Technology
Sample applications
Molten metals
Hot rolling, Extrusion and Forging
Annealing
Aluminum hot rolling
Target metal: miscellaneous aluminum alloys
Application overview: reheating furnace, roughing mill, finishing mill, Coiler
Challenges
Very low and erratic emissivity, varies with temperature, wavelength and alloy
Background reflections from the sun, lighting and hot furnace walls
Measured Process Variables, typical data
Temperature
Emissivity spectrum, relative level of oxidation
Benefits
Live data for complete production run, history of each coil can be fully documented
No need to stop to make thermocouple measurements
Surface condition data provide valuable insight into process
Surface condition data help detect quality problems (Blisters,…)
