The Eyes Inside the Furnace: Capabilities and Expansion of Process Monitoring in Graphitization FurnacesMar 18, 2026

I. Standard Configuration: Comprehensive Pressure and Flow Monitoring

  • Real-Time Monitoring and Recording:The system can monitor and record the furnace pressure change curve (absolute or relative pressure) in real time at high frequency. Additionally, the set flow rate and actual flow rate of the inlet gas and mass flow controller (MFC) are recorded throughout the process. These are standard functions.

II. Advanced Option: Gas Composition Analysis

  • Technical Support:Real-time monitoring of gas composition (such as O2, H2, CO, CH4, etc.) is completely achievable, but this is an advanced optional function, not a standard configuration.

  • Implementation Method:Requires integrating additional gas analysis systems for the customer, such as:

    • Gas Chromatograph (GC):High analysis precision but longer cycle time.

    • Oxygen Analyzer, Dew Point Meter:Used for专项 monitoring of specific components.

  • Mass Spectrometer (MS):Fast response speed, capable of analyzing multiple gas components with high precision, ideal for high-end scientific research and strict quality control.

  • Integration Solution:We reserve sampling interfaces and connect the analyzer's signal to the main control system, enabling同步 display and recording of composition data alongside temperature and pressure curves.

III. Application Value

  • Process Development:Precisely understand the decomposition and reaction products of materials at different temperatures, aiding new process development.

  • Quality Warning:By monitoring concentration changes of characteristic gases such as CO and CH4, the graphitization process can be assessed, and even the endpoint can be determined.

  • Safety Assurance:Real-time monitoring of O2 concentration ensures process safety.
