Vacuum Melting Furnace

Vacuum Melting Furnace Description:

Vacuum melting furnaces combine medium-frequency induction heating with a vacuum environment to provide a controlled and efficient method for melting metals and alloys. It produces high-purity and high-quality materials.
Medium-frequency induction furnaces use alternating current frequencies typically between 1 kHz and 10 kHz. This frequency range is high enough to generate sufficient eddy currents for efficient heating, but low enough to minimize energy losses due to the skin effect. Vacuum induction melting technology offers significant advantages over traditional melting methods, including the ability to prevent oxidation and contamination, ensuring the production of high-quality materials.

Application:

Vacuum induction melting furnaces are used in a wide variety of research and production areas, including:

Casting of aerospace components
Complex valves for extreme conditions
Refining of high-purity metals and alloys
Production of electrodes for remelting
Nickel and special steel production
Precision alloy manufacturing
Active metal processing
High-temperature alloy development
Magnet material manufacturing

Vacuum Melting Furnace Features:

• High Purity and Quality
  Vacuum Induction Melting (VIM) provides superior purity and quality of melted material. The vacuum environment prevents contamination by oxygen, nitrogen and other atmospheric gases. This results in a cleaner, more homogeneous melt, free of harmful inclusions and impurities that could affect mechanical properties.
• Precise Temperature Control
  Vacuum Induction Melting (VIM) allows for precise temperature control during the melting process. The induction heating system ensures consistent and repeatable results, which is critical for producing materials with specific properties and compositions.
• Multiple Material Compatibility
  Vacuum Induction Melting (VIM) furnaces can process a wide range of materials, including metals, alloys and even ceramics. This versatility makes them suitable for a wide range of applications, from aerospace components to high-temperature alloys and magnet materials.
• Energy Efficiency
  The induction heating system in VIM furnaces is highly energy efficient. This not only reduces operating costs, but also minimizes environmental impact.
• Other Benefits
  Vacuum Environment: Prevents oxidation and degassing.
  High-Temperature Capability: Suitable for melting high melting point alloys.
  Electromagnetic Stirring: Minimizes element segregation during melting.
  Removal of volatile trace elements: By controlling the vacuum environment, harmful elements such as antimony and bismuth can be removed.
