摘　　要：针对300t RH处理超低碳铝镇静钢的生产数据,分析了RH处理过程中钢中总氧和夹杂物含量的变化。分析讨论了吹氩强度、顶渣成分、处理时间、初始溶解氧含量和处理过程中的二次氧化等对钢中夹杂物和总氧含量的影响,为生产优化RH处理工艺,进一步提高钢水洁净度提供了技术支持。According to the production data about ultra-low-carbon （ULC） Al-killed steel produced by RH（300 t） process, the present paper analyzes changes of the total oxygen content and the amount of inclusions in steel during the RH process and discusses the effects of the processing factors such as the argon blowing intensity, the chemical compositions of the top slag, the treatment time, the initial dissolved oxygen content and oxygen pickup in the processing on the inclusions and total oxygen amount in steel, thus providing the technological support for further optimizing the RH treatment process and raising the cleanliness of liquid steel.
