摘　　要：通过对脱硫铁水在转炉冶炼过程中回硫的各种因素进行分析,得出影响回硫的主要原因是铁水硫含量、转炉留渣、及石灰硫含量等,提出了冶炼低硫钢减少回硫的主要措施,通过工艺改善,降低了转炉终点硫含量。By analyzing factors causing to the hot metal resulfurization in the process of hot - metal desulphuriztion in converter refining the main reasons for resulfurization aredetermined to he the sulphur content in the hot metal, existence of slag remainder in converter and the sulphur conten in the lime. The proper measures are suggested in ordei＂ to reduce resulfuriza - tion in refining low sulfur steel.
