Vacuum Induction Melting Furnace
- Therelek’s Vacuum Induction Melting furnace (VIM) is used in secondary refining or metallurgy, to refine alloys in fluid state and adjust chemical composition and temperature.
- This increases the required quality demands of the material.
- Therelek’s vacuum induction melting furnaces are generally used in secondary refining of many complex alloys in aerospace engineering.
- The material gets homogeneous and clean after refining and removal of dissolved and bonded impurities.
- The vacuum levels is set to be in the range of 10-1 to 10-4 mbar during the refining phase.
- Our furnaces comes with vacuum / controlled atmosphere and precise control for melting.
- The melting process is comparatively easier in VIM, attributing the independent control of time, pressure, temperature and transport through melt stirring.
- In the process of vacuum induction melting, we have flexibility to control the alloy composition by sampling & addition of required alloys.
- Small batch sizes
- Quick change in program of steels and alloys
- Easy operation
- Reduction in Oxidation losses
- Compositional tolerance achieved
- Precise Temperature control
- Low environmental pollution
- Used in aircraft engine components for casting
- Used in making super alloys
