説明

In Japan, the temperature measurement of liquid steel is generally made with the aid of an disappearing-filament optical pyrometer. Since the beginning of 1935, the 19th Sectional Committee of the Japan Society for the Promotion of Scientific Research have endeavoured to establish the manner of calibration and to study the suitable method of measurement with an optical pyrometer. A standard electric lamp has been developed, with which acting observers of several steel works were assembled many times to measure the temperature of liquid steel simultaneously. After a long discussion, the value of emmissivity was tentatively determined to be 0·45 in the usual case of the steel casting period under tundishes or ladles. In the present paper, the means for measuring the temperature of liquid steel, was fully explained, the emmissivity value being taken as 0·45.
