Synopsis : On the basis of findings of Si content changes in pig iron produced in recent years at blast furnace of Chiba and Mizushima Works, the methods of smelting a low Si pig iron in blast furnace are discussed from the viewpoints of chemical reaction kinetics and liquids flow in the packed bed. Relations of blast furnace operational variable and characteristics to Si contents in pig iron are analyzed using actual data. With a possible target of Si content in pig iron in the near future proposed to be around 0.1%, the paper also discusses some problems which must be solved in attaining the target with a stable furnace operation. |
