Temperature Monitoring in Primary Metals Processing

High Precision Heat Treatment in Vacuum Carburizing

Vacuum Carburizing is the process of hardening certain metals or alloys to achieve a specific surface resistance. The furnace has the capability to introduce certain gasses like acetylene within the carburizing chamber. Further furnace processes include the gas quench (nitrogen or helium up to 20 Bar or 290PSI), which is used to cool down the products at a fast rate. The end-products are used principally in the automotive industry.

Application Need 

Monitoring the product heat treatment cycle for different chambers (heating, carburizing and quenching) and performing CQI-9 uniformity surveys is critical. Semi-continuous furnaces are not possible to monitor with a trailing thermocouple, so an internal profiling system is an advantage for regular surveys.

 

Benefits to the customer 
  • Verify the complete heat treatment cycle from heating to quench by monitoring product and ambient conditions
  • Conform to strict CQI-9 heat treatment specifications
  • For OEM use in the research and development of new vacuum carburizing solutions
  • Document traceability and produce thermal profiles for specific customers, proving product compliance with heat treat guidelines
Thermal Profiling Systems
  • Confirm furnace compliance to CQI-9 with a dedicated software and hardware package
  • Monitor the full product thermal profile, including soaking and pressure quench
  • Use as an R&D tool for OEMs in the design of new furnaces especially the quench design
