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

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,…)

Similar processes to which A.I.R.T technology can be applied

• Aluminum extrusion
• Copper and brass extrusion
• Aluminum forging
• Copper and brass forging
• Hot rolling of stainless steel
