Product Features
- Shaped 310S Stainless Steel Furnace Tube with Internal Material-Turning Flights
The furnace tube is made of custom-formed 310S stainless steel, featuring a central section measuring φ500 × 2500 mm (equipped with internal lifting flights) and end sections measuring φ159 × 350 mm. As the tube rotates, the lifting flights continuously lift and tumble the material, effectively preventing wall adhesion and agglomeration.
- Adjustable Tilt and Rotation for Convenient Discharge
The tilt angle is adjustable from 0 to 10 degrees, and the rotation speed ranges from 0 to 5 rpm. By coordinating the tilt angle and rotation speed, the residence time and travel speed of the material within the tube can be precisely controlled.
- Independent Temperature Control Across Three Zones (Left, Middle, Right)
Three independent temperature control zones (left, middle, and right) ensure uniform furnace temperature. Temperature control precision is ±1°C, with an adjustable heating rate ranging from 1°C/h to 15°C/min. Heating elements consist of Shougang HER high-temperature alloy resistance wire, installed around the furnace tube.
- Steam Evaporator and Comprehensive Atmosphere System
Equipped with a steam evaporator (flow rate controllable from 5 to 50 g/min); the 316L inlet pipe features external insulation and pipeline heating. Two flow meters are included, supporting flow rates of 0–20 L/min for nitrogen and carbon dioxide. The system supports various atmospheres, including nitrogen, carbon dioxide, and steam.
- Flange Sealing with Rotary Joint and Overpressure Safety Valve
Flange seals combined with rotary joints ensure gas-tight integrity during tube rotation. Gas flow is controlled by inlet and outlet valves, while an overpressure safety valve prevents excessive system pressure. A digital pressure gauge is provided for real-time monitoring of the internal furnace pressure.
