Abstract

PURPOSE: To improve desulfurization rate by adding metallic Al powder at the specific rate to the desulfurizer consisting essentially of alkali metal oxide for molten iron.
CONSTITUTION: Any of anhydrides, hydrates or bicarbonates of one or more kinds among potassium carbonate, sodium carbonate, caustic soda, caustic potash, sodium potassium carbonate, etc. are used in the form of powder, granules, lump or flake. To this is mixed power or granular form metallic Al at 1W30% expressed in terns of purity. These both components are mixed just before the use or are charged simultaneously as separate packages. The combination use of metallic Al improves desulfurization rate by 5W12%.
