ABSTRACT:
A composition for use as a basic flux to aid in obtaining slag fluidity in the production of iron and steel that includes a mixture, as expressed by percentage weight, of iron oxide in the range of 20 to 80%, aluminum in the range of 2 to 80%, and silica in the range of 5 to 60%. A composition for use as an acid flux to aid in obtaining slag fluidity in the production of iron and steel that includes a mixture, as expressed by percentage weight, of sodium oxide in the range of 5 to 50%, aluminum in the range of 2 to 60%, and silica in the range of 20 to 80%. The slag fluidizing ingredients are prereacted forming shaped bodies or powders which are then added as acid and basic fluxes to the steel making furnaces for the purpose of fluidizing the slag thus formed in order to separate and remove the slag from molten metal.
