摘　　要：为提高鞍钢三炼钢生产的IF钢质量,对三炼钢转炉-RH精炼-连铸生产IF钢的工艺过程开展了较为系统的分析研究。研究发现试生产中RH真空精炼过程[C]含量过高,浇铸过程中增碳、二次氧化比较严重,经改进调整之后,铸坯中w(C)在30×10-6左右,w(N)在25×10-6以下,w(T.O)在20×10-6左右,达到了较高的洁净度水平。In order to improve the quality of IF steel. a systematic investigation in BOF RH CC process route for production of the steel has been made in No.3 Steel making Plant of Anshan Steel Corp. Results show that [C] content in the slab exceeds the limit of IF steel in vacuum refining and carbon pick up and reoxidization tremendously occurs during continuous casting. By appropriate readjustment of technologies the [C] content in slab has been cut down to about 30 ppm, [N] to 25 ppm and T[O] to 20 ppm and thereby higher level of cleanliness attained for the slab.
