Abstract

PURPOSE: To improve characteristics of being reduced and a low temperature reduction degradation ratio, by sintering a powdered ore mixed with mixed powder at a prescribed temperature.
CONSTITUTION: A powdered ore is, if necessary, mixed with the mixed powder of e.g. SiO2, CaO, Al2O3 and the like. The mixture is sintered at 1,100W1,315°C. In this way, the formation of skeletal crystal-like rhombic hematite is restrained, needle-like calcium ferrite is formed and the low temperature reduction degradation ratio and characteristics of being reduced of the sintered body are improved.
