The effects of adjusting technological conditions on the phosphorous enrichment of adjusted converter slag were investigated. The results showed that the phosphorus could be 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. P2O5 content in phosphorus-rich phase exceeded 30% while the basicity was 1.3 at the cooling rate of 1.0 ℃/min.
