| Number of Loading Platforms | 1 |
| Power Supply (AC) | Three-phase five-wire 380V |
| Maximum Operating Temperature | 1650℃ |
| Long-term Operating Temperature | 1600℃ |
| Control Range | 80 to 1650℃ |
| Temperature Measuring Element | Platinum-rhodium thermocouple (Type B), measuring range 0-1820℃ |

| Furnace Temperature Uniformity | ±1℃ (depending on the size of the furnace chamber) |
| Heating Rate | Freely adjustable, with a range of 40℃/min (fastest) to 1℃/h (slowest) |
| Heating Elements | U-shaped 1800 silicon molybdenum rods. Silicon molybdenum rods are resistance heating elements based on molybdenum disilicide, with a maximum surface temperature of 1860℃. When used at high temperatures in an oxidizing atmosphere, a bright and dense glass film forms on the surface, which protects the rods from further oxidation. Thus, silicon molybdenum rod elements have unique high-temperature oxidation resistance. Under normal operation, the element resistance generally does not change with usage time, so new and old components can be mixed. |
| 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, with advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. Export quality with mirror baking paint. |
| Furnace Body Structure | The electric furnace body adopts an internationally advanced 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. |
| Loading Platform In/Out Mode | The loading platform and furnace chamber are of split design; the in/out and lifting of the loading platform are controlled by PLC, with centralized control via a touchscreen. |
| Loading Platform Braking Mode | The in/out and lifting of the loading platform use photoelectric isolation switch sensing signals, processed by PLC, with control commands issued via the touchscreen. |
| Loading Platform In/Out | Using stepless reduction motor with lead screw and guide, speed adjustable. |
| Loading Platform Lifting | Hydraulic lifting |
| 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 | 1000KG (customizable according to customer requirements) |
| Refractory Materials | The furnace lining uses imported vacuum-formed high-purity alumina fiber lightweight plates. Positions prone to collision during material handling (furnace bottom) use high-purity 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 fiberboard, imported fiberboard, with an energy-saving effect over 80% compared to old-fashioned electric furnaces. The easily-collided position at the furnace mouth uses lightweight special-shaped high-purity alumina materials. |
| Furnace Body Surface Temperature | ≤45℃ during long-term (20 days) 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. |
| 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 |
| Multiple Curve Input | 30-segment program control function. Settings can be input as follows: one curve with 30 segments, two curves with 14 segments each, three curves with 9 segments each, five curves with 5 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 centralized control of furnace operations via a touchscreen, 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. |

| Notes | 1. To avoid affecting the service life of the electric furnace, we recommend a maximum heating and cooling rate of 10-20℃/min (excessively fast heating will shorten the service life of heating elements). 2. This electric furnace has no vacuum-sealed structure, so flammable and explosive gases must not be introduced. 3. After using this electric furnace for a period of time, tiny cracks may appear in the furnace chamber, which is a normal phenomenon and will not affect use. It can be repaired with an alumina coating. 4. Introducing corrosive gases is not recommended. If strong corrosive gases such as S or Na need to be introduced, please inform us in advance, and we will specially treat the furnace chamber. 5. Do not allow high-temperature solutions to leak onto the furnace bottom. To avoid this, use a backing plate or alumina powder for isolation. 6. The instrument should be placed in a well-ventilated and dry place. |
