Steelmaking-Forging Process

Steelmaking Process

Material Loading ELectric Furnace LF(Ladle Furnace) VD(Vacuum Degassing) Continuous Casting


The steelmaking process is a crucial process that determines the quality of specialty steel products and consists of the melting, refining, and casting process.

Melting facilities include 100-ton/60-ton electric arc furnaces and VIM(Vacuum Induction Melting) for ultra-clean manufacturing.

For the refining process, secondary refining processes such as LF, VD, VOD and AOD are available and ultra-clean, high-functioning parts materials are manufactured by the ESR process which is a special refining technique.

The casting process is divided into continuous casting and ingot casting, allowing the production of semi-finished items such as billets, blooms, and ingots.

Billets are manufactured in curved continuous caster and the largest-section blooms in the world are manufactured for the production of high-quality, ultra-clean steel.

We are also able to manufacture ingots weighing from 4 tons up to 150 tons, depending on specific customer demand.

Forging Process

Heating Furnace Forging


In the forging process, steel ingots are heated and forged into various shapes such as marine shafts, engine parts, plant shells and discs, bars, and plates.

After forging, forgings are heat treated to meet the mechanical requirements. Visual inspection, UT(Ultrasonic Testing), and witness inspection by third parties are performed for quality assurance of the products.
