Description
1700℃ Digital Lifting High-Temperature Stirring Furnace
The digital lifting high-temperature stirring furnace is a laboratory high-temperature equipment integrating high-temperature sintering, melting, reaction, stirring, and automatic lifting. It is specifically designed for universities, research institutes, new materials research and development, and industrial experiments. The equipment uses imported German high-purity alumina fiber lining, 1800-type silicon molybdenum rod heating elements, and an intelligent PID program temperature control system. The maximum operating temperature can reach 1700℃, with a long-term stable operating temperature of 1650℃.
This equipment adopts a bottom-opening electric lifting structure, with automatic lifting of the loading platform. It is equipped with a high-temperature ceramic stirring system on the furnace top, enabling forward and reverse rotation and up-and-down reciprocating stirring to ensure uniform melt composition. An optional infrared monitoring system allows for real-time observation of the melt state inside the furnace, significantly improving experimental safety and operational efficiency. It is an ideal device for high-temperature melting, ceramic sintering, glass melting, and high-temperature materials research.
Product Features
- High-Temperature Stirring Device for Excellent Melt Uniformity
Utilizing a furnace top-mounted insertion stirring structure, the high-temperature ceramic stirring rod is driven by a variable frequency motor, with a continuously adjustable stirring speed of 0-30 r/min. The stirring shaft can rotate clockwise and counterclockwise in both directions and simultaneously move up and down by ±5 cm during stirring. This effectively ensures the temperature and composition uniformity of the high-temperature melt, making it particularly suitable for smelting and alloying processes.
- Infrared Monitoring Function for Real-Time Furnace Monitoring
Equipped with an infrared camera, it enables real-time monitoring of the furnace temperature distribution and melt state. Operators can visually observe the material state and melt flow within the furnace through a multimedia display terminal, allowing them to monitor the process progress without opening the furnace.
- Bottom-Opening Door with Vertical Lifting and Fully Automatic Electric Control
Equipped with a bottom-opening door structure, the charging platform features fully automatic electric lifting and lowering with adjustable lifting time. The firing time is adjustable (1-9999S) after the charging platform rises and (1-9999S) after it descends, achieving fully automatic linkage control between lifting and firing. 4. Loading Platform Load Capacity: 1-50KG (Customizable).
- RS485 Remote Control, 50-Segment Programmable Temperature Control
Features 50-segment programmable temperature control, allowing input and setting of multiple temperature curves that can be recalled at will. The RS485 communication interface has a communication distance of up to 1000 meters. The furnace can be centrally controlled via a touchscreen, including start-up, pause, stop, temperature curve setting, reading, and parameter setting.
- Stepped Cross-Sealing, Four-Layer Insulation Structure
The furnace opening and charging platform refractory materials are fitted with a stepped cross-sealing system. The refractory materials have angles at both the top and bottom, increasing the opening angle of the charging platform and gradually decreasing it as it closes, forming a self-locking seal. The insulation material uses a four-layer structure (alumina fiber cotton, alumina fiberboard, alumina polycrystalline fiberboard, and vacuum-formed high-purity alumina fiber lightweight board), improving energy efficiency by over 80% compared to older electric furnaces.
