摘要： 一重生产超纯低压转子钢的工艺流程为EAF-LF-VD-VCD，为了满足超纯低压转子钢的成分要求，在理论分析的基础上，通过实验室实验研究和热力学计算，得到能满足超纯低压转子钢成分要求的高效脱磷及脱硫渣的成分. 其中，在高效脱硫渣中，SiO2含量小于6%可以保证在LF-VD精炼过程中不发生增硅现象，而Al2O3含量为2%~4%则可避免在VD炉真空精炼过程中增铝现象发生. 生产实践证明，研究得到的电炉脱磷渣和LF-VD炉脱硫渣能实现高效脱磷和脱硫，达到超纯低压转子钢的成分要求.

Abstract: The EAF-LF-VD-VCD process for production of ultrapure low-pressure rotor steel is used in Yi Zhong. In order to satisfy the compositional requirements of the steel, based on theoretical analysis, the proper compositions of highly efficient dephosphorization slag and desulfurization slag are determined by the experimental study in laboratory and thermodynamic calculation. Among them, in the desulfurization slag, the content of SiO2 less than 6% can avoid the phenomenon occurrence of silicon increment, moreover the content of Al2O3 within 2%～4% can avoid that of aluminum increment. The production practice shows that the dephosphorization slag of EAF and desulfurization slag of LF-VD optimized by this study can achieve high efficiency of dephosphorization and desulfurization, and meet the compositional requirements of the ultra pure low-pressure rotor steel.

Key words: ultrapure rotor steel, dephosphorization slag, desulfurization slag
