Product Features

Furnace body structure

• The electric furnace body adopts a double-layer air-cooled structure designed to improve heat dissipation and enhance the reliability of high-temperature operation. The specially designed air-cooling guide baffles create an efficient airflow path within the furnace shell, allowing cool air to circulate through the double-layer structure and continuously remove accumulated heat.
• During operation, the cooling airflow passes around the conductive plates of the heating elements before being discharged from the furnace body. This effectively reduces the temperature of the conductive plates and helps prevent oxidation caused by prolonged exposure to high temperatures. By protecting the conductive components, the air-cooling system helps extend their service life and maintain stable heating performance.
• The double-layer structure also reduces heat accumulation around the furnace body, helping maintain a more comfortable working environment. This optimized cooling design provides effective thermal management, reliable component protection, and stable operation for laboratory material processing applications.

Refractory materials

• The furnace lining is constructed from vacuum-formed lightweight alumina material, providing excellent thermal insulation and reliable performance under high-temperature operating conditions. The lightweight structure reduces heat storage, allowing the furnace to heat up and cool down efficiently while improving overall energy performance.
• Areas subject to frequent material handling, including the furnace opening and bottom, are reinforced with lightweight hollow alumina plates. These components provide enhanced structural stability and resistance to mechanical impact during loading and unloading operations.
• The alumina lining offers excellent resistance to rapid heating and cooling, helping minimize thermal stress and reducing the risk of cracking during repeated temperature cycles. It also provides good resistance to slag shedding, helping maintain a clean furnace chamber and reduce contamination of processed materials.
• With low heat storage, high-temperature resistance, and efficient insulation performance, the lining supports stable temperature control, faster thermal response, and reliable long-term operation for laboratory material processing applications.

control

• The furnace uses closed-loop thyristor module control technology to provide precise and stable regulation of heating power. Phase-shift or zero-crossing triggering can be selected according to process requirements, enabling continuous adjustment of output voltage, current, or power.
• The control system adopts a dual-loop architecture, with the current loop serving as the inner loop and the voltage loop as the outer loop. This configuration provides constant-current, constant-voltage, or constant-power operation while maintaining sufficient regulation capacity.
• When the load suddenly increases or the current exceeds the preset limit, the system automatically limits the regulator output to the rated current range. The voltage loop simultaneously participates in regulation to maintain stable output conditions.
• This coordinated control and protection mechanism helps prevent excessive current and voltage surges from reaching the heating elements. It improves power stability, protects critical components, and ensures safe, reliable, and precise furnace operation during long-term high-temperature processing.

Temperature profile setting

• The furnace is equipped with an intelligent temperature control system supporting multiple regulation modes, including standard PID, AI-based APID, and MPT. These control modes provide flexible temperature management for different thermal processing requirements.
• The controller features automatic tuning and self-learning functions, enabling the system to optimize control parameters and maintain stable temperature performance with minimal overshoot or undershoot. It supports 30-segment programmable temperature control, allowing users to define heating, holding, and cooling stages with adjustable ramp rates.
• Programmable commands include jump, loop, run, pause, and stop, while temperature programs and control parameters can be modified during operation. The integrated AI-based regulation algorithm uses curve-fitting technology to optimize the temperature profile and achieve smooth, continuous control curves.
• This intelligent control architecture improves temperature stability, process repeatability, and operating flexibility, making the furnace suitable for demanding laboratory material processing and high-temperature research applications.
