Step1.
EAF
The process turns solid scrap metal and ferroalloys into molten metal using electric potential energy and chemical energy.
×
Step2.
LF
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.

Step3.
VD/VOD
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.
×
Step4.
VSD
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
×
Step5.
I.C
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
×
Step6.
C.C
This process continuously casts metal by passing refined molten steel through a certain form of mold.
