| Abstract: | The effect of BOF end C] on end O] and the effect of LF refining slag ( FeO + MnO) and Als] in steel on liquid O] and finished products TO] are analyzed. With using the process measures including controlling BOF end C] 0.12%~0.15% and amount of slagging out ＜0.10% , controlling Als] 0.015%~0.025% in LF refining, using high basicity tundish shielding agent and special bearing steel GCr15 casting powder, in stable process control condition the TO] in steel ≤10 X 10-6 and the average TO] is 6. 62 x 10-6 |
