ABSTRACT:
A start-up system for an electroslag remelting furnace having a bottom pouring device connected to a mold in which at least one electrode is remelted to form an ingot. The bottom pouring device is positioned to receive molten slag and pass it through the lower part of the furnace mold until it rises in the mold and contacts prepositioned current conducting elements in order to complete the electrical power circuit of the furnace. The system includes a slag transfer apparatus which is either located or is shiftable to a location adjacent the bottom pouring device for controlling the transfer of molten slag into the bottom pouring device. The method of operation of the system components is also disclosed.
