Abstract
A melt guide is provided for enclosing a bottom of an electroslag refining crucible containing a melt of electroslag refined metal. A base plate is sized to have a perimeter to engage the crucible bottom for attachment thereto. The base plate includes an upper surface for defining with the crucible a reservoir for receiving the melt, and a lower surface spaced therebelow. A central drain extends through the base plate for draining by gravity the melt from the reservoir. A plurality of circumferentially spaced apart slots extend radially outwardly from the drain toward the base plate perimeter and extend vertically through the base plate. Induction heating coils are mounted below the base plate lower surface for heating the melt through the slots. The base plate may take various forms including a flat plate, with or without a cooperating and removable insert.
