DEVICE FOR MEASURING THE TEMPERATURE OF A ROLLING MATERIAL

摘要

The present invention relates to a device for measuring the temperature of a rolling material, wherein a non-contact temperature measuring apparatus provided outside the upper part of a furnace measures the temperature of a rolling material moving inside the furnace through a sensing hole formed in the ceiling of the furnace, at which time a cover housing member moves downwards through the sensing hole and makes contact with the surface of the rolling material and the temperature is measured in this state, thereby making it possible to accurately measure the temperature of the rolling material being heated in the furnace.
