1.Accurately match experimental requirements and break through the limitations of standard equipment
Temperature gradient control
Multi zone independent temperature control: 2-5 independent temperature zones can be customized, and the temperature range (such as room temperature to 1700 ℃) and heating rate of each zone can be set separately to achieve precise temperature gradient distribution.
Application scenario: In graphene synthesis, the carbon source is cracked in the first high-temperature zone (1000 ℃), and the ordered growth is promoted in the second low-temperature zone (600 ℃) to avoid disorderly stacking.
Improved temperature control accuracy: Customize PID algorithm or fuzzy control technology to control temperature fluctuations within ± 1 ℃, meeting the temperature sensitive experimental needs of semiconductor materials, catalysts, etc.

Optimization of rotation and tilt functions
Adjustable rotation speed: Supports 0-15rpm stepless speed regulation to ensure uniform heating of powder, liquid, or film samples.
Case: A certain university customized a rotary tube furnace to process ceramic powder at a speed of 5rpm, which increased the density of the sintered body by 12% and reduced the porosity to below 3%.
Tilt angle customization: adjustable design from 0 ° to 90 °, suitable for special processes such as gas exchange and liquid dripping.
Application: In chemical vapor deposition (CVD), a 30 ° tilt angle is used to promote gas flow on the sample surface, improving the uniformity of the deposition layer to over 95%.

2.Flexibly adapt to sample characteristics and expand application boundaries
Customization of furnace tube size and material
Diameter and length expansion: Customize furnace tubes according to sample size (such as Φ 200mm × 1500mm), supporting large workpieces or batch processing.
Industrial case: A certain enterprise customized a large-diameter tube furnace that can process 50kg of metal powder in a single operation, increasing production efficiency by three times.
Material selection: Quartz tube (transparent observation, corrosion-resistant), stainless steel tube (high temperature strength), or corundum tube (resistant to rapid cooling and heating) can be configured as needed.
Research application: In experiments with strong corrosive atmospheres (such as Cl ₂), using Hastelloy furnace tubes can extend the service life to more than 5 years.

Upgrade of atmosphere control system
Multi gas injection and mixing: Supports independent control of 3-5 gas channels, with precise proportional adjustment through a mass flow meter (MFC) (e.g. H ₂: Ar=1:9).
Energy field: In the preparation of fuel cell catalysts, customized H ₂/Ar mixed atmosphere is used to narrow the particle size distribution of Pt nanoparticles (D50=2.5nm ± 0.3nm).
Vacuum degree improvement: equipped with a dual stage vacuum pumping system of mechanical pump and molecular pump, with a maximum vacuum degree of ≤ 10 ⁻⁴ Pa, to meet the requirements of high-purity material synthesis.
Semiconductor case: In SiC epitaxial growth, vacuum environment can reduce impurity doping and lower defect density to below 10 ⁵ cm ⁻ ².

3.Improve experimental efficiency and safety, and reduce overall costs
Rapid heating and cooling
Customization of heating power: Choose a heating power of 10-50kW according to the furnace volume to shorten the heating time (such as only 30 minutes from room temperature to 1200 ℃).
Water cooling jacket design: By circulating cooling water to accelerate cooling, the experimental cycle is shortened by 40%, making it suitable for continuous production scenarios.
Industrial data: A certain photovoltaic enterprise customized a water-cooled tube furnace, and the daily production capacity of a single line increased from 200kg to 350kg.

Enhanced security protection
Multiple alarm system: automatic alarm and power cut-off for faults such as overheating, gas interruption, and leakage, to avoid equipment damage or personnel injury.
Explosion proof structural design: The furnace body adopts explosion-proof doors and pressure relief valves to ensure safety in flammable atmosphere experiments such as hydrogen gas.
Research support: A university laboratory successfully avoided three potential explosion accidents by customizing an explosion-proof tube furnace.

Modularity and Scalability
Reserved interface design: Supports future upgrades to automation control systems and online monitoring modules (such as infrared temperature measurement and gas analyzers).
Expansion capability of temperature zone: Initially customized equipment with 2 temperature zones, it can be expanded to 4 temperature zones through the installation of heating modules in the later stage to protect investment.
Long term plan: A research institute will customize tube furnaces in stages, gradually increasing experimental capabilities according to demand within 5 years, and reducing total costs by 25%.

4. Customized cases and data support
Materials synthesis field
Case: A material laboratory customized a three temperature zone rotary tube furnace for synthesizing two-dimensional transition metal sulfides (2D TMDs).
Effect: By using sulfurized metal precursor in the high temperature zone (800 ℃) in the front section, controlling the number of layers in the medium temperature zone (500 ℃) in the middle section, and annealing in the low temperature zone (300 ℃) in the back section, the yield of single-layer MoS ₂ was increased from 15% to 68%.

Energy storage field
Case: A battery company customized a vacuum atmosphere rotary tube furnace for the preparation of negative electrode materials (Si/C composite) for lithium-ion batteries.
Effect: Through rotational heat treatment in Ar atmosphere, Si particles were uniformly dispersed in the carbon matrix, and the initial charge discharge efficiency increased from 72% to 89%. After 100 cycles, the capacity retention rate reached 91%.

Semiconductor manufacturing field
Case: A chip manufacturer customized a high vacuum multi temperature zone tube furnace for GaN epitaxial growth.
Effect: By precisely controlling the ratio of NH3/N ₂ atmosphere and temperature gradient, the dislocation density of epitaxial layers is reduced to 5 × 10 ⁶ cm ⁻ ², and the luminous efficiency of LED devices is improved by 30%.
