Blast furnace
Target metal: Iron with slag
Application overview at tap hole and torpedo ladle
Challenges
- Lots of smoke and dust
- Combustion gases
- Sparklers
- Erratic emissivity, varies with temperature, wavelength and chemical composition
- Variable position of iron stream (moving target)
- Very large measuring distance, up to 100 meters
Measured Process Variables, typical data
Benefits
- Live data
- Separate data for iron and slag
- No more safety hazards (compared to taking thermocouple readings)
- Insight into process inside BF by measurements at the tap hole
- Valuable information for steelmaking shops from measurements at the torpedo ladle
Similar processes to which A.I.R.T technology can be applied
- Foundries for ferrous and non-ferrous metals (stainless steels, aluminum, copper,…)
- Steelmaking
