| 摘 要： | 结合实际生产数据,分析了转炉终点控制对RH真空脱碳的影响,分析认为,冶炼超低碳钢时,转炉终点碳含量≥0.05%,需要进行RH强制脱碳;终点碳含量≤0.04%时,可以进行RH自然脱碳,也可以在出钢过程中进行最大810kg的微碳锰铁（锰含量80%）合金化操作。底吹氩2min降低钢水氧活度约190×10-6。没有底吹终点钢水碳含量不均匀,均匀性相差0.01%～0.02%。

| Abstract: | Combining with the actual production data,this article analyzed the influences of the BOF end-point control on RH vacuum decarbonization.For ultra-low-carbon steel,when the carbon content in BOF end-point was not less than 0.05%,it required enforced decarbonization in RH treatment.When the end-point carbon content was not more than 0.04%,might make RH natural decarbonization and might make alloying operation by adding not more than 810 kg of trace carbon manganous iron（with 80% manganese content） in tapping course as well.Blowing argon for two minutes decreased the oxygen activity in molten steel by about 190×10-6.No bottom blowing,the end-point carbon content in molten steel was asymmetric and the discrepancy was from 0.01% to 0.02%. |
