Laboratory 1200°C Rotary Rocking Tube Furnace

Automated Rotary and Tilting Tube Furnace for Powder Heat Treatment

Laboratory 1200°C Rotary Rocking Tube Furnace

The Laboratory 1200°C Rotary Rocking Tube Furnace is a highly automated thermal processing system designed for the heat treatment, calcination, sintering, reduction, and reaction of powder materials under controlled temperature and atmosphere conditions.

Combining continuous tube rotation, rocking motion, and adjustable furnace tilting, this rotary tube furnace promotes uniform movement of powder materials inside the reaction tube. During operation, the materials undergo both radial and axial tumbling, improving heat transfer and gas-solid contact while helping to achieve more uniform thermal treatment.

Automated Rotary and Tilting Tube Furnace for Powder Heat Treatment

Introduction:

The system is widely used for the preparation and processing of lithium-ion battery cathode and anode materials, rare earth materials, chemical catalysts, magnetic materials, metal powders, and hydrogen reduction processes.

Equipped with a high-purity quartz tube, integrated lifting scraper structure, dynamic sealing system, and automatic touchscreen control, this laboratory rotary rocking tube furnace can be configured for operation under vacuum, inert gas, reducing gas, or other controlled atmospheres.

Features:

1. Rotary and Rocking Motion for Uniform Heat Treatment

The reaction tube continuously rotates and oscillates during operation, causing powder materials to tumble in both radial and axial directions. This movement helps improve material mixing, temperature uniformity, and contact between the powder and process gas.

Compared with conventional static sintering, the rotary rocking design can help reduce problems associated with uneven heating, localized overheating, over-sintering, or incomplete sintering.

2. Adjustable Tilting Angle

The furnace body can be tilted from -5° to 30°, allowing users to adjust the material movement and residence behavior inside the tube.

The tilting design also makes material loading and unloading easier, improving operational convenience for laboratory and pilot-scale powder processing.

3. High-Purity Quartz Reaction Tube

The furnace is equipped with a high-purity quartz tube suitable for high-temperature laboratory applications. An embedded lifting scraper structure helps continuously lift and turn the powder during tube rotation, supporting more uniform exposure to heat and process gases.

4. Excellent Thermal Insulation and Energy Efficiency

The furnace chamber uses high-purity Al₂O₃ ceramic fiber insulation, providing excellent thermal insulation performance and reduced heat loss.

This lightweight insulation structure helps improve heating efficiency and reduce overall power consumption.

5. Vacuum and Controlled Atmosphere Capability

An advanced dynamic sealing system allows the rotary tube furnace to operate under controlled process conditions, including:

Vacuum
Air
Nitrogen
Argon
Hydrogen or reducing atmospheres
Other customized process gases

This makes the furnace suitable for a wide range of powder sintering, calcination, reduction, and atmosphere heat treatment applications.

6. Fully Automatic Control System

The system features a fully automatic control system with a 7-inch touchscreen interface.

Users can monitor and control important operating parameters in real time, including:

Furnace temperature
Heating program
Tube rotation
Rocking operation
Furnace tilting angle
Process status
Gas and vacuum system status

The programmable control system provides improved repeatability and convenience for laboratory research and pilot-scale production.
