describe
The 1200°C top-opening electric precision furnace offers accurate temperature control, rapid heating, and reliable performance for laboratory and industrial heat treatment applications.
Product Features
Operating temperature
- The 1200°C top-opening electric precision furnace offers a maximum operating temperature of 1200°C and stable long-term operation at 1150°C. It features precise digital temperature control, uniform heating, and rapid ramp-up and cooling rates.
- High-quality resistance heating elements and advanced multi-layer insulation ensure energy efficiency, reliable performance, and long service life. The top-opening design allows easy loading and unloading, while safety features protect operators and equipment. Ideal for laboratories and industrial applications requiring accurate, high-temperature heat treatment, sintering, and material testing.
Refractory materials
- The furnace lining uses vacuum-formed high-purity alumina lightweight material, with hollow spherical alumina plates at load-bearing and high-wear areas like the furnace bottom and opening. This design ensures high-temperature tolerance, low heat storage, and excellent resistance to rapid heating and cooling. It prevents cracking and slag shedding while providing superior heat retention. With energy savings exceeding 80% compared to traditional electric furnaces, it delivers efficient, reliable, and durable performance for industrial and laboratory high-temperature applications
control
- The system utilizes advanced closed-loop technology with thyristor module trigger control, supporting phase-shift and zero-crossing triggering for precise, continuous adjustment of voltage, current, and power. It delivers stable constant voltage, constant current, or constant power output, ensuring highly accurate thermal management for industrial and laboratory applications.
- A dual-loop structure, with the current loop as the inner control and the voltage loop as the outer control, provides rapid response to sudden load changes. When the load exceeds the rated current, the output is automatically limited within safe ranges, protecting both the voltage regulator and heating elements from surges.
- This intelligent regulation ensures safe, reliable, and efficient operation while maintaining sufficient adjustment margin for consistent performance. It enhances heating precision, reduces equipment stress, and extends component lifespan, making it ideal for high-temperature processes requiring stable and accurate control.
Temperature profile setting
- The furnace features an intelligent temperature controller with multiple modes, including standard PID, AI-based APID, and MPT, offering self-tuning and self-learning capabilities. It provides precise 30-segment programmable control, enabling customized temperature rise and fall with adjustable slopes. Operators can use commands like jump (loop), run, pause, and stop, and modify programs anytime during operation. An AI-based curve-fitting algorithm ensures smooth, uniform temperature control without overshoot or undershoot, delivering reliable, accurate, and efficient performance for high-temperature industrial and laboratory applications.
