High-temperature laboratory furnaces operate at temperatures above 1300°C and are specially designed for laboratories, industrial and mining enterprises, and research institutions. They are used for elemental analysis, as well as for heating small steel components for quenching, annealing, tempering, and processing electronic ceramics and other new materials.
The complete system includes a temperature controller, thermocouples, and a closed-type trigger. Temperature control can be relay-based or thyristor-based. Since these are intermittent-operation furnaces, they generally use 40-segment PID programmable controllers to strictly control the firing or heating process. The furnace automatically cuts power when the door is opened to maximize safety.
Optional Features:
- Real-time temperature recording, printing, and digital communication interfaces.
- Exhaust system for minor waste gas emission, suitable for various materials.
The electrical components are integrated into the furnace body for compactness. The temperature control panel is mounted on the side for easy observation and adjustment. The PID controller can automatically track optimal PID values and allows arbitrary setting of measurement parameters. Compensation functions ensure the furnace chamber temperature matches the display. Temperature control uses soft start/stop and thyristor phase-shift regulation, with adjustable output from 0–98%. All switches and meters are clearly labeled in Chinese.
Application Range:
- Thermal Processing, Cement, and Building Materials: Heat treatment of small workpieces.
- Pharmaceutical Industry: Testing of medicines, pre-treatment of medical samples.
- Analytical Chemistry: Sample preparation for water quality analysis, environmental analysis, petroleum analysis, etc.
- Coal Analysis: Determining moisture, ash, volatile content, ash melting point, elemental composition; can also serve as a general-purpose ashing furnace.
