| Heating Rate | Max. heating rate: 40°C/min (non-linear) | |||||
| Furnace Structure & Material | Air-cooled double-layer carbon steel structure. Effective air-guiding baffles enable overall cold-air circulation inside the furnace shell, cooling the heating element terminals before exhausting. This prevents high-temperature oxidation of the terminals and ensures a good working environment. | |||||
| Door Opening | Axial 180° side-opening door. Equipped with an elastic lock on the side for effective latching. The lock's elasticity accommodates refractory expansion, allowing for free thermal expansion/contraction of the refractory material and ensuring an effective seal. | |||||
| Refractory & Insulation | Vacuum-formed high-purity lightweight alumina composite lining. Features high service temperature, low heat storage, excellent resistance to thermal shock (no cracking, no spalling), and superior insulation properties. | |||||
| External Shell Temperature | < 45°C | |||||
| Safety Protection | Integrated modular control unit with dual-loop control and protection. Includes: Overshoot, Overrun, Undershoot, Thermocouple Break, Phase Loss, Overvoltage, Overcurrent, Overtemperature, Current Feedback, and Soft Start protection. | |||||
| Power Cut on Door Open | Safety interlock: The main heating circuit is automatically disconnected when the door is opened during high-temperature operation, significantly reducing the risk of electric shock during material handling. | |||||
| Safety Temperature Control | Closed-loop thyristor (SCR) module trigger control (phase-shift or zero-crossing). Output voltage, current, and power are continuously adjustable with constant voltage, current, or power operation. Dual-loop regulation (inner current loop + outer voltage loop): Limits output current to the rated range during sudden load changes or overcurrent conditions, protecting heating elements from excessive current/voltage surges and ensuring safe, reliable, and precise control. | |||||
| Temperature Profile Setting | Intelligent temperature controller with multiple control modes: standard PID, AI adjustment (APID), or MPT. Features self-tuning/self-learning with no overshoot/undershoot. 30-segment program control for any heating/cooling slope. Supports commands like jump (loop), run, pause, stop, and allows on-the-fly program modification. AI algorithm with curve-fitting ensures smooth profile control. | |||||
| Profile Segments | 50-segment program control. Supports: 1 curve (50 seg.), 2 curves (28 seg. each), 3 curves (15 seg. each), 5 curves (9 seg. each). Multiple curves can be stored and recalled as needed. | |||||
| Front Panel Buttons | Two buttons/knobs: Main Power On/Off, Heating Chamber On/Off. | |||||
| Standard Accessories | One pair of crucible tongs, one pair of high-temperature gloves, one furnace floor plate. | |||||
