INFLUENCE OF CONTAINING Ba DEOXIDIZER ON QUALITY OF STEEL STRIP
-
摘要: 通过BaCaAlSi与SiC在出钢过程的脱氧试验对比,研究了两种脱氧剂对成品板材质量的影响。采用Ba CaAlSi和SiC作脱氧剂时,板材中的全氧含量分别为14.8×10-6和17.8×10-6;氮含量分别为48.6×10-6和53×10-6。结果表明,采用BaCaAlSi脱氧时成品板材的内部质量较好。Abstract: The influence of two different deoxidizer BaCaAlSi and SiC on quality of steel strip were investigated by contrasting the deoxidizing practice of BaCaAlSi and SiC in steel tapping. The T[O] is 14.8×10-6 and 17.8×10-6 respectively, [N] is 48.6×10-6 and 53×10-6 respectively in steel strip when adopting BaCaAlSi and SiC as deoxidizer. The results show that the inner quality of finial strip is better using BaCaAlSi than using SiC.
