摘　　要：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.The effects of adjusting technological conditions on the phosphorous enrichment of adjusted converter slag were investigated.
