Detail & Parts
Features
The Vacuum Induction Melting Furnace is a sophisticated piece of equipment designed to melt metals under high vacuum conditions, offering numerous benefits for research and production in various industries. This furnace is particularly beneficial for melting valuable active metals and alloys, preventing reactions with non-metallic inclusions, and removing harmful dissolved gases and pollutants from the molten metals. Here are the main features of this furnace:
- Air-Tight Water-Cooled Steel Jacket: The furnace is equipped with an air-tight, water-cooled steel jacket that can withstand the required vacuum for processing, ensuring a stable and controlled environment for melting.
- Induction Heating System: Utilizing medium frequency induction heating, the furnace can reach temperatures up to 2000℃, making it suitable for melting a wide range of metals and alloys, including nickel, special steel, and high-temperature alloys.
- Crucible and Refractory Lining: The metal is melted in a crucible housed in a water-cooled induction coil, and the furnace is lined with suitable refractories to enhance durability and performance.
- Vacuum and Inert Gas Casting: The molten metal can be poured or cast under either vacuum or inert gas environments, providing flexibility in processing and ensuring the purity of the final product.

These features collectively ensure high-quality melting and casting of metals, making the Vacuum Induction Melting Furnace an indispensable tool for industries requiring precision and purity in their metalworking processes.
Principle
The vacuum induction melting furnace operates on the principle of medium frequency induction heating, where a high vacuum environment is created to melt metals. The furnace utilizes an induction coil to generate an alternating electromagnetic field, which induces eddy currents within the metal, causing it to heat up and melt. The vacuum environment prevents oxidation and contamination of the molten metal, allowing for the production of high-purity alloys. This process is particularly suitable for melting high-temperature alloys, active metals, and materials requiring precise composition control.
Advantages
Vacuum induction melting furnace is mainly composed of furnace body, support, inductor, furnace tilting mechanism, vacuum system, medium frequency power supply and electrical control system.
- Furnace body: The furnace body and furnace cover have water-cooled interlayer to ensure the furnace surface temperature will not be too high; Side door at the furnace body can be added according to user requirements; Furnace cover is equipped with alloy feeder and observation window, which can add different alloy raw materials during smelting and observe the working conditions in the furnace.
- Inductor: The furnace inductor is coiled into a spiral coil with thick wall copper tubes, and the outer layer of the induction coil is covered with a ceramic coating, which increases the firmness and extends the service life of the coil while ensuring the insulation of the coil.
- Furnace tilting mechanism: manual furnace tilting, electric furnace tilting and hydraulic furnace tilting are available for users to choose. The furnace tilting angle is designed to tilt forward 105 degrees and backward 10 degrees without residual liquid. The furnace tilting speed can be adjusted continuously.
- Vacuum system: consists of mechanical pump, roots pump, diffusion pump or booster diffusion pump, vacuum valve, damping elastic sleeve and vacuum pipeline. The configuration principle of vacuum system is to configure according to the physical and chemical properties and process of smelting materials.
- Medium frequency power supply: IGBT medium frequency power unit, max. Temperature is up to 2000 ℃ .
- Electrical control: Touch screen controller with PLC, vacuum measuring instrument, temperature measuring instrument and operation button, indicator light,and other components. It can realize the operation and control of pneumatic system, vacuum system, furnace cover lifting, furnace tilting, etc.
Safety Advantage
- Effectively control and adjust alloy composition to produce high-performance metal or alloy materials.
- Capable to inhibit the formation of non-metallic oxide inclusions produced in the metal solution and cast high-quality castings.
- The unique electromagnetic stirring feature can effectively avoid element segregation during alloy smelting.
- According to the different melting points of elements, some harmful volatile trace elements, such as antimony, tellurium, selenium, bismuth, etc., can be removed purposely

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
