Introduction
Vertical tube furnaces are laboratory equipment used for high-temperature processing of materials under controlled atmospheric conditions. They consist of a vertically oriented quartz tube enclosed within a heating chamber, which allows for precise temperature control and uniform heat distribution. These furnaces are commonly employed for various applications, including heat treatment, quenching, annealing, crystal growth, and chemical vapor deposition (CVD) coating. With advanced features such as programmable temperature controllers, vacuum sealing capabilities, and specialized accessories for sample manipulation, vertical tube furnaces offer versatility and accuracy in materials processing. Their ability to create controlled atmospheres and achieve high temperatures makes them essential tools in research and development, materials science, and industrial applications.
Applications
Vertical tube furnaces are versatile heating devices with a wide range of applications in various industries and laboratory settings. They are particularly useful for processes that require precise temperature control and the ability to operate under vacuum or controlled gas atmospheres.
- Gas Quenching Tests: Vertical tube furnaces are commonly used for gas quenching tests, where samples are rapidly cooled from high temperatures into a quenching medium such as ice water or oil. This allows researchers to study material phase transitions and the effects of rapid cooling on material properties.
- Heat Treatment: Vertical tube furnaces are used for a variety of heat treatment processes, including annealing, tempering, and stress relieving. These processes can improve the mechanical properties of materials, such as their strength, hardness, and ductility.
- Chemical Vapor Deposition (CVD): Vertical tube furnaces are used for CVD processes, where a thin film is deposited on a substrate by chemical reactions in a gaseous environment. This technique is commonly used in the semiconductor industry to create electronic devices.
- Crystal Growth: Vertical tube furnaces are used for crystal growth, where crystals are grown from a molten or vapor phase. This technique is used to produce high-quality crystals for use in optics, electronics, and other applications.
- Materials Testing: Vertical tube furnaces are used for materials testing, such as thermal conductivity measurements, melting point determinations, and phase transitions. These tests provide valuable information about the properties of materials.
- Other Applications: Vertical tube furnaces are also used in various other applications, including:
- Sintering
- Brazing
- Calcination
- Ceramics
- Glassworking
- Laboratory research
- Powders processing
Detail&Parts
2. Electronic digital display panel: accurate temperature control, preset multi-stage heat treatment process.
3. Alumina polycrystalline fiber hearth: high temperature resistance, long use without deformation, no cracking.
Principle
Vertical tube furnaces operate on the principle of radiant heat transfer. The heating element, typically made of molybdenum disilicide (MoSi2) or silicon carbide (SiC), is located around the vertical tube, emitting infrared radiation that is absorbed by the sample inside. This radiation heats the sample uniformly, providing precise and efficient temperature control. The furnace's design allows for rapid heating and cooling rates, making it suitable for various applications, including material synthesis, heat treatment, and temperature measurements.

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.
