	Electroslag remelting is complementary to the induction furnace because it specifically supports refining reactions (~~specifically~~ removing sulfur, non-metallic oxides, free oxygen) ~~which occur in the slag~~.

Conventionally, a previously melted and cast ingot rod from another type of furnace is fed into the top of an electroslag remelter. However Centroteh suggests that, alternatively, a fixed carbon electrode can feed the heating current and chopped scrap can be fed directly into the slag pool. Very interesting!!
