In this paper a trial for establishing the correlation between the reducibility and mineral constitution of lime added sinter is reported. For this purpose, the authors used the specimens produced by a small sintering apparatus by Yawata Iron and Steel Co. In these specimens simultaneously with the increase in the quantity of limestone, an decrease in the quantity of hematite and an increase in the quantity of calcium ferrite were found. A good accuracy was obtained in the measurement of the samples consisting of homogeneous phases by the apparatus of thermal balance used in this experiment. Judging from the result of the reduction test of lime added sinter, the reproducibility was not so good and the correlation between the contents of limestone and reducibility was not clarified in the measurement of so complicated materials in the mineral composition as this sinter.
