Reaction mechanism on the smelting reduction of iron ore ,

The kinetics of the smelting reduction of iron ore by a graphite crucible and carbon-saturated molten iron was investigated between 1400 176 C and 1550 176 C, and its reaction phenomena were continuously observed in situ by X-ray fluoroscopy In the smelting reduction by graphite, it was shown from the observation results that the smelting reduction reaction proceeded by the ,...

Smelting reduction of iron ore

In the smelting reduction process described the reduction of iron ore occurs in three stages in the first step the ore is preheated and prereduced in a cyclon-heat exchanger system In the second step it is melted The final reduction of the partially reduced and melted ore to metallic iron takes place in the MIP reactor Citing Literature...
