PRODUCT PARAMETERS
Description
1200°C High-Temperature Box-Type Resistance Furnace with Top Stirring Fan
The 1200°C high-temperature box-type resistance furnace (with top stirring fan) is an industrial-grade box-type electric furnace used for high-temperature heat treatment, material sintering, and experimental analysis. Based on a standard high-temperature box furnace, the addition of a top stirring fan enhances heat circulation and temperature uniformity within the furnace, resulting in a more stable internal thermal field. This makes it suitable for heat treatment processes and experimental scenarios requiring high temperature uniformity.
Box-Type Resistance Furnace Product Features
- Top-mounted stirring fan for superior furnace temperature uniformity
A stirring fan is installed at the top of the furnace to force-circulate hot air, eliminating temperature stratification and dead zones. Furnace temperature uniformity is ±5℃ (referring to HB5425-2012 standard, 5-point temperature measurement within the range of 300-1000℃, no-load measurement), meeting the stringent requirements for temperature uniformity in aerospace heat treatment specifications.
- Four-layer insulation structure for energy savings of over 80%
The furnace lining uses imported German MESCHUPP vacuum-formed high-purity alumina fiber lightweight board material. High-purity lightweight hollow spherical alumina boards are used in areas of the furnace bottom prone to material handling. The insulation material employs a four-layer structure: alumina fiber cotton, alumina fiber board, and alumina polycrystalline fiber board, all imported materials, resulting in energy savings of over 80% compared to older electric furnaces.
- Top Exhaust Port for Timely Removal of Fumes and Waste Gas
A manually operable exhaust port is located on the top of the furnace to promptly remove fumes and reaction waste gas generated during heat treatment, ensuring a clean furnace environment and protecting heating elements and samples from contamination.
- Air-Cooled Double-Layer Furnace Body with Outer Shell Temperature ≤45℃
The furnace body adopts an air-cooled double-layer structure. Even with continuous operation, the outer shell temperature remains below 45℃, ensuring safe operation and a comfortable working environment.
- Multiple Safety Protections
An integrated modular control unit is employed, featuring dual-loop control and dual-loop protection functions. It provides comprehensive protection against overshoot, over-adjustment, under-adjustment, thermocouple breakage, phase loss, over-pressure, over-current, over-temperature, current feedback, and soft start.
