摘要： The invention provides a process of producing steels containing nickel, particularly corrosion-resistant steels, which involves refining the metal bath obtained from the smelting of a ferro-nickel by adding to said metal bath in a refining converter ferro-nickel shot while concurrently contacting the metal bath with an oxygen-containing gas, e.g., a mixture of oxygen and argon, the addition of the ferro-nickel shot being carried out while controlling the flow rate of the shot in such a way that the temperature of the converter is maintained at a pre-selected level and the contacting of the oxygen-containing gas with the bath being carried out until the carbon content of the bath is reduced to a low level, e.g., about 0.04%. The inventive process permits the initial carbon and silicon levels of the metal bath to exceed 1% and 0.4%, respectively. The invention also permits the ferro-nickel shot to be added as highly refined ferro-nickel shot or as slightly refined ferro-nickel shot, or it may be added in two phases, the first utilizing slightly refined ferro-nickel shot and the second utilizing highly refined ferro-nickel shot, or both the slightly refined and highly refined ferro-nickel shot may be simultaneously added.
