This high-temperature graphitization furnace is a new type of furnace developed from the original medium frequency high-temperature furnace and has already been launched in the market. It is specifically designed as processing equipment for the carbonization and graphitization of graphene/polyimide composite films. It has received positive customer feedback for its accurate temperature control, stable equipment performance, simple operation, 15-25% lower power consumption per square meter compared to similar equipment on the market, as well as strong insulation and corrosion resistance.
Maximum Operating Temperature: 3000°C, Typical Operating Temperature: 2500°C

6. Temperature Control: Program control and manual control; Temperature Control Accuracy: ±1°C
-
1.High degree of equipment automation. All switching components and all operating parameters are stored digitally in the PLC database, with a reserved communication interface for customer connection.
-
2.Ultra-high temperature furnace body up to 3000°C, meeting the carbonization and graphitization requirements of graphene/polyimide composite films.
-
3.Uses a digital intelligent temperature control system, fully automatic high-precision completion of temperature measurement and control. The system can heat up according to a given heating curve and can store up to twenty different process heating curves (totaling 400 segments).
-
4.The interior of the furnace body and all piping are treated with insulation and high-strength anti-corrosion treatment to accommodate the volatile deposition characteristics generated during thermal cracking in the carbonization and graphitization process of graphene/polyimide composite films.
-
5.Adopts an internal circulating pure water cooling system; digital flow monitoring system; furnace switching uses high-performance medium frequency contactors; comprehensive PLC automatic control and protection system for water, electricity, and gas.
-
6.The unique induction coil undergoes 5 layers of insulation treatment, completely solving the application problems of induction coils or the need for high-temperature insulation, ensuring that the coil maintains good insulation performance even when the corundum material ages or cracks. It effectively prevents coil arcing, current leakage, and other phenomena.
