Use of Industrially Produced Synthetic Slag at Třinecké Železárny, A.S.

Use of Industrially Produced Synthetic Slag at Třinecké Železárny, A.S. The paper summarises experience with using synthetic slags on the CaO - Al2O3 oxide basis in the technological flow of the oxygen converter steelworks in TŘINECKÉ ŽELEZÁRNY, a.s. These slags are used as an alternative to slags containing fluorspar which unfavourably affects both the service life of ladle linings and the steelwork's working environment. The content gives the first knowledge of using the Refraflux type synthetic slag to desulphurize steel, and it also provides a basic statistical evaluation of the heat produced.
