Melting Facilities



Melting is the most important process to determine the quality of special metals
and divided into Primary melting, Refining, Casting process.
The primary melting facilities are Induction Melting(IM), Vacuum Induction Melting(VIM), and Plasma Arc Cold Hearth Melting (PACHM).
As refining equipment, we have Argon Oxygen Decarburization (AOD), Vacuum Arc Remelting (VAR)
Up-Hill Casting as casting process 2 ton ,5 ton,6 ton,10 ton,12 ton ingots

Primary melting.
A melting furnace in vacuum using electromagnetic induction.

A furnace that dissolves metals in vacuum and minimizes the loss of alloying elements by blocking pollutants from surrounding environment and removing gases and oxygen contained in metals.
It is used for melting of high purity metals and special alloys.


VAR

Vacuum Arc Remelting


VAR-01

4TonФ540x2700mm

Secondary melting vacuum arc refining furnace.
It is a facility to produce highly purified ingots from ingot or briquette in Primary Melting by removing impurities such as non-metallic inclusions and harmful gas through dissolving work which generates arc in vacuum

It is mainly used in the manufacture of Super alloys, Titanium and Titanium alloys and Super Clean Steel containing elements that are highly reactive with high melting point metals

Special Ti


PACHM

Plasma Arc Cold Hearth Melting


PACHM-01

3TorchØ150x700mm

PACHM-02

3TorchØ350x2500mm

PACHM has high melting efficiency and no impurity contamination by using high heat source of arc plasma.
It controlls high pressure to reduce oxidation pollution as much as possible, High quality ingots can be manufactured by dissolving titanium and titanium alloy scraps.

Stainless Steel


IM

Induction Melting


IM-01

15Ton

IM-02

1Ton

Primary melting.
Electric furnace using electromagnetic induction from the atmosphere.
It is an electric furnace that uses high frequency induction to maximize energy efficiency and dissolves by electromagnetic stirring action.
Since the heat generated from the heating body itself, melting efficiency is high
It is useful for dissolving special metals because of uniform heating and easy output control


AOD

Argon Oxygen Decarburization


AOD-01

13Ton

Secondary melting.
In AOD process, the molten metal is formed by IM and transferred to vessel for AOD.
It is refined (decarburization, desulfurization) process by blowing argon and oxygen mixture gas from bottom of furnance

Used for manufacturing stainless steel or special steel
