ABSTRACT OF DISCLOSURE This invention relates to a method of making steel in a bottom-blown converter from a charge of solid metallic iron-?aring materials wherein the charge is melted down without an addition of liquid pig iron in order to avoid uncontrolled flow conditions with the aid of burners which form a molten sump, fine-particled carbon and oxygen being separately injected into said sump through tuyeres which are disposed below the burners. The burners may be sited either slightly above the final upper surface level of the melt or below said level, and in the latter event the burners may be operated as additional tuyeres after they are submerged in the melt.
