Equipment features:
1. Lining material: low pollution, high strength, suitable for clean sintering needs
The use of vacuum formed high-purity alumina lightweight material to construct the core insulation layer of the furnace has significant advantages compared to traditional ceramic fiber materials
Efficient insulation and energy saving: With the double-layer furnace shell air-cooled design, it can save more than 30% energy compared to traditional equipment and maintain long-term temperature stability inside the furnace;
2. Heating element: Resistance wire partition layout, suitable for multi-stage processes
Selecting high-purity nickel chromium alloy resistance wire as the heating element, optimizing the design based on the characteristics of co sintering process:
Accurate temperature coverage: can achieve wide range temperature control from room temperature to 1700 ℃, perfectly matching the entire process of SOFC stack co sintering
Controllable heating rate
4. Pressure control accuracy: adapted to interlayer densification requirements
Equipped with a high-precision pressure sensing system and servo driven actuator, forming a closed-loop pressure control system:
Dynamic feedback compensation: The pressure sensor collects data in real-time at a frequency of 10Hz. When the high-temperature sintering expansion of the fuel cell generates a reaction force, the system automatically compensates for the pressure deviation (compensation response time<0.5s) to avoid interlayer delamination or pore formation.
5. Pressure application method: Suitable for large-area stack production
Adopting a "flexible pressure plate+multi-point synchronous pressure" structure, optimized for different specifications of fuel cells:
6. Accurate control of atmosphere: solving material compatibility problems
Integrated multi-channel atmosphere control system to address the atmosphere sensitivity issue in SOFC sintering:
Multi atmosphere compatibility: nitrogen, argon (inert protection), hydrogen argon mixed gas (reducing atmosphere) can be introduced to meet the dual requirements of MS-SOFC metal support oxidation prevention and Ni based anode reduction sintering, avoiding the decomposition of traditional cathode materials (such as LSM) in reducing atmosphere;
7. Artistic integration capability: achieving one-stop co sintering
Deeply integrate temperature, pressure, and atmosphere control to adapt to SOFC scale production:
Rich program storage: supports storage of 50-100 sets of process curves, can preset the full process parameters of "temperature rise pressure insulation pressure drop temperature", and achieve automated production with one click calling, reducing manual operation errors;
8. Intelligent and secure systems: ensuring efficient and stable operation
Intelligent control: improving operational and traceability efficiency
Convenient human-computer interaction: 7-inch touch screen supports parameter setting and process monitoring, equipped with data storage function (can export sintering logs in Excel format), some models can be connected to MES system for remote monitoring, adapting to the production needs of Industry 4.0;
Complete self diagnostic function: It can automatically detect faults such as aging of heating elements, abnormal pressure sensors, and atmosphere leaks, issue sound and light alarms, and display fault points, reducing maintenance difficulty.
