High-resolution thermal scanning for hot-strip mills ...

1. MAIN STEEL APPLICATIONS In the steel industry, IR-scanners are mainly used in the hot-strip mill, at the exit of the reheating furnace, at the rougher, after the finishing-stand and before coiling (see fig. 1). We shall therefore look at the usefulness of linescanners in these locations.
