Abstract
A method of treating molten metal in a converter having an induction heater the heating space of which opens into the lowermost portion of the converter compartment comprises injecting a mixture of a solid treating material in powder form with a carrier gas through a sidewall of the converter at a level only slightly above the bottom wall of the converter compartment. A tuyere through which the gas-powder mixture is injected is directed slightly downward and toward the region where the heating space of the induction heater opens into the converter compartment.
