Continuous Gas Measurement in Heat Treatment Furnaces

Continuous on-line NDIR measurement of CO, CO2 and CH4 to optimize heat treat process

Analyze corrosive gases without consequence

On-line continuous gas analyzer ULTRAMAT 23 enables you to control the atmosphere to obtain the desirable heat treat effect repeatedly and more economically.

Annealing furnaces require heat and a specific operating atmosphere to remove carbon from steel.  Typical Heat treatment furnace atmosphere constituents are oxygen, carbon monoxide (CO) carbon dioxide (CO2), Hydrogen (H2) or Methane (CH4).  The specific atmosphere depends on the type of heat treatment application.   Consequently, the continuous measurement and control of specifically CO, CO2, and CH4 is of importance.  The Siemens ULTRAMAT 23 continuously measures the concentration of up to 3 gases.  Utilizing ambient air for calibration simplifies and reduces operational cost.  Because the sample does not come in contact with the measuring sensor, corrosive gases can be analyzed without consequences.  Hence, simple calibration, long term repeatability and low cost of ownership to manufacture consistent steel quality.
