| Refractory Material | Furnace lining is made of vacuum-formed high-purity alumina fiber lightweight board; the furnace bottom (a position prone to collision during material handling) is made of high-purity lightweight hollow sphere alumina board. It features high operating temperature, low heat storage, resistance to rapid heating/cooling, no cracking, no slag falling, and excellent thermal insulation (energy-saving effect is more than 80% higher than old-fashioned electric furnaces). |
| Insulation Materials | Four-layer insulation structure: Alumina fiber cotton, alumina fiber board, polycrystalline alumina fiber board (imported materials). Energy-saving effect is more than 80% higher than old-fashioned electric furnaces. |
| Furnace Body Surface Temperature | ＜45℃ during long-term continuous operation |
| Safety Protection | Adopts an integrated module control unit with accurate control precision, designed with dual-loop control and dual-loop protection. It provides protection against overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start. |
| Temperature Control System | Uses closed-loop thyristor module trigger control (phase-shift trigger or zero-crossing trigger mode). Output voltage, current, or power is continuously adjustable, with constant voltage, constant current, or constant power characteristics. The current loop serves as the inner loop and the voltage loop as the outer loop. When a load is suddenly applied or the load current exceeds the limit, the output current of the voltage regulator is restricted within the rated range to ensure normal operation. The voltage loop also participates in regulation to maintain stable output current and voltage within the rated range (with sufficient adjustment margin), protecting heating elements from excessive current/voltage impact and ensuring safe, reliable control effect and precision. |
| Display Parameters | Temperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
| Buttons | Imported buttons with service life exceeding 100,000 times, equipped with LED indicators |
| Temperature Curve Setting | Uses an intelligent temperature controller supporting multiple regulation modes such as standard PID, artificial intelligence adjustment (APID), and MPT. It has self-tuning and self-learning functions, with no overshoot or undershoot. Equipped with a 30-segment program control function, it enables heating and cooling control at any slope, and supports programmable/operable commands such as jump (cycle), run, pause, and stop. Program modification is allowed during operation. An artificial intelligence adjustment algorithm with curve fitting function is adopted to achieve smooth and stable curve control. |
| Number of Heating Curve Segments | 50-segment program control function, which can be set as follows: 1 curve with 50 segments, 2 curves with 28 segments each, 3 curves with 15 segments each, 5 curves with 9 segments each; multiple curves can be input simultaneously and called arbitrarily during use. |

| Warranty Scope & Period | The electric furnace comes with a 1-year free warranty; heating elements are not covered (free replacement for natural damage within 3 months) |
| Notes | 1. To ensure the service life of the electric furnace, the recommended maximum heating and cooling rate is 10-20℃/min (excessively fast heating will shorten the service life of heating elements); |
| 2. This electric furnace has no vacuum sealing structure, and flammable and explosive gases are strictly prohibited; | |
| 3. Minor cracks may appear in the furnace chamber after long-term use, which is normal and does not affect operation. They can be repaired with alumina coating; | |
| 4. Introduction of corrosive gases is not recommended. If strong corrosive gases (such as S, Na) need to be used, please inform us in advance for special furnace chamber treatment; | |
| 5. High-temperature solutions are prohibited from leaking onto the furnace bottom. Use a base plate or alumina powder for isolation; | |
| 6. The equipment should be placed in a well-ventilated and dry environment. |
