| Research Abstract |
This works aimed at increasing the efficiency of blast furnace operation in steel industry. To do so, a practical method to promote the slowest solid-solid reaction, reduction of iron ore by coke itself, was proposed. First, it was shown that the solid-solid reaction actually proceeds at as low as 600 C by using nano sized Fe2O3 particles as a model iron ore. Next, a method to realize the rapid solid-solid reaction in blast furnace was examined. It was found that inserting thermo-plastic carbonaceous materials prepared from low rank coal into nano-sized pores formed in a low grade iron ore by hydration is effective to realize the rapid solid-solid reaction.
