1000°C hot-air stirring box-type high-temperature furnace with heating elements on both sides and bottom. The top hot-air stirring system improves temperature uniformity to ±5°C, equipped with a 7-inch touch screen and 30-segment programmable temperature control.
| Category | 1000°C |
|---|---|
| Item | Specification / Description |
| Chamber Size | 800×500×500 mm (Depth×Width×Height) |
| Power Supply (AC) | 380V |
| Power | 24 kW (Approx. 15 kW at constant temperature) |
| Control Range | 80°C to 1200°C |
| Operating Temp. Range | 300°C to 1000°C |
| Touch Screen | 7-inch true-color touch screen with functions for temperature setting, recipe storage, historical curves, data reports, alarm information, etc. |
| Temperature Sensor | K-type thermocouple, measuring range 0–1320°C |
| Heating Element | High-temperature alloy resistance wire |
| Heating Element Position | Evenly distributed on both sides and the bottom of the chamber |
| Temp. Control Accuracy | ±1°C (Integrated circuit control, no overshoot) |
| Temp. Uniformity | Within ±5°C (depending on chamber size) |
| Hot Air Circulation | Fan blades installed at the top of the chamber stir the internal temperature to achieve uniform distribution. |
| Blade Material | 310S stainless steel, service temperature 1000°C |
| Circulation Motor & Speed | Air-cooled motor with variable frequency drive (VFD) for stepless speed control |
| Heating Rate | Adjustable: maximum 15°C/min, minimum 1°C/h |
| Furnace Body | CNC machined, finished by polishing, grinding, pickling, phosphating, powder coating, and high-temperature baking. Two-tone appearance, aesthetically pleasing, with advantages of oxidation resistance, acid/alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Structure | Air-cooled double-layer structure. Effective air-guiding baffles enable overall cold-air circulation, cooling the heating element terminals before exhausting, preventing terminal oxidation and ensuring a good working environment. |
| Door Opening | Axial 180° side-opening, rotatable 360° to prevent arm burns during high-temperature loading/unloading. Bottom-mounted stainless steel spring latch ensures secure locking. The spring's elasticity accommodates refractory expansion, allowing free thermal expansion/contraction and an effective seal. |
| Refractory Material | Vacuum-formed lightweight alumina composite lining. Impact-prone areas (door opening, hearth) use lightweight hollow-sphere alumina boards. Features high service temperature, low heat storage, excellent thermal shock resistance, and good insulation. |
| Insulation Material | Three-layer insulation: Aluminosilicate fiberboard, Alumina fiberboard, Polycrystalline alumina fiberboard. |
| External Shell Temp. | < 45°C during continuous long-term operation |
| Protection Functions | Integrated modular control unit with dual-loop control and protection. Includes protections against: overshoot, overrun, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft-start faults. |
| Control Method | Closed-loop thyristor (SCR) module phase-shift trigger control. Output voltage, current, and power are continuously adjustable with constant voltage, constant current, or constant power operation. Dual-loop regulation (inner current loop + outer voltage loop) limits output to the rated range during sudden load changes or overcurrent, protecting heating elements and maintaining stable output for safe, reliable, and precise control. |
| Display Parameters | Temperature, segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
| Pushbuttons | Imported pushbuttons with LED indicators, service life > 100,000 cycles |
| Temperature Profile | Intelligent 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. |
| Multi-Curve Program | 30-segment program supports: 1 curve (30 segments), 2 curves (14 seg. each), 3 curves (9 seg. each), 5 curves (5 seg. each). Multiple curves can be stored and recalled as needed. |
| Vent Outlets | 2 outlets, diameter φ8mm, located on left and right sides at the rear of the furnace |
| Standard Accessories | One set of alloy resistance wires, one pair of crucible tongs, one pair of high-temperature gloves |
| Important Notes | For optimal furnace and heating element lifespan, recommended heating and cooling rates are 10-20°C/min. (Faster rates may shorten element life).This box furnace is NOT vacuum sealed. DO NOT introduce flammable or explosive gases.Minor cracks may appear in the chamber lining after use. This is normal and does not affect performance. They can be repaired with an alumina coating.Introducing corrosive gases is not recommended. If strong corrosive gases (e.g., S, Na) must be used, please inform in advance for special chamber treatment.Avoid spilling high-temperature solutions onto the furnace floor. Use a protective plate or alumina powder for isolation.he instrument should be placed in a well-ventilated, dry area. |
