| Abstract: | The paper explains the practice that adopts BOF—LF—RH—CC process to produce low nitrogen and ultra low nitrogen steel for automotive panels.On the basic of the analysis of nitrogen content in steel,combined with production practice,proposed some improvements,for example,changes the pattern of converter＇s bottom blowning,using the effective LF submerged arc refining slag,RH plugging and Protected casting,etc.,so that the average nitrogen content of slab to 0.0018%,to satisfy the product requirements. |
