The Large-diameter Rotary Tube Furnace 1200°C - TT-RTF-300-1200 is designed for advanced material processing, featuring an integrated heating system, automatic rotation, automated feeding and discharging mechanisms, and a tiltable furnace body. The tube rotates 360° with adjustable speed to ensure uniform heating, while the feeding speed can be fine-tuned in real time for precise control. The furnace body tilts up to 15° to simplify material loading and unloading, making it efficient and user-friendly.
Equipped with a Φ300 quartz tube and a 440 mm heating zone, this model supports continuous operation at 1100°C and reaches a maximum temperature of 1200°C. Powered by 220V/13kW (with 110V option available), it utilizes high-quality alloy resistance wire (HRE) heating elements and an N-type thermocouple for reliable temperature measurement. A collection unit at the tube outlet enables continuous small-scale production, making this furnace ideal for research, pilot testing, and specialized industrial applications.

A solid double-layer metal frame combined with a heat-insulating fan structure ensures a low external surface temperature. The unit is designed for horizontal operation with a top-opening configuration for ease of use.
Refractory Material
- The furnace features a multi-layer insulation system made of lightweight alumina ceramic fiber and high-grade insulation board. It is asbestos-free, minimizing heat loss and energy consumption.
Heating System
- High-performance HRE spiral resistance wires are securely embedded along the inner surface, providing efficient thermal radiation heating and extended service life.
- Circular heating via resistance wire ensures uniform temperature distribution throughout the chamber.
Temperature Control Panel
- Equipped with advanced controllers designed to handle complex thermal processes.
- Supports up to 30 programmable segments for automated temperature control curves.
- Includes over-temperature protection, fault alarms, and automatic safety shutdown.
Rotary and Automatic Feeding System
- The furnace tube uses a gear-driven electric motor to rotate 360°, with adjustable speeds ranging from 12–20 RPM for even heating.
- The furnace body is electrically tiltable with an adjustable angle, allowing for smoother loading and unloading of materials.
- An integrated automatic screw feeder enables adjustable feeding speed and includes a material collection system at the discharge end, enabling continuous processing for small-batch production or experimental use.
