In order to better understand and develop the technology of integrating dephosphorization decarburization in a single converter (abbreviated as IDDSC), relevant thermodynamic issues were discussed by calculation. Based on calculation, bridges between phosphorus distribution ratio, temperature, slag composition constructed. Besides, connections behavior microstructure also established investigat...

Utilization of CO2 in steelmaking process has attracted extensive attention recent years, not only because its social benefits, but also better metallurgical performance. Mixing with O2 blown by converter oxygen lance is gradually being adopted plants, due to potential reducing consumption and improving steel quality. In the present research, effect mixing on jet characteristics a four-nozzle w...

In the present work, effect of dephosphorization endpoint temperature on hot metal was studied for double slag converter steelmaking process under conditions low and basicity by industrial experiments. range 1350–1450 °C, with an increasing temperature, ratio phosphorus distribution first increase then decrease. The content in decreases increases at end dephosphorization. At 1385–1410 is higher...

The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...
