Silicon Carbide Vacuum Sintering Furnace

Applications: This equipment is suitable for vacuum sintering and atmosphere pressureless sintering of boron carbide, silicon carbide or other materials.
 

Main Features:
1to1 standard structure (one set of power supply, one set of furnace body)

Maximum operating temperature: 2350ºC, common temperature 2300ºC, common constant temperature zone size (600MM X600MMx 1600MM, 500mm x500mm X1300mm). The size can be customized according to customer's requirements.

Temperature uniformity: ≤±10ºC;
Temperature control method: automatic; manual; thermocouple temperature measurement from room temperature to 1200 degrees; high temperature measurement using imported infrared thermometer; low temperature and high temperature automatic switching.
Security: double protection with explosion-proof port and pressure relief valve, which is safe and reliable
Automation: One-button automatic replacement of atmosphere in the furnace; automatic detection of water and gas; automatic temperature control throughout the heating process

Control accuracy: ±5ºC
Cold ultimate vacuum: 3Pa
Working temperature: 2250ºC (argon gas atmosphere)
Design temperature: 2350ºC (argon gas atmosphere)
Heating rate: ≥10ºC/min (full load, atmosphere, below 1500ºC)
≥5ºC/min (full load, atmosphere, below 1800-2300ºC)





   Product advantages:
1.Fully automation with one-key replacement system (vacuum in the furnace; argon gas filling process), Automatic monitoring of water and electricity during the whole process of operation; Touch screen simulation can observe the operating status of the equipment at any time. The equipment alarm indication, heating curve, switch machine Operations all can be viewed and operated on the touch screen.

2. The materials are authentic and reliable. The furnace body is made of 304 stainless steel, which is built in strict accordance with the pressure vessel standard, and has good corrosion resistance and airtight performance. The insulation materials are made of high-purity graphite felt, which is durable. All electrical components are imported or domestic top brands with reliable operation.

3. The automatic explosion-proof valve is installed in the furnace body with high security and reliability; The sensor part is equipped with a flow switch separately to monitor the water flow in real time. The power supply sets over-current protection and over-voltage protection strictly and effectively as required.
