| Item | Description |
|---|---|
| Max operating temperature | 1000℃ |
| Long-term continuous temperature | 700-900℃ |
| Temperature control range | 100-1000℃ |
| Chamber dimension | 500×500×500mm |
| Temperature control accuracy | ±1℃ |
| Temperature sensor | K-type thermocouple |
| Heating element material | High-temperature alloy resistance wire |
| Heating element arrangement | 4-sided heating |
| Inlet & exhaust port | Fully automatic. Protective atmosphere available. Electric inlet and exhaust ports can be linked with heating curve to auto turn on/off at any temperature segment |
| Heating rate | Min 10-30℃/min; Recommended actual heating/cooling rate:1-15℃/min |
| Furnace body structure & material | Air-cooled double-layer carbon steel furnace body with air cooling guide partition. Cold air circulates integrally, cools heating element conducting strips before discharge to prevent high-temp oxidation |
| Exhaust system | Stainless steel fan with auxiliary chimney for forced exhaust |
| Observation window | Min size:30×35mm, quartz glass |
| Door opening method | Motorized top opening door |
| Refractory & insulation material | Vacuum molded high-purity alumina lightweight material. Low heat storage, thermal shock resistant, no cracking or slag falling, excellent thermal insulation |
| Shell temperature | Shell temperature ＜40℃ |
| Safety protection | Integrated modular control unit, dual-loop control and dual-loop protection. Protection functions: overshoot, under-adjustment, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, soft start |
| Power cut-off on door opening | Main heating circuit cuts off automatically when door opens at high temperature to prevent electric shock risk during high-temp material taking |
| Safety temperature control | Closed-loop SCR module trigger control, phase-shift trigger or zero-crossing trigger. Continuously adjustable output voltage/current/power; constant voltage / constant current / constant power mode. Current as inner loop, voltage as outer loop. Limits output current within rated range under sudden load or over-limit current, protects heating element from heavy current & voltage impact to guarantee reliable control and precision |
| Temperature curve setting | Intelligent temperature controller, multiple control modes including standard PID, artificial intelligence APID or MPT. Auto-tuning & self-learning, excellent performance without overshoot or undershoot. 50-segment program control, arbitrary ramp up/down slope. Support jump(cycle), run, pause, stop; program can be modified anytime during running. AI algorithm with curve fitting for smooth temperature curve |
| Program segments | Total 50 segments. Options:1 curve with 50 segments / 2 curves ×28 segments each /3 curves ×15 segments each /5 curves ×9 segments each. Multiple curves can be stored and called freely |
| Panel buttons | Main power button/knob, heating chamber switch button/knob |
| Supplied accessories | 1 crucible tongs, 2 pairs high temperature gloves, 1 furnace bottom plate |
| Warranty scope & period | 1-year free warranty for whole furnace. Furnace bottom plate excluded; Heating element free replacement for natural damage within 3 months |
| Packing list | 2 pairs high temperature gloves,1 corundum furnace bottom plate,1 crucible tongs,1 operation manual,1 warranty card,1 operation training document,1 delivery note & equipment acceptance form |
