A temperature sensor for detecting temperature and heat flux on the roll surface in rolling has been developed. Installed in a roll surface, this sensor detects two temperatures at different depths from the roll surface by thermocouples. Surface temperature and heat flux are calculated from the two measured temperatures using the reverse calculation method for one-dimensional unsteady thermal conduction. Temperature distribution and heat flux distribution on the roll surface are measured in the cold rolling of aluminum sheets and billets. The availability of this sensing method for the investigation of thermal phenomena in rolling is discussed.
