Fire retardant continuous casting process

A method for continuously casting lithium-containing alloys by a direct chill process includes cooling the alloy (6) to form a continuous ingot (8) having a solid shell (12), further cooling the ingot (8) by direct chill with an organic coolant (18), and inhibiting fire by adding non-aqueous fire re...

Zusammenfassung:	A method for continuously casting lithium-containing alloys by a direct chill process includes cooling the alloy (6) to form a continuous ingot (8) having a solid shell (12), further cooling the ingot (8) by direct chill with an organic coolant (18), and inhibiting fire by adding non-aqueous fire retardant liquid to the coolant. In one embodiment, the fire retardant liquid is miscible in the coolant (18). In a separate embodiment, the fire retardant liquid provides a substantially immiscible barrier layer (21) on the coolant.
