| - 1600℃, 1700℃: Silicon molybdenum rods | |
| Furnace Body | Processed by CNC machine tools, with processes including polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It features a two-color design, novel and attractive appearance, and advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Body Structure | The electric furnace body adopts an air-cooled double-layer structure. Effective air-cooled guide partitions enable overall cold air circulation in the furnace shell, which finally cools the heating element conductive plates before being discharged, avoiding high-temperature oxidation of the conductive plates and ensuring a good working environment. |
| Furnace Door Opening Method | The furnace door and chamber are integrally designed, with an electric upward opening (controllable opening height) and a locking device; the loading platform is electrically operated, driven by a motor-driven reducer for in/out movement, equipped with limit switches. |
| Cooperation Between Furnace Mouth and Loading Platform Refractories | The furnace mouth and loading platform refractories adopt a stepped cross-sealing design, with angles on both upper and lower parts of the refractories. The opening angle of the loading platform increases, and gradually decreases as the platform closes. |
| Loading Platform Capacity | Customer-defined, ranging from 100Kg to 10 tons |
| Loading Platform Movement | Electric mechanical |
| Refractory Materials | The furnace lining uses vacuum-formed high-purity alumina fiber lightweight plates. Positions prone to collision during material handling (furnace mouth, furnace bottom) use lightweight hollow spherical alumina plates, featuring high operating temperature, low heat storage, resistance to rapid heating/cooling, no cracking, no slag dropping, and good thermal insulation performance (energy-saving effect is over 80% compared to old-fashioned electric furnaces). |
| Insulation Materials | Three-layer insulation: high-alumina cotton, alumina blanket, and alumina fiberboard, with an energy-saving effect over 80% compared to old-fashioned electric furnaces. |
| Furnace Body Surface Temperature | ≤45℃ during long-term continuous operation |
| Protection | Adopts an integrated module control unit with accurate control precision, designed with dual-loop control and dual-loop protection, featuring overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start protection. |
| Control | Uses closed-loop thyristor module trigger control (phase-shift trigger mode). Output voltage, current, or power is continuously adjustable with constant voltage, current, or power characteristics. The current loop is the inner loop and the voltage loop is the outer loop. When the load is suddenly applied or exceeds the current limit, the output current of the voltage regulator is limited within the rated range to ensure normal operation of the output and regulator. The voltage loop also participates in regulation to maintain stable output current and voltage within the rated range, thus protecting heating elements from excessive current/voltage impact and ensuring safe, reliable control and precision.

| Dual Temperature Control | Temperature control around the furnace + bottom temperature control |
| Display Parameters | Temperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
| Buttons | Imported buttons with a service life of over 100,000 times, equipped with LED indicators |
| Temperature Curve Setting | Uses an intelligent temperature controller with multiple regulation modes (standard PID, artificial intelligence adjustment APID, MPT, etc.), featuring self-tuning and self-learning functions, no overshoot/undershoot, and 30-segment program control. It supports arbitrary slope heating/cooling control, with programmable commands (jump/cycle, run, pause, stop) and allows in-operation program modification. Adopts an AI adjustment algorithm with curve fitting function for smooth curve control. (See electric furnace video for details) |
| Multiple Curve Input | 30-segment program control function (50-segment customizable). Settings can be input as follows: one curve with 30 (50) segments, two curves with 14 (28) segments each, three curves with 9 (15) segments each, five curves with 5 (9) segments each. Multiple curves can be input simultaneously and called arbitrarily during use. |
| Communication Interface | Equipped with an RS485 communication interface with a maximum communication distance of 1000 meters. It allows computer control of furnace operations, including start, pause, stop, heating curve setting/reading, and parameter adjustment, with high reliability and ease of use. The computer interface displays rich content, including measured values, set values, output values, segment time, segment number, heating curves, and power percentage curves. Heating curves can be stored on the computer, with stored curves editable for set values and common parameters. Historical curves and reports can be filtered by time interval (1s-1h) and saved long-term. (See computer control software for details) |
