ABSTRACT:
A temperature scanner for use in a hot strip rolling mill to enable ready determination and analysis of the temperature distribution over a hot strip of material passing through the mill. The temperature scanner comprises a photocell scanner unit 1, situated over and scanning a strip 2 perpendicular to its direction of travel, electronic analyzer 6 connected to the scanner unit via lead 5 and displayer 7 connected to the analyzer 6 by lead 8. The analyzer 6 compares the temperatures detected with a reference level set and together with the displayer 7 displays a map of the strip surface in which areas at temperature above the reference level are distinguished from those below the reference level. Alternatively, one or more temperature profiles corresponding to one or more scans of the surface are displayed, in which temperatures above the reference level are distinguished from those below the reference level.
