Abstract

In situ Reaction Vertical Probe which is able to estimate the both effects of mechanical force and reducibility in the blast furnace has developed.
Several types of sinter with different RDI were charged into an operating blast furnace. After the recovery of the sinter, degradation was observed.
It was ascertained from the investigation that as the RDI value of the sinter increased, its in-furnace degradation ratio became higher, and that the RDI value was almost equal to the degradation ratio when the sinter was kept in a low temperature reserve zone (about 60 minutes in this test).
