Description
High-Temperature Vacuum Atmosphere Furnace with In-Furnace Fan Stirring
This Vacuum Furnace is specifically designed for high-temperature atmosphere-protected sintering, heat treatment, and material testing processes. The equipment integrates a vacuum system, atmosphere system, hot air circulation stirring system, and intelligent temperature control system. The furnace chamber is equipped with a high-temperature fan stirring structure, which effectively improves the uniformity of the temperature field within the furnace. It is particularly suitable for powder materials, electronic materials, ceramic materials, and metal heat treatment processes where high temperature consistency is required.
The equipment adopts a five-sided heating structure, high-purity alumina lightweight insulation material, and a double-layer air-cooled furnace body design. It features stable heating, uniform temperature, strong vacuum atmosphere compatibility, and comprehensive safety protection, and is widely used in research institutes, university laboratories, and industrial production.
Product Features (Vacuum Furnace)
- Large-capacity furnace chamber, five-sided heating
This vacuum atmosphere furnace has a furnace chamber size of 600×600×900mm (depth×width×height) and adopts a five-sided heating design (heating elements are evenly distributed around the furnace chamber’s perimeter and bottom).
- Hot air stirring system, uniform temperature
The furnace chamber is equipped with 310S stainless steel fan blades at the top. These blades rotate and stir the internal space of the furnace, effectively eliminating temperature stratification. The stirring motor is water-cooled, with stepless speed regulation via a frequency converter, and a power of 3KW, ensuring uniform temperature distribution within the furnace.
- Forced cooling system, improved efficiency
The furnace chamber is equipped with stainless steel cooling coils, which can be filled with circulating cooling water to accelerate heat dissipation within the furnace. The circulating cooling water system is a closed-loop system, composed of a closed-loop water chiller (3P), control valves, and stainless steel piping. Cooling rate ≥35℃/h, meeting the requirement of reducing furnace temperature to 70℃ within 10 hours for furnace door opening, significantly improving equipment utilization.
- Vacuum and Multi-Atmosphere Compatibility
Utilizes a two-stage rotary vane vacuum pump (70L/s), achieving a vacuum level of -0.1MPa. The furnace lining steel plate is 6-20mm thick, double-sided welded, and can withstand a positive pressure of 0.1MPa. It can accommodate various gases such as hydrogen, nitrogen, argon, carbon monoxide, and oxygen, meeting the requirements of various processes including vacuum sintering, atmosphere protection, and reduction treatment.
- Pneumatic Locking Furnace Door, Side-Opening Design
The furnace door opens from the side and uses a pneumatic locking mechanism for reliable sealing. An observation window is provided on the furnace door for real-time monitoring of the furnace interior.
- 7-inch Touchscreen Paperless Recorder
Equipped with a 7-inch touchscreen paperless recorder, enabling functions such as temperature curve setting, historical data recording, and real-time monitoring.
