Abstract
A cold hearth for an electroslag refining crucible includes a floor above which a melt pools. The floor includes a drain for draining the melt by gravity. A plug is deployed inside the drain to block discharge of the melt therethrough, and an actuator is attached to the plug for withdrawing the plug from the drain to permit drainage of the melt upon startup.
