Application: Vacuum Oxygen Decarburization (VOD)

Vacuum Oxygen Decarburization (VOD) is the manufacturing process by which the quality of stainless steel is assured.

To be carried out accurately, the process depends on the ability to measure the composition of the stream of gas leaving the furnace throughout the process.

Thyson Technology designs and builds sampling systems based on Thermo Fisher Scientific’s PrimaPro Mass Spectrometer, providing precise, representative, real-time analysis.

The sampling systems ensure:

  • Real-time analysis delivered every 7 seconds
  • Representative samples

The systems provide full automation through the whole process:

  • Start up
  • Pre-cleaning sequence – nitrogen purging the sample system filter, linework and take-off probes
  • Pressure let-down
  • Temperature control
  • Mass spectrometer communications and sample delivery
  • Post-cleaning sequence
