Document Type and Number:
Japanese Patent JP2002303490
Kind Code:
A
Abstract:
To obtain a graphite crucible furnace for training scouring utilizing arc of a welder in which molten having a high melting point can be produced by preventing a conductor for supplying a current to the graphite crucible furnace from melting to interrupt current supply when a material having a high melting point, e.g. copper, is melted.
The conductor is prevented from being heated over its melting point by extending a part of the graphite crucible furnace and forming a connecting hand with the conductor at the extended part.
