling bath. A ceramic baffle of this construction is also disclosed.
