Phosphorous Enrichment in Molten Adjusted Converter Slag： Part I Effect of Adjusting Technological Conditions

The effects of adjusting technological conditions on the phosphorous enrichment of adjusted converter slag were investigated. The results showed that the phosphorus could he effectively enriched to 2CaO · SiO2 and 2CaO · SiO2-3CaO· P2O5 solid solution （SS, namely phosphorus-rich phase） to be formed...

Zusammenfassung:	The effects of adjusting technological conditions on the phosphorous enrichment of adjusted converter slag were investigated. The results showed that the phosphorus could he effectively enriched to 2CaO · SiO2 and 2CaO · SiO2-3CaO· P2O5 solid solution （SS, namely phosphorus-rich phase） to be formed with the decreasing of basicity and cooling rate. Moreover, the morphology of the phosphorus-rich phase changed from granular for the original converter slag with higher basicity to the coexistence of granular shape and rod-like for the adjusted slag with lower basicity. P2 05 content in phosphorus-rich phase exceeded 30° while the hasicity was 1.3 at the cooling rate of 1.0 ℃/min.
