| Furnace Structure and Material | Uniform Specification: The electric furnace body adopts an air-cooled double-layer carbon steel structure. Effective air-cooled guide partitions realize overall cold air circulation of the furnace shell, which finally cools the heating element conductive sheets before exhausting. This avoids high-temperature oxidation of the conductive sheets and ensures a good working environment. | |||||
| Furnace Door Opening Mode | Uniform Specification: Axial 180° side opening + 360° rotation. The furnace door lock is located on the side of the door, equipped with an elastic lock for effective locking. The elasticity of the lock absorbs the expansion of refractory materials, ensuring free thermal expansion and contraction of refractory materials and effective sealing. | |||||
| Refractory Insulation Material | Uniform Basic Specification: Furnace lining made of vacuum-formed high-purity lightweight alumina material (high operating temperature, low heat storage, resistance to rapid heating/cooling, no cracking, no slag falling, excellent thermal insulation) | 2100-Type Zirconia Fiber | ||||
| Furnace Shell Temperature | ≤45℃ | |||||
| Safety Protection | Uniform Specification: Adopts an integrated module control unit with accurate control precision, designed with dual-loop control and dual-loop protection. It provides protection against overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start. | |||||
| Multi-Point Temperature Control | Uniform Specification: Equipped with a function to cut off the main heating circuit when the furnace door is opened at high temperature during operation, greatly reducing the risk of electric shock when taking materials at high temperature. | |||||
| Safe Temperature Control | Uniform Specification: Uses closed-loop thyristor module trigger control (phase-shift trigger or zero-crossing trigger mode). Output voltage, current, or power is continuously adjustable, with constant voltage, constant current, or constant power characteristics. The current loop serves as the inner loop and the voltage loop as the outer loop. When a load is suddenly applied or the load current exceeds the limit, the output current of the voltage regulator is restricted within the rated current 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 current range (with sufficient adjustment margin), thereby protecting heating elements from excessive current/voltage impact and ensuring safe, reliable control and precision. | |||||
| Temperature Curve Setting | Uniform Specification: Uses an intelligent temperature controller supporting multiple regulation modes such as standard PID, artificial intelligence adjustment (APID), and MPT. It has self-tuning and self-learning functions, with excellent control performance of no overshoot and no undershoot. Equipped with a 50-segment program control function, it enables heating and cooling control at any slope, and supports programmable/operable commands such as jump (cycle), run, pause, and stop. It also allows program modification during operation. An artificial intelligence adjustment algorithm with curve fitting function is adopted to achieve smooth and stable curve control. | |||||
| Number of Heating Curve Segments | Uniform Specification: 50-segment program control function, which can be set as follows: 1 curve with 50 segments, 2 curves with 28 segments each, 3 curves with 15 segments each, 5 curves with 9 segments each; multiple curves can be input simultaneously and called arbitrarily during use. | |||||
| Panel Buttons | Uniform Specification: Two buttons/knobs: Main Power Button/Knob, Heating Chamber On Button/Knob. | |||||
| Spare Parts | Uniform Specification: 1 crucible tong, 1 pair of high-temperature gloves. | |||||
