higher reducibility of iron ore burden at lower temperature is required under higher hydrogen condition. Iron ore sinter, pellet, and lump ore are typical iron burdens of BF, and especially sinter is major one in East Asian countries. It is well known that main mineral phases of sinter are hematite, magnetite, calcium ferrite, and slag.

In the present study, disintegration behavior of a sinter sample at 773 K for 3.6 ks under gas flow of N. 2–CO–CO. 2–H. 2O system was examined. The results showed a remarkable increase in the reduction degree and reduction-disintegration index (RDI) upon the addition of a small amount of H. 2. However, further increase in the H.
