摘　　要：主要从RH精炼的角度研究如何降低O5板的成品氧。在进行了大量的现场调研和理论分析的基础上,确定了影响O5板成品氧的三个主要因素:RH脱碳终游离氧、最低真空度和镇静时间,分别研究了他们对O5板成品氧的影响规律。同时,采用化学滴定法、X荧光法和重量法分析得出RH精炼渣成分,并计算出其光学碱度,与理论分析得出的关于深脱氧的最佳光学碱度相比较,以判断该精炼渣是否满足深脱氧的要求。计算结果表明,O5板RH精炼渣的光学碱度为0.76,与理论计算得出的最佳碱度0.84相比,还有待提高。How to reduce the total oxygen in the O5 automobile plate was investigated in terms of the RH refining.Based on a great amount of on-site research work and theoretical analysis,three major factors affecting the total oxygen in the O5 automobile plate were determined:free oxygen after decarburization,minimum vacuum degree and holding time.The influence of the three factors on the total oxygen in the finished product was studied respectively.At the same time,with the chemical titration,X-fluorescence and grav...
