Steel sheet thermometry device null between high-temperature strip mill

摘要

PURPOSE: To measure the temperature of a steel plate between stands of a continuous hot press roll. ;CONSTITUTION: An optical fiber 14 is fitted to a lens system 13. The light radiated from a steel plate and condensed by the lens system 13 is transmitted to a temperature detector set outside a press roll in the good environment. The data of the temperature is changed to electric signals by the temperature detector. One end part of the lens system 13 and the optical fiber 14 is coated with a water-cool jacket 15 having a heat-shielding plate 16 so as to be protected from the radiation heat of the steel plate or the like.;COPYRIGHT: (C)1994,JPO&Japio
