| Temperature Control Precision | ±1℃ (integrated circuit control, no overshoot) |
| Furnace Temperature Uniformity | ±5℃ |
| Hot Air Agitation | Function: A fan blade is installed at the top of the furnace chamber. Its rotation agitates the internal air to achieve uniform temperature distribution. The rotational speed is infinitely variable via a frequency converter. |
| Agitation Blades | 310S stainless steel |
| Refrigeration Unit | 2P water chiller |
| Furnace Door Opening Method | Pneumatic lifting and locking; switch controls the opening and closing height. The furnace body is fully sealed. |
| Temperature Control System | Equipped with a 10-inch touchscreen for integrated control. The temperature controller is a high-precision 0.1-class device with 50-segment temperature control. The touchscreen can store 15 sintering curves. PLC: Siemens (international first-class brand); Power Regulator: Integrated type (Sichuan Yingjie), supporting multiple control modes such as constant current, constant voltage, and constant power, with communication functions for voltage, current, and power. |
| Adopts an integrated module control unit with accurate precision, designed with dual-loop control and protection (against overshoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, soft start, etc.). | |
| Equipped with a timing function, with audible and visual alarm when time is up. | |
| Heating Rate | Freely adjustable, range: 20℃/min (fastest) to 1℃/h (slowest) |
| Oxygen Content Analyzer | Equipped with an imported zirconia probe, measuring range: 10ppm-21%, with alarm for excessive oxygen content |
| Exhaust Port | Top-mounted DN30 exhaust port with an adjustable valve |
| Gas Inlets | 8 uniform inlets distributed at the lower part of the left and right sides of the furnace chamber, integrated into one main inlet with a flow meter |
| Furnace Bottom Plate | 310S heat-resistant stainless steel plate, bottom height: 920mm |
| Insulation Materials | Three-layer insulation: 1600-type GM30 foam ceramic bricks, 1400-type polycrystalline alumina fiberboard, 1260-type fiber blanket. Energy-saving effect is over 80% higher than that of old-fashioned electric furnaces. |
| Furnace Body | Fully sealed, processed by polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It has a novel and attractive appearance, with advantages of oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Body Surface Temperature | ≤ Room temperature + 20℃ during long-term continuous operation |
| Random Spare Parts | 1 crucible tong, 1 pair of high-temperature gloves |
| 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, we recommend the maximum heating and cooling rate be ≤20℃/min (excessively fast heating will shorten the service life of heating elements). |
| 2. This box-type furnace has no vacuum sealing structure and must not be filled with flammable and explosive gases. | |
| 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. Do not allow high-temperature solutions to leak 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 area. | |
| Packing List | 1 electric furnace, 1 crucible tong, 1 pair of high-temperature gloves, 1 instruction manual, 1 certificate of conformity, 1 acceptance report (factory inspection report), 1 sales delivery note. |
| 1. The electric furnace is packaged in two layers: wrapped with sponge paper, then plastic film, and fixed with an iron frame base. | |
| 2. Free door-to-door delivery within urban areas in China. | |
| 3. We are responsible for any damage to the electric furnace during transportation. |
