In modern industry, the demand for high-performance materials is growing, especially in critical sectors such as aerospace, medical, and energy. Vacuum Induction Melting (VIM) technology has become an indispensable cornerstone for producing high-quality alloys.
VIM’s Core Technology and Advantages
The core of VIM lies in its unique melting method. It uses a magnetic field generated by an induction coil to heat and melt metals in a vacuum environment. This process not only precisely controls the melting temperature and alloy composition but also effectively removes impurities such as gases and oxides from the metal, resulting in high-purity alloys.
Precise Control of Induction Heating
- The induction coil generates a changing magnetic field, inducing eddy currents in the metal, which generate heat.
- Temperature is precisely controlled by adjusting the current frequency and intensity.
Purity Assurance in a Vacuum Environment
- Effectively removes active gases such as oxygen, nitrogen, and hydrogen, preventing oxidation and gas inclusions.
- Removes volatile impurities, improving alloy purity.
Diverse Crucible Selection
- Suitable crucible materials, such as magnesium oxide, aluminum oxide, and graphite, are selected based on the type of molten metal and temperature.
Precise Control of Alloy Composition
- Alloying elements are added during the melting process to ensure uniform composition.
- Combined with online composition analysis, real-time monitoring of composition changes.
