What is the influence on a measurement when the roll temperature varies (descend) during a measurement?
See answer to question 5. It is possible to take successive scans along the barrel of a roll over a period of say 2 hours – as the higher temperature at the roll centre soaks out to the necks. The instrument is zeroed at the start of each scan in the normal way and the variation in diameter (roll profile) measured. There is a facility in the software to display the decay of thermal camber by displaying the multiple profile traces in 3 dimensions with user definable angle of rotation and colour banding.
