Applications

Vacuum levitation melting furnace is a new furnace applying the method of electromagnetic induction vacuum levitation melting with water-cooled crucible. It is to place the melted metal or non-metallic solids in the high-frequency or intermediate frequency alternating electric field formed by the induction coil under vacuum conditions, and use the water-cooled metal crucible as the "energy collector" of the magnetic field, so that the energy magnetic field energy is concentrated in the volume space of the crucible, and then a strong eddy current is formed near the surface of the target melt materials.

On the one hand, Joule heat is released to the target melt material; on the other hand, Lorentz force field is formed to suspend (or semi suspend) and stir the target melt material. Due to the effect of magnetic levitation, the target melt material is separated from the inner wall of the crucible, so the heat dissipation behavior between the target melt material and the crucible wall changes from conduction heat dissipation to radiation heat dissipation, which leads to a reduction of heat dissipation rate. The target melt material can reach a very high temperature (1700 ℃ - 2000 ℃), which is suitable for smelting high melting point metals or their alloys.

FAQ

How Does A Vacuum Induction Melting Furnace Work?

A vacuum induction melting furnace works by utilizing electromagnetic induction under vacuum or protective atmosphere conditions to melt metals and alloys that combine easily or have close affinity with oxygen, nitrogen, and hydrogen. The furnace contains a refractory-lined crucible enclosed by an induction coil that generates an eddy current of heat in the material being processed. The furnace's vacuum system totally eradicates gases from the molten metals, and the cooling system contributes to the controlled melting temperature. The furnace is highly reliable, gives high productivity, and produces metals with very close compositional tolerances.

What Is Vacuum Arc Melting Process?

Vacuum arc melting (VAR) is a secondary melting process used to produce metal ingots with high chemical and mechanical homogeneity for critical applications in industries like aerospace, energy, and nuclear. The process involves refining liquid metal under vacuum and controlling its solidification rate. It is used for the purification of reactive titanium or zirconium alloys, without any contact with casting refractories, as well as for improving inclusion cleanliness in steels and superalloys. The remelted cylindrical ingots can weigh several tons, and VAR has revolutionized the specialty metallurgical techniques industry.

What Are The Advantages Of Vacuum Induction Melting?

The advantages of vacuum induction melting (VIM) include the elimination of gases, superior process control, close control of chemical analysis, slag-free melting, and melt protection. VIM is currently the most energy-efficient, fastest, low-consumption, and environmentally friendly induction heating technology for heating metal materials. The technology offers exceptional and reproducible control of reactive element-containing compositions and eliminates the need for a protective slag cover, decreasing the potential for accidental contamination or inclusions in the ingot. The process takes place in a vacuum environment, making it beneficial to remove gas impurities inside the metal, resulting in a more pure metal alloy material.

What Is VAR Vacuum Arc Remelting (VAR)Furnace?

VAR or Vacuum Arc Remelting is a process used to refine and improve the cleanliness of ingots made from standard air-melted, vacuum induction melted, or ESR remelted alloys. It is used for steels, superalloys, titanium, zirconium, and their alloys in industries such as aerospace, power generation, defense, medical, and nuclear. VAR is a continuous remelting process of a consumable electrode under vacuum, with DC power used to strike an arc between the electrode and a copper mold. The process removes dissolved gases, reduces undesired trace elements, improves oxide cleanliness, and achieves directional solidification of the ingot from bottom to top.

How Does Vacuum Help In Induction Melting Furnace?

Vacuum conditions are critical in induction melting furnaces as they help to eliminate gases from the molten metals, preventing quick oxidation. The absence of gases during the melting process ensures the creation of very close compositional tolerances, resulting in consistent metals. The vacuum also provides a protective atmosphere for metals that combine easily or have a close affinity with oxygen, nitrogen and hydrogen. Vacuum induction melting furnaces use electromagnetic induction to melt metals and alloys in a refractory lined crucible enclosed by an induction coil, creating eddy currents that make the melting process possible.

How Does Vacuum Arc Melting Furnace Work?

A vacuum arc melting furnace works by melting materials under a vacuum or low-pressure atmosphere using electric arcs. The furnace uses two electrodes, one of which is the material to be melted. The electrodes are brought close together and an electric arc is struck between them, causing the material to melt. The furnace is then evacuated to remove any impurities and the molten material is cast into a desired shape. This process is used for the production of high-purity metals, alloys, and intermetallics used in industries such as aerospace, electronics, and biomedical engineering.

What Is Vacuum Induction Melting Furnace?

A vacuum induction melting furnace is a metallurgical furnace that uses an alternating electromagnetic field to melt and form various materials under vacuum or protective atmosphere.

Vacuum induction melting furnaces are also used to improve the hot workability and mechanical properties of nickel, cobalt, and iron-based superalloys, as well as to melt stainless steel, heat-resistant steel, ultra-high strength steel, and various other materials to ensure their quality and performance.

What Are The Applications Of Vacuum Arc Melting Furnaces?

Vacuum arc melting furnaces are commonly used in the production of high-performance materials, such as superalloys, special steels, and reactive metals. These materials often require high-purity and controlled composition, which can be achieved through vacuum arc melting. The process is particularly suited for the production of critical components in aerospace, automotive, and energy industries, where high strength, corrosion resistance, and temperature stability are vital. Vacuum arc melting is also used in research and development settings to produce small quantities of specialized alloys for testing and characterization purposes.

What Are The Advantages Of Using Vacuum Arc Melting Furnaces?

Vacuum arc melting furnaces offer several advantages. Firstly, the high vacuum environment prevents oxidation and contamination, resulting in high-purity melted metals. This is especially important for producing materials with stringent quality requirements. Secondly, the electric arc generates intense heat, allowing for rapid and efficient melting of the metal. The process can be precisely controlled to achieve specific melting parameters, such as temperature, pressure, and cooling rate, facilitating the production of alloys with desired properties. Vacuum arc melting furnaces also offer flexibility in terms of the size and shape of the melted metal, as the consumable electrode can be easily replaced or modified. Additionally, the process allows for the selective removal of impurities, such as gases and non-metallic inclusions, further enhancing the purity and quality of the final melted metal.

What Safety Precautions Should Be Followed When Using A Vacuum Arc Melting Furnace?

When using a vacuum arc melting furnace, several safety precautions should be followed to ensure safe operation. Firstly, the furnace should be operated by trained personnel who are familiar with the equipment, its operation, and safety protocols. Adequate personal protective equipment, such as heat-resistant gloves, safety goggles, and fire-resistant clothing, should be worn when handling hot materials or operating the furnace. The vacuum system should be regularly inspected and maintained to ensure proper functionality and prevent safety risks. It is important to follow the manufacturer's guidelines and instructions for safe operation and maintenance of the vacuum arc melting furnace. Additionally, proper handling and disposal of consumable electrodes and melted materials should be carried out according to established safety guidelines and regulations. Regular inspections and maintenance of the furnace, including electrical systems, cooling systems, and gas handling components, should be performed to ensure safe and reliable operation.
