The HWF80-04N is a research-grade medium-temperature thermal processing system specifically designed for sintering and hydrogen removal processes of electronic materials in nitrogen/vacuum environments. Equipped with PLC intelligent control and real-time monitoring systems, it meets the high-precision requirements for material process R&D.
Basic Performance
| Parameter | Specification |
|-------------------------|--------------|
| Effective Work Area | 400(W)×400(H)×500(D)mm |
| Rated Temperature | 350°C (vacuum) / 250°C (nitrogen) |
| Maximum Temperature | 400°C (vacuum only) |
| Temperature Uniformity | ±5°C (at 350°C for 1h, empty furnace) |
| Temperature Control Accuracy | ±1°C (PID auto-tuning) |
| Heating Rate | ≤5°C/min (programmable) |
Heating & Control System
• Heating Method: Stainless steel heating tubes + forced hot air
circulation (dual-zone independent temperature control)
• Total Power: 15kW (3-phase 380V±10%, 50Hz)
• Control Module:
o Touchscreen + PLC centralized control (supports process curve
storage/recall)
o Real-time monitoring with K-type thermocouples (reserved
detection ports)
Atmosphere & Safety
| Parameter | Specification |
|----------------------|--------------|
| Applicable Atmosphere | High-purity nitrogen (≤250°C), vacuum
(max. 400°C) |
| Vacuum Leak Rate | ≤0.67Pa/h |
| Alarm Protection | Audio-visual alarms for
overtemperature/thermocouple failure/insufficient water
pressure/vacuum anomalies |
Structural Parameters
• Dimensions: 1500×1950×1750mm (including control system)
• Power Requirements: ≥22kVA, 3-phase 5-wire system (with grounding
protection)
• Vacuum environment: Electronic ceramic sintering, metal powder
dehydrogenation (350-400°C)
• Nitrogen protection: MLCC annealing, anti-oxidation treatment of
magnetic materials (≤250°C)
• Strictly avoid exceeding 250°C in nitrogen atmosphere to prevent
heating tube oxidation failure
• Regular calibration of thermocouples and vacuum seals is
recommended
