1. Technical features: Integration of good temperature control and uniform heating
Three temperature zone independent control
The equipment is equipped with three independent heating zones, each of which can be individually set in temperature (such as 1700 ℃ in the central zone and 1400 ℃ on both sides), forming a good temperature gradient. For example, in the preparation of functional materials, directional growth under thermal gradient can be achieved by adjusting the temperature zone to avoid cracking or performance differences caused by uneven temperature.
Rotating heating mechanism
The furnace tube can rotate clockwise or counterclockwise (with adjustable speed) to promote uniform distribution of atmosphere inside the furnace and enhance the surface heat exchange efficiency of the material. For example, in powder metallurgy processes, rotary heating can make the powder particles heated more evenly, react more fully, and improve material density.
Good insulation and energy-saving design
The furnace is made of high-temperature resistant materials such as high-purity alumina fibers or corundum tubes, combined with a double-layer shell and air cooling system, with a surface temperature below 60 ℃ to reduce heat loss. Some models use silicon molybdenum rods for heating, which has lower energy consumption and is in line with the trend of green production.
Intelligent operation and security protection
Equipped with PID intelligent temperature control system, supporting 30 stage program temperature control, with a temperature control accuracy of ± 1 ℃. At the same time, it integrates multiple protection functions such as overheating, disconnection, and overpressure to ensure that the equipment automatically shuts down in case of abnormal situations, ensuring operational safety.

2. Application scenario: covering the needs of multiple fields of scientific research and industry
material preparation
Nanomaterial synthesis: directional growth of one-dimensional materials such as nanowires and fibers is achieved through temperature gradient control.
Ceramic sintering: Rotating heating promotes uniform shrinkage of ceramic particles, reduces defects, and improves sintering quality.
Metal heat treatment: Reduction of metal oxides in a reducing atmosphere (such as hydrogen) to prepare high-purity metal powders.

semiconductor process
Thin film epitaxial growth: using CVD method to deposit thin films under temperature gradient, controlling lattice matching and improving device performance.
Wafer Annealing: Vertical airflow design reduces temperature fluctuations, ensuring that the temperature difference on the wafer surface is controlled within ± 5 ℃, meeting the precision requirements of semiconductor manufacturing.

Research on Chemical Catalysis
Catalyst preparation: Rotating heating evenly decomposes the catalyst precursor, optimizes the pore structure, and improves catalytic activity.
Gas phase reaction: The multi-channel atmosphere control system can introduce protective gases such as nitrogen and argon to prevent oxidation of reactants and improve product purity.
