| Abstract: | Research on the technology for making ultra-low phosphorus molten steel with re- gard to different processes for steelmaking is carried out. In consideration of the features of equip ments equipped by different production lines, different methods for carrying out the deep dephos- phorization in each of production lines are developed. And as a result the content of phosphorus in steel at tapping is less than 60×10-6 by converter double slag melting process while the content of phosphorus in steel can reach （30-50）×10-6 by converter duplex melting process. During industri- al production test the content of phosphorus in steel is 18×l0-6in making ultra-low phosphorus molten steel by converter. |
