The process turns solid scrap metal and ferroalloys into molten metal using electric potential energy and chemical energy.

In this refining process, molten metal produced in an electric furnace is poured into a ladle, electric potential energy is used to increase the temperature, the chemical composition is adjusted by introducing the ferroalloy, and harmful chemical elements are removed through slag refining.

VD(Vacuum Degassing)
The VD process removes harmful gases, such as hydrogen, nitrogen, and oxygen, by exposing molten steel that has gone through the LF process to a vacuum.

VOD(Vacuum Oxygen Decarburization)
The VOD process for refining stainless steel removes carbon compounds from molten steel using oxygen in a vacuum state.

This process removes hydrogen by exposing molten steel flowing into molds to a decompressed vacuum state, and produces an extra-large ingot through top pouring.
Produces up to 700 tons of ingot

This process produces an ingot by bottom-pouring molten steel into a certain form of mold at atmospheric pressure. Produces from 10 to 80 tons of ingot

This process continuously casts metal by passing refined molten steel through a certain form of mold.
