Pretreatment agent for steelmaking molten iron

A pre-treating agent for the molten iron used for smelting steel contains the iron oxide (60-80 Wt%) chosen from FeO, Fe2O3 and Fe3O4, mixture of calcium oxide powder (20-40), and powdered deforming agent (0.5-1.5). Its functions include de-siliconizing, desulfurizing, dephosphurizing, decreasing C...

Zusammenfassung:	A pre-treating agent for the molten iron used for smelting steel contains the iron oxide (60-80 Wt%) chosen from FeO, Fe2O3 and Fe3O4, mixture of calcium oxide powder (20-40), and powdered deforming agent (0.5-1.5). Its functions include de-siliconizing, desulfurizing, dephosphurizing, decreasing C and reducing to low-valence Fe to high-quality high-valence Fe.
