TEMPERATURE MEASUREMENT SENSOR FOR FILLED LAYER AT HIGH-TEMPERATURE AND HIGHLY CORROSIVE ATMOSPHERE, AND TEMPERATURE MEASUREMENT SENSOR INSTALLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a temperature measurement sensor for a filled layer at a high-temperature and highly corrosive atmosphere which can stably measure the temperature of a deadman on the more distal side of a raceway for a long time.;SOLUTION: This temperature measurement sensor 1 comprises a heat- resistant metal cylinder 2 which is hit into a high-temperature coke layer in a blast furnace which generates in-furnace gas from the tuyere of the blast furnace, and a protective pipe 3 of triple structure which in inserted in the installed heat-resistant metal cylinder 2 with a thermocouple 5 held by an insulating pipe 4 accommodated therein.;COPYRIGHT: (C)2003,JPO
