STEEL SHEET TEMPERATURE MEASUREMENT METHOD OF PYROMETER

摘要

The cold steel plate temperature measuring method of a pyrometer of measuring the surface temperature of the cold steel plate by absorbing the wave length emitted from the surface of the cold steel plate, is characterized in that the temperature is measured by detecting the wave length which is emitted from a reflecting region 109 of wedge shape adjacent to the contact surface 250 of the cold steel plate S and a roll 220 with being inclined by a predetermined angle against the processing direction of the cold steel plate S.
