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.

Temperature control of a hot strip has been important in run-out table of hot strip mill in order to stabilize and improve the material properties of its products. We developed a new temperature measurement method for hot stripcooled by a lot of water in the cooling banks. And we developed control system using the new measurement method and confirmed that the system could control hot strip temperature accurately. We explain the principle of the new measurement method and its online test result in this paper.
