Product Features
- Large-format, openable furnace tube design
Features a stainless steel furnace tube with a diameter of 159 mm and a length of 2000 mm, offering an effective heating zone of 1500 mm; this accommodates large samples, long workpieces, and batch material processing for high-temperature experiments.
The furnace door utilizes a vertical opening design, facilitating easy sample loading/unloading and experimental operations.
- Independent dual-zone temperature control
The equipment employs a dual-zone control structure with heating elements arranged around the furnace tube, enhancing temperature distribution stability within the furnace.Temperature uniformity reaches ±1°C (actual uniformity varies based on furnace dimensions, experimental temperature, and loading conditions).
- Wide-range heating rate adjustment
Heating rates can be freely configured according to experimental protocols, ranging from a maximum of approximately 15°C/min down to a minimum of 1°C/h.
This broad control range meets diverse experimental needs, including material preheating, slow ramping, high-temperature holding, and programmed heat treatment.
- Intelligent programmable temperature control
Equipped with an intelligent temperature controller supporting multiple regulation modes—such as standard PID, AI-based APID, and MPT—along with auto-tuning, self-learning, and curve-fitting capabilities.
The system supports 30-segment program control, enabling heating and cooling at arbitrary rates, as well as functions like program jumping, looping, running, pausing, and stopping; multi-segment temperature curves can be customized to specific experimental requirements.
- Dual-layer air cooling and multi-layer insulation structure
The furnace body features a dual-layer air-cooled design; air-guiding baffles circulate cool air within the shell, effectively lowering the temperature of the furnace body and the conductive components of the heating elements.
The furnace lining utilizes vacuum-formed, high-purity, lightweight alumina insulation, combined with aluminum silicate fiber board, alumina fiber board, and polycrystalline alumina fiber board to create a three-layer insulation structure. This design offers low heat storage, resistance to thermal shock (rapid heating/cooling), crack resistance, and superior thermal insulation performance.
Under continuous long-term operation, the external furnace shell temperature is maintained below 45°C.
