DEVICE FOR CONTINUOUSLY MEASURING THE TEMPERATURE OF INGOT STEEL OF A CONTINUOUSLY CASTING MOLD FOR A LONG TIME IN A STATE OF BEING DEPOSITED IN INGOT STEEL IN THE MOLD

摘要

PURPOSE: A device for continuously measuring the temperature of ingot steel of a continuously casting mold is provided to enable the temperature of ingot steel in a mold to be continuously measured for a long time by protecting thermocouple in a dual structure, an inner protecting pipe of an Al2O3 material and an outer protecting pipe of a ZrO2-C series material.;CONSTITUTION: A device for continuously measuring the temperature of ingot steel of a continuously casting mold comprises a thermocouple(21), an inner protecting pipe(25) and an outer protecting pipe(27). The thermocouple uses platinum. The thermocouple is built in the inner protecting pipe. The inner protecting pipe is formed from alumina. The outer protecting pipe is formed to protect the outer part of the inner protecting pipe. The outer protecting pipe is formed from Zr-C series fireproof material. The Zr-C series fireproof material consists of 70~85 weight% of ZrO2, 15~30 weight% of C and inevitable impurities.;COPYRIGHT KIPO 2012
