| Category | Parameter |
|---|---|
| Furnace Body | CNC-machined, polished, sanded, acid-washed, phosphated, powder-coated, and high-temperature baked. Dual-color design, novel and aesthetically pleasing appearance. Features oxidation resistance, acid/alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Structure | Internationally advanced air-cooled double-layer furnace body. An effective air-cooled guide baffle ensures overall cold air circulation in the furnace shell, finally cooling the heating element conductive plates before exhausting out of the furnace. This avoids high-temperature oxidation of the conductive plates and ensures a good working environment. |
| Refractory Material | Furnace lining made of vacuum-formed high-purity alumina lightweight material. Locations prone to material contact (furnace mouth, furnace bottom) use lightweight hollow alumina balls. Features: high operating temperature, low heat storage, resistance to rapid heating/cooling, no cracking, no slagging, and good insulation performance (energy-saving effect is over 80% compared to old-style electric furnaces). |
| Insulation Material | Three-layer insulation: aluminum silicate fiberboard, alumina fiberboard, and alumina (polycrystalline) fiberboard. Energy-saving effect is over 80% compared to old-style electric furnaces. |
| Outer Shell Temperature | During long-term continuous operation, the outer shell temperature is less than 45°C. |
| Category | Parameter |
|---|---|
| Protection | Integrated modular control unit with accurate control precision. Designed with dual-loop control and dual-loop protection, featuring protection against overshoot, undershoot, thermocouple breakage, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start. |
| Control Cabinet | Comes with an independent standard control cabinet. A cable schedule for on-site equipment connection is provided (cables to be purchased by the buyer). |
| Control Method | Closed-loop technology with SCR module trigger control, phase-shift triggering or zero-crossing triggering. Output voltage, current, or power are continuously adjustable, with constant voltage, constant current, or constant power characteristics. The current loop is the inner loop, and the voltage loop is the outer loop. When a sudden load is applied or the load current exceeds the limit, the output current of the regulator is limited within the rated current range to ensure normal operation of the output and regulator. Meanwhile, the voltage loop also participates in regulation, maintaining constant output current and voltage under the premise of sufficient adjustment margin. This protects the heating elements from excessive current and voltage surges, achieving safe and reliable control and precision. |
| Display Parameters | Temperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc. Buttons are imported, with a lifespan exceeding 100,000 cycles, and come with LED indicators. |
| Temperature Curve Setting | Intelligent temperature controller, equipped with standard PID, artificial intelligence APID, or MPT adjustment modes. Features self-tuning and self-learning functions, with excellent control characteristics of no overshoot and no undershoot. Equipped with 30-segment program control function, enabling heating and cooling control at any slope. Supports programmable/operable commands such as jump (loop), run, pause, and stop, and allows program modification at any time during program-controlled operation. Uses an artificial intelligence adjustment algorithm with curve fitting capability to achieve smooth and flat curve control effects. Multiple curves can be input, 30 segments. |
