1700°C Mini Lift Furnace for Laboratory and Material Research
PRODUCT PARAMETERS
Description
1700℃ Small Electric Lift Furnace
The small lift furnace (with operating platform) is a compact, high-performance furnace designed specifically for high-temperature materials research and small-batch sintering. The equipment features a bottom-opening lifting structure and an integrated operating platform, facilitating sample loading and unloading and high-temperature material handling, making it particularly suitable for laboratory and pilot-scale production environments.
The furnace body utilizes a 1700-type silicon molybdenum rod with a vertical heating structure on all four sides, combined with a multi-layer composite insulation system and a double-layer air-cooled furnace shell design, achieving stable high-temperature operation and energy savings. The equipment has a maximum operating temperature of 1700℃ and a long-term operating temperature of up to 1550℃, with a high-precision temperature control capability of ±1℃ and a furnace temperature uniformity control capability of ±5℃.
Product Features
- Bottom-Opening Door with Vertical Lifting: Convenient and Safe Loading
Utilizing a bottom-opening door structure, the loading platform rises and falls to load and unload materials. The lifting speed is adjustable from 5-30 seconds. The loading platform is made of alumina ceramic fiber material, offering high temperature resistance, excellent thermal insulation, and a load capacity of 50kg. The bottom-opening door design facilitates sample loading and unloading from the bottom, making it particularly suitable for the heat treatment of precision ceramics and small workpieces.
- Stepped Cross-Sealing: Excellent Sealing Performance
The furnace opening and the loading platform refractory material are fitted with a stepped cross-sealing system. The refractory material has angles at both the top and bottom. The angle increases when the loading platform opens and gradually decreases as it closes, forming a self-locking seal. This effectively prevents heat leakage and improves thermal efficiency.
- 1700℃ Ultra-High Temperature Performance with Type B Thermocouple Temperature Control
The maximum temperature reaches 1700℃. It uses U-shaped 1800 silicon molybdenum heating elements, vertically installed around the furnace chamber. The Type B thermocouple temperature measurement range is 0-1820℃, with a temperature control accuracy of ±1℃ and a furnace temperature uniformity of ±5℃.
- Four-layer insulation structure, energy saving of over 80%
The insulation material adopts a four-layer structure: alumina fiber cotton, alumina fiber board, alumina polycrystalline fiber board, and vacuum-formed high-purity alumina fiber lightweight board material. This results in energy savings of over 80% compared to older electric furnaces. The furnace shell temperature remains below 45℃ during long-term, uninterrupted operation.
