Innovative Vacuum Solutions for Vacuum Induction Melting and Vacuum Arc Remelting by Leybold
Modern high-quality metal and alloy production requires precise composition control and material purity. Leybold, a global leader in vacuum technology, offers reliable and efficient solutions for Vacuum Induction Melting (VIM) and Vacuum Arc Remelting (VAR), ensuring superior metallurgical product quality.
Key Processes in Special Metallurgy
1. Vacuum Induction Melting (VIM)
Used for producing stainless steels, superalloys, magnetic materials, and battery alloys. VIM enables:
Removal of gases (hydrogen, oxygen, nitrogen) and impurities from molten metal
Achieving precise chemical composition
Minimizing metal oxidation
Key vacuum system requirements:
✔ Resistance to metal dust and oxides (pyrophoric risks)
✔ Operation at high gas inlet temperatures
✔ Maintaining deep vacuum (down to 10⁻⁴ mbar)
2. Vacuum Arc Remelting (VAR)
Improves metal structure and purity, enhancing fatigue resistance and homogeneity. VAR is critical for aerospace and medical industries.
System challenges:
✔ Removal of aggressive gases and residual moisture
✔ Protection against metal dust
✔ Sustaining high vacuum (down to 10⁻⁴ mbar)
