Abstract
A process for desulfurizing a bath of molten iron contained in a vessel comprising the steps of injecting particulate lime and a carbon-containing particulate with a non-oxidizing carrier gas beneath the surface of the bath to remove sulfur from the iron, while controlling the rate of injection of the carbon-containing particles to prevent substantial ejection of the bath from the vessel. The preferred carbon-containing materials are graphite and a compound containing at least carbon and hydrogen in proportions ranging from CH.sub.>0 to CH.sub.2. The preferred carrier gas is a hydrocarbon gas.
