【 摘 要 】

The paper proposes a method for processing steelmaking slag for the purpose of resource saving. The authors propose to include partial granulation of steelmaking slag in the processing scheme. This embodiment includes draining of molten slag from the steelmaking unit in the bucket and separation of the molten slag into two parts, one of which is enriched in iron. With the use of statistical processing dependence for determination of content of FeO content in the converter slag was received. The resulting granulated product can be recommended for use in construction, in agriculture as a fertilizer, as well as a slag-forming flux in steelmaking.
