Sealed Quartz Tube Rotary Furnace

The 1200℃ sealed quartz tube rotary furnace :is an experimental equipment specially designed for uniform heat treatment of powder materials.

 It adopts a high-purity quartz tube reaction chamber and can perform dynamic sintering, synthesis, annealing and other processes in a vacuum or controllable atmosphere (inert/reactive gas) environment. The rotary design ensures uniform heating of samples and avoids agglomeration, making it suitable for research fields such as nanomaterials, battery positive and negative electrodes, and catalysts.

Core Features

• High-temperature rotation system – 0-30 RPM adjustable speed to ensure uniform mixing of materials
• Sealed quartz tube – high-purity quartz tube (Φ60-100mm), high temperature resistance, corrosion resistance
• Double-ended sealing design – magnetic fluid seal / flange seal, supporting high vacuum (10⁻³ Pa)
• Precise temperature control – PID intelligent regulation, temperature control accuracy ±1℃, multi-segment program heating
• Atmosphere control – supports Ar, N₂, H₂, CO and other gases, with flow control
• Safety protection – over-temperature protection, air leakage alarm, power-off memory

Additional Equipment

• Lift door：Pneumatic door opening, controlled by foot pedal, with hot surface facing away from the operator.
• Touchscreen: Multilingual menu, multiple temperature rise process curve storage, historical curve storage, and data reports (7 inches).
• Computer Control: Controls furnace start, pause, stop, stores historical curves, sets temperature rise curves, reads temperature rise curves, sets parameters, etc.
• Siemens PLC Control: Real-time data reading with open ports for data communication with upstream and downstream equipment.
• Manual or automatic gas supply system
• Observation Window: Designed on the furnace door with high-temperature-resistant quartz glass.
• Movable Casters: Two swivel casters and two fixed casters.
• Rapid Cooling: Achieved with a frequency inverter and centrifugal fan for programmable cooling control.
• Quick Discharge Rack: The material rack is made of high-temperature steel, with wear-resistant heavy-duty refractory bricks on the top, enabling rapid
• transfer of materials from the furnace to an external platform in high-temperature environments.
• Multi-Point Temperature Control: Independent temperature control on multiple sides for improved temperature uniformity.
• High temperature furnace chamber with multi-sided heating for very good temperature uniformity.
• Stirring Fan: Metal stirring fan, can be linked with PLC to automatically start at designated temperature segments.
