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

What Is A Vacuum Furnace Used For?

A vacuum furnace is used for high-temperature processing of materials in a controlled environment without any contamination. It operates by surrounding the product with a vacuum, which prevents oxidation and heat loss from the product through convection. This furnace is commonly used for heat treatment of steel alloys at temperatures below 1200 °C. High-temperature vacuum furnaces can reach temperatures up to 3000°C and are used for industrial processes such as sintering, brazing, annealing, and heat treatment with high consistency and low contamination. The ability to achieve uniform heating across the entire workpiece is a key benefit of using a high-temperature vacuum furnace.

What Is The Process Of A Vacuum Furnace?

The process of a vacuum furnace involves loading the parts into the chamber and creating a vacuum inside it by utilizing a vacuum pump. The next step is to heat the parts using temperature controls, which can reach between 1,500 and 5,400 degrees Fahrenheit. This process eliminates the possibility of oxidation and contamination, resulting in a higher purity end product. After heating, the parts are cooled and finished before being removed from the vacuum furnace. The furnace consists of various components, including the vacuum system, furnace shell, electric heating element, temperature controls, power supply system, and transport apparatus.

What Is The Purpose Of A Vacuum Hot Press Furnace?

The purpose of a vacuum hot press furnace is to combine vacuum or atmosphere, hot pressing, and high-temperature sintering to form new materials.

What Gas Is Used In A Vacuum Furnace?

Different gases can be used in a vacuum furnace depending on the application. In general, vacuum furnaces can work with gases or mixtures such as Argon, Nitrogen, Hydrogen, Carbon Monoxide, Helium, among others. The use of these gases allows for heat treatment in a defined, mostly non-oxidizing atmosphere, which is required for various applications such as vacuum soldering and brazing, vacuum annealing, and sintering. Additionally, it is possible to work with a defined oxygen concentration that is different from the air composition.

What Are The Advantages Of A Vacuum Hot Press Furnace?

Advantages of a vacuum hot press furnace include hot pressing sintering of metal and ceramic powders, preparation of ceramic/metal composites and intermetallic compounds, research and development of diffusion welding process, and densification hot press sintering of oxygen/nitrogen/boron/carbon compounds and their mixtures. The high temperature and pressure under vacuum or atmosphere help to bond raw materials solid particles together, decrease voids and grain boundaries, and improve the mechanical, electronic, and thermal properties of finished materials.

What Is The Heating Element Used In A Vacuum Furnace?

The heating element in a vacuum furnace is critical to its proper functioning, and is dependent on factors such as maximum operating temperature, power load, partial pressure and quench gases, and life expectancy. Vacuum furnaces are heated by electric resistance elements made from a variety of materials, including high-temperature metallic alloys such as stainless steel, nickel-chromium, molybdenum, tungsten, tantalum, or of non-metallic materials such as graphite and silicon carbide. The choice of material for the heating element is important in maximizing its longevity, reliability, efficiency, and ultimately the process results.

How Does A Vacuum Hot Press Furnace Work?

A vacuum hot press furnace is a piece of equipment that combines vacuum, hot pressing, and high-temperature sintering. It works by heating and pressurizing materials under vacuum or atmosphere to create a compact polycrystalline sintered body with improved mechanical, electronic, and thermal properties. The furnace is composed of several systems including furnace body, heating and heat preservation, temperature measurement system, vacuum system, air charging system, water cooling system, control system, and pressure system. Heating elements can be graphite heater, molybdenum heater, or induction heating, and one-way or two-way pressurization can be used for hydraulic pressurization.

What Are The Common Applications Of Vacuum Hot Press Furnaces?

Vacuum hot press furnaces have various applications in industries such as aerospace, automotive, electronics, and materials research. They are used for the production of advanced ceramics, such as ceramic matrix composites and sintered carbides, which are used in high-temperature applications.
