Investigations of the Dephosphorization of Liquid Iron
Jan 14, 2012· Up to12%cash back· The most up-to-date trends in stainless steel production—aiming at the reduction of production costs—consist of the substitution of steel scrap by hot metal, coming from the reduction of iron-chromium ores. This process requires a more extensive dephosphorization. The dephosphorization process, when applied to chromium steels, requires slag with high dephosphorization Investigations of the Dephosphorization of Liquid Iron,ization process, when applied to chromium steels, requires slag with high dephosphorization properties, as either chromium or chromium oxide entering the slag decreases distinctly the eﬃciency of the process. The results of laboratory investigations on the dephosphorization of liquid iron solutions containing chromium and nickel are presented.

Because the solubility of phosphorus in the liquid iron was relatively high, generated P 2 was absorbed by the liquid iron, resulting in the stability or even decrease of the dephosphorization extent. In the analysis, the 1000–1100 °C temperature range was considered the best period for the vaporization dephosphorization.Tensile properties and fracture toughness at service,The base melt batch used in the present investigation was prepared in a medium frequency induction furnace (250 Hz, 12000 kW) with 16 t in capacity. The metallic charges were composed of about 45% steel scrap and 55% ductile iron returns.
