Vacuum Graphitization Furnace
Performance characteristics
1. The equipment has a high degree of automation. All switch components and operating parameters of the equipment are stored in the PLC database in digital form, and a communication interface can be reserved for customer connection.
2. The ultra-high temperature furnace body within 3000℃ can meet the graphitization treatment of various carbon materials.
3. The digital display intelligent temperature control system is adopted to complete the temperature measurement and control process automatically and accurately. The system can heat up according to the given heating curve, and can store twenty different process heating curves with a total of 400 sections.
4. The problem of ablation and sinking of the crucible inside the horizontal graphitization furnace is completely solved. The actual production of 60 furnaces only sinks 5mm.
5. Adopt internal circulation pure water cooling system; digital flow monitoring system, furnace conversion adopts high-performance medium frequency contactor; comprehensive PLC water, electricity, gas automatic control and protection system
6. The unique induction coil adopts 5 times insulation treatment, which completely solves the application problems of induction coil or high temperature insulation, ensuring that the coil can still maintain good insulation performance under the condition of corundum aging and cracking, and can effectively prevent coil sparking, current leakage and other phenomena
The supporting systems of the complete set of equipment include: vacuum system, purification system, cooling system, exhaust gas treatment, DCS central control system
