Abstract
A plurality of thermocouples are embedded close to each other with individually different depth in a temperature detecting block. One or more of the temperature detecting block are attached to the surface of a thermal sensor roll. When the thermal sensor roll is held in contact with a metal strip being rolled, temperatures in the thermal sensor roll are measured at a plurality of points. The temperature of the metal strip in contact with the surface of the thermal sensor roll is calculated from the graduation of a temperature in the thermal sensor roll along a direction vertical to the surface of the thermal sensor roll, without the influence of disturbances. The obtained temperature value of the metal strip being rolled is compared with an experimentally obtained temperature of heat streak formation, to predict the formation of heat streaks with high accuracy.
