2.2 Effective Height: 40mm
2.3 Conveyor Belt Width: 385mm
2.4 Conveyor Belt Material: Cr20Ni80
2.5 Maximum Load: 35Kg/m² (excluding the weight of the conveyor belt)
2.6 Furnace Structure: Large chamber Inconel601 material muffle tube structure, with the muffle bottom fully covered with support boxes to enhance rigidity (the muffle bottom is fully covered with dispersion gas boxes)
2.7 Drive System: Large wrap angle friction drive
2.8 Speed Range: 30~200mm/min, variable frequency stepless speed control
2.9 Heating Elements: Ceramic fiber heating modules
2.10 Sintering Atmosphere: Nitrogen + Oxygen

Heating Zone ≤15ppm + gas source oxygen content
High-Temperature Zone ≤10ppm + gas source oxygen content
Cooling Zone ≤10ppm + gas source oxygen content
Cooling Zone ≤15ppm + gas source oxygen content
2.14 Exhaust System: One exhaust pipe is installed at the inlet transition sleeve (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: ±1ºC
2.18 Furnace Temperature Uniformity: ±2ºC (in the constant temperature zone, across the width of the conveyor belt)
2.19 Heating Rate: ≤2ºC/min
2.20 Number of Temperature Zones: 11
2.21 Temperature Control Points: 33 (independent control for left, middle, and right in each temperature zone)
2.22 Front Section Thermocouple Type: K Type (for Zones 1 to 4)
2.23 Rear Section Thermocouple Type: S Type (for Zones 5 to 11)
2.1 Alarm Indicators: Over-temperature, under-temperature, frequency converter alarm, thermocouple break, low air pressure, low water pressure, conveyor belt over-length, etc., with audible and visual alarms
2.2 Power Failure Protection: Equipped with a manual crank-out device
2.3 Belt Stop Protection: Emergency stop buttons installed at both the inlet and outlet end plates
2.4 Surface Temperature Rise: <35ºC
2.5 Heating Power: Approximately 88kW
