Customized vertical tube furnace is a commonly used equipment for high-temperature heat treatment experiments and small-scale production in universities, research institutes, new material research and development institutions, powder material processing, and metallurgical and chemical enterprises. Different from conventional standard size tube furnaces, customized vertical tube furnaces are designed one-to-one according to users' actual process requirements, experimental material characteristics, on-site installation space, and sintering temperature requirements. Whether it is furnace structure, furnace size, heating temperature, temperature control method, or vacuum atmosphere configuration, they can be matched as needed, truly achieving process adaptation, experimental stability, and production usability. Vertical structure design is more suitable for processes such as powder particle sintering, material settling reaction, vapor deposition experiment, and atmosphere reduction treatment. It is also a mainstream and commonly used high-temperature electric furnace equipment for CVD experiments, new material modification, and special ceramic sintering.

1. Why are more and more customers choosing customized vertical tube furnaces
The ordinary standard vertical tube furnace on the market has fixed parameters, single size, and uniform configuration, which can only meet the basic simple heat treatment needs. Many scientific research experiments and industrial sintering processes have special requirements for heating zone length, furnace tube diameter, working temperature, atmosphere piping, temperature rise and fall curves, and inlet and outlet structures. Standard equipment cannot achieve experimental results, which can easily lead to problems such as uneven sintering, temperature non-compliance, poor sealing, gas leakage, and insufficient material reaction.
Choosing a customized vertical tube furnace can be completely customized according to its own process conditions, without the need to accommodate equipment parameters, allowing the equipment to adapt to the experiment, rather than the experiment accommodating the equipment. Whether it is a small laboratory micro vertical tube furnace or a large diameter, large heating zone, high-temperature continuous operation industrial grade vertical tube furnace, it can be customized according to needs, effectively improving the success rate of experiments, improving sample consistency, and ensuring stable quality of sintered products.

2. What core configurations can be customized for a customized vertical tube furnace
Customized vertical tube furnaces support full dimensional non-standard personalized customization, and all core components and functional configurations can be adjusted and modified according to user needs. The customization scope is comprehensive and suitable for various complex high-temperature heat treatment processes.
Temperature parameters can be customized: from conventional 1000 ℃, 1200 ℃, 1400 ℃ to 1600 ℃, 1700 ℃ ultra-high temperature versions can be customized. Long term continuous working temperature and short-term peak temperature can be matched as needed, with stable heating and uniform temperature field.
The size of the furnace body and furnace chamber can be customized: the diameter of the furnace tube, the effective heating length of the furnace tube, the height of the furnace chamber, and the overall external dimensions of the furnace body can all be customized according to the installation space on site. The vertical structure does not take up space and can be placed and installed flexibly. The furnace adopts good high-temperature insulation materials, with a reasonable layout of embedded heating elements, uniform heating, and long-term high-temperature use without slag, deformation, or material pollution.
The temperature control system can be customized: it can be equipped with an intelligent touch screen temperature control instrument, using PID intelligent adjustment and self-tuning functions, supporting multiple programmable temperature rise and fall programs, and can set dozens of process curves. The temperature is controllable, and experimental data can be stored, viewed, and exported, making it convenient for scientific research data retention and process repeated calling.
The vacuum and atmosphere system can be customized: a two-stage vacuum pump set can be installed to achieve a high vacuum environment, supporting multiple air inlet ratios, and can be filled with protective atmospheres such as nitrogen, argon, and hydrogen to meet the requirements of vacuum sintering, atmosphere sintering, reduction heat treatment, and high-temperature oxidation prevention processes. It has good sealing performance, no air leakage, and stable pressure holding.

3. Customized vertical tube furnace is mainly suitable for industries and processes
Customized vertical tube furnaces have a wide range of applications, suitable for scientific research experiments and small-scale mass production, and are adaptable to various high-temperature heat treatment processes. The School of Materials Science and Technology and research institutes of universities focus on research and development of new materials, graphene growth and preparation, CVD chemical vapor deposition experiments, high-temperature modification of powder materials, sintering of special ceramics, sample annealing and tempering, and other scientific research experiments. Industrial and mining enterprises, as well as new material factories, are mostly used for production and processing work such as metal powder metallurgy sintering, rare metal material heat treatment, high-temperature purification of carbon materials, particle material roasting, and precision heat treatment of electronic components.
The vertical tube furnace has a vertical furnace structure, where materials naturally settle by gravity, resulting in more complete reactions and more uniform heating during sintering. This effectively avoids problems such as material accumulation, local overheating, color difference during sintering, and poor experimental repeatability. The experimental data is stable and reliable, and the process has strong reproducibility.
