2.3 **Belt Width**: 385mm  
2.4 **Belt Material**: Cr20Ni80  
2.5 **Maximum Load**: 20Kg/m² (excluding the weight of the belt)  
2.6 **Furnace Structure**: Large furnace chamber with SUS310S muffle tube structure. The muffle bottom is fully covered with support boxes to enhance rigidity (dispersion gas boxes are also installed at the bottom).  
2.7 **Transmission System**: Large wrap-angle friction drive  
2.8 **Speed Adjustment Range**: 50～400mm/min, stepless speed regulation by frequency converter  
2.9 **Heating Elements**: Ceramic fiber heating modules  
2.10 **Sintering Atmosphere**: Nitrogen + Oxygen  
2.11 **Gas Circuit Composition**: Each gas path is adjustable (refer to Section 3.2 for technical details).  
2.12 **Oxygen Content Detection Points**:  
   - Detection points include nitrogen gas source, Zone 2, Zone 4, Zone 6, cooling zone, final cooling zone, and nitrogen-oxygen mixed gas source (4 points).  
   - A total of 10 stainless steel detection pipelines are connected in parallel to the oxygen analyzer. Electromagnetic valves are used to switch detection points, enabling real-time monitoring of oxygen content in the furnace and facilitating adjustment of gas intake.  
2.13 **Oxygen Content** (analyzed online with oxygen analyzer, tested under pure nitrogen atmosphere):  
   - Zone 2: ≤15ppm + gas source oxygen content  
   - Zone 4: ≤10ppm + gas source oxygen content  
   - Zone 6: ≤10ppm + gas source oxygen content  
   - Cooling Zone: ≤10ppm + gas source oxygen content  
   - Final Cooling Zone: ≤15ppm + gas source oxygen content  
2.14 **Exhaust System**: One exhaust pipe is installed at each of the inlet and outlet transition sleeves (refer to Section 3.2 for technical details).  
2.15 **Cooling Method**: Combined air and water cooling, with one water temperature detection point in the cooling water jacket.  
2.16 **Structural Division**: Refer to Section 3.1 for technical details.  
2.17 **Temperature Control Stability**: ±1°C  
2.18 **Furnace Temperature Uniformity**: ±3°C (constant temperature zone, cross-section direction of the belt width)
