ON-LINE PHASE TRANSFORMATION MONITORING ON A HOT STRIP MILL
The EMSpec sensor employs the principle of measuring the complex impedance of the target steel over a range of frequencies these impedance values in turn varies with transformation fraction of the steel. A full scale implementation of the Real Time Transformation Monitoring has been installed at a quality large European steel producer to show the benefits of such a system.

Temperature Monitoring for Hot Rolling Mills | Williamson
Temperature Monitoring. Temperature Control in Hot Rolling Mills. Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams).

Conventionally, the temperature of a hot strip on a hot-run table was measured at three points as shown in graph 1. At these three points of just after being rolled out (referred to as FT in Graph 1), in-between two cooling banks (IT in Graph 1), and before the coiler (post-cooling temperature; CT in Graph 1), the temperature was measured by pyrometers(*3) and then …

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
