Abstract

PURPOSE:To measure a furnace temperature continuously at a high accuracy irrespective of a heated object withdrawing operation, by using a periscope inserted into such a portion of a cooling pipe, connected to a furnace tube, preferably at a location extremely close to the furnace tube. CONSTITUTION:A cooling pipe 6 connected to a furnace tube 3 is bored at that portion of an upper section thereof which is close to the furnace tube 3. A periscope 8 containing a mirror 11 therein is inserted into a bore made as mentioned above, to a depth so as not to contact a material 5 being heated. The radiation energy generated under the inner surface of the upper section of the furnace tube 3 is received by the mirror 11 to be reflected thereon and guided outside the furnace. This energy is subjected to measurement by a two-color thermometer 13 and recorded automatically and continuously by an automatic temperature recorder 15. At the same time, the temperature is automatically controlled by a control means 16. The construction and operation described above permit measuring a temperature, at which the material 5 is treated, continuously at a high accuracy irrespective of a heated material withdrawing operation.
