This equipment employs an intelligent PID programmable temperature control system, supporting 50-segment program control, automatic intake and exhaust regulation, and rapid cooling control, making it an ideal device for high-end atmosphere sintering and materials research.
Product Features（ Box Furnace）
- Uniform Temperature Distribution with Top and Bottom Plane Heating
Heating elements are embedded in the furnace bottom and top planes, arranged vertically and protected by ceramic sheaths, forming a bidirectional heating field. Compared to traditional side heating methods,
- Flat Top Structure Design with Strong Load-Bearing Capacity
The furnace top adopts a flat top structure, using beams and support plates made of reaction-sintered silicon carbide material, offering excellent temperature resistance. The furnace top insulation structure consists of ≥2 layers of fiberboard resistant to 1400℃, ≥1 layer of cotton board resistant to 1260℃, and ≥1 layer of cotton board resistant to 1000℃.
- Bottom Air Inlet with Six Uniformly Distributed Paths
Nitrogen gas is injected from the bottom of the furnace body, with a flow meter installed at the bottom. There is one air inlet equipped with a flow meter and valve. The air flow rate can be set by time period on the touchscreen, and the flow rate and pressure are displayed and recorded in real time.
- L-Shaped Exhaust with Anti-Backflow Design
There is one exhaust port (with a regulating valve), using an L-shaped bend exhaust hole. The exhaust pipe is made of SUS304 stainless steel, with a ceramic tube lined the exhaust pipe connected to the furnace body. The exhaust branch pipes and main exhaust pipes use a horn-shaped exhaust system. A temperature sensor is installed on the main exhaust pipe, and the temperature is displayed in real-time on the touchscreen. A manually controlled ceramic slide valve is installed on the exhaust pipe for easy operation.
- Multi-point monitoring for safety and reliability
The rear of the furnace body is equipped with an atmosphere test port, a furnace pressure monitoring port (equipped with a furnace pressure gauge for real-time monitoring of the furnace pressure), and an online temperature measuring thermocouple.
