A tube furnace is a heating device with a tubular furnace structure ..

Common Categories

According to structure and form, it can be divided into horizontal, vertical, and openable types. Among them, the horizontal tube furnace is the mainstream type for laboratory and small-scale production due to its convenient loading and unloading of materials; There are also styles such as single tube and double tube, and the double tube type can process two sets of samples simultaneously, improving efficiency.

Divided by temperature zone: covering single temperature zone, double temperature zone, triple temperature zone, and multi temperature zone. Multi temperature zone tube furnace can form gradient temperature in different sections of the furnace tube, suitable for special experiments that require step-by-step temperature control, such as material segmented sintering, multi-step chemical reactions, and other scenarios.

According to functional characteristics: including ordinary tube furnace, vacuum tube furnace, atmosphere tube furnace, rotary tube furnace, etc. Vacuum tube furnaces can achieve low-pressure environmental treatment, while atmosphere tube furnaces can introduce gases such as nitrogen and argon to prevent material oxidation.

Core strengths

Accurate and efficient temperature control: High efficiency heating elements such as resistance wires are often used, combined with digital control systems. Some can support 30 segment programmable temperature control, with high temperature control accuracy and the ability to quickly raise the temperature to the target temperature. At the same time, the heat inside the furnace tube is transferred through radiation and convection, and the material is uniformly heated.

Compact and easy to operate structure: The overall volume is small, occupying a small area, making it easy to flexibly arrange in the laboratory or workshop. It also adopts modular design, with an intuitive operation interface, simple loading and unloading process, and convenient replacement of parts during later maintenance.

Versatile adaptation scenarios: The furnace tube can be made of different materials such as quartz, ceramics, heat-resistant steel, etc., combined with vacuum or atmosphere systems, which can meet the needs of ordinary heating, as well as adapt to special processes such as inert atmosphere and vacuum, and adapt to various material processing.

Main application areas

Research experiment field: It is the core experimental equipment of universities and research institutes, commonly used for material thermal performance testing, chemical reaction kinetics research, new material synthesis, etc., such as performance improvement experiments of semiconductor materials, preparation research of new catalysts, etc.

In the field of new energy, high-temperature sintering or modification treatment is carried out for lithium positive and negative electrode materials, photovoltaic related materials, etc., to help improve the stability and performance of new energy materials, and to adapt to small-scale trial production and process optimization in the new energy industry.

In the field of metallurgy and material processing, it is used for annealing and quenching of metal parts, sintering of ceramic bodies, and heat treatment of materials such as grinding tools and glass. It can ensure uniform performance of materials during heating and improve product quality.

In the field of chemical synthesis, providing a stable high-temperature environment for organic and inorganic synthesis reactions, such as cracking reactions of some organic compounds and preparation of special inorganic compounds, can improve product purity and reaction yield.
