Key Features:

• Design and Structure: Our furnace features a circular, horizontal design with dual-opening doors and a single chamber structure. The high-temperature graphitization process is powered by medium-frequency induction heating. The furnace interior is equipped with a water-cooled induction coil, while an integrated graphite crucible serves as the induction current sensor surrounded by carbon felt as a thermal insulation material. The dual-layer water cooling system consists of a 304 stainless steel inner container and a cooling water jacket for temperature maintenance and safety.
• Operational Flexibility: The furnace is designed with a vacuum extraction interface, electrode flange, infrared temperature measurement ports, gas outlet, and an adjustable base height to accommodate different induction sensor requirements.
• User-Friendly Capabilities: The furnace cover operates using a manual hydraulic lift and swivel mechanism, offering more ergonomic handling compared to traditional manual wheel operations. Additionally, it is equipped with an observation port, temperature measurement port, and gas inlet to facilitate monitoring during operation.
• High-Quality Components: The induction coils are constructed with premium square copper tubing to minimize magnetic leakage while maximizing efficiency. Supporting arms for the sensors are made from stainless steel to prevent high-temperature degradation. Additionally, the resonant capacitors have a water-cooling structure with a 30% safety margin.
• Real-Time Temperature Monitoring: An imported infrared thermometer allows for real-time observation of the crucible temperature within the furnace. This advanced temperature sensing technology ensures accurate measurement even with smoke, dust, or particulate obstructions.
• Vacuum Acquisition System: The comprehensive vacuum system includes a direct-drive mechanical pump, electromagnetic vacuum valve for gas charging, vacuum butterfly valve, diaphragm valve, and connecting pipelines. It is equipped with a diaphragm vacuum valve for process gas charging and a second for reintroducing air before opening the furnace door.
• Intelligent Control System: The temperature control instrument employs a 0.1% class intelligent segmentation program to regulate heating cycles, with the capability to store up to 50 heating programs and optional communication ports. The system features PLC protection for monitoring conditions such as phase loss, water pressure, circuit status, protective gas levels, vacuum pump operation, furnace temperature, and control cabinet temperature. Moreover, it provides sequential control and interlocking protection for power, furnace body, cooling water, and protective gas systems. Alerts and alarms trigger for situations such as furnace body water temperatures exceeding 60 degrees, vacuum unit low-water conditions, and failure to achieve vacuum levels.
