Coiling temperature control using fountain pyrometers in a hot strip mill

In the hot strip mill, the quality of the strip greatly depends on the cooling process between the last stand in the finishing mill and the coilers. Therefore, it is important to carefully control the coiling temperature to regulate the mechanical properties of the strip. To realize high temperature accuracy, a new coiling temperature control using fountain pyrometers has been developed. In this paper, the basic concept and operating results of the coiling temperature control using fountain pyrometers are described.
