Production of high purity aluminium killed steel^*

Élaboration d'acier calmé à l'aluminium de haute pureté

C.M. Lee, I.S. Choi, B.G. Bak and J.M. Lee

Abstract

The manufacturing technique of D and I steel has been improved at Pohang Works, Poseo. The improvement of slag control, the utilization of RH-OB flux refining facility and the application of tundish filtering dam allowed the improvement of steel cleanness for D and I steel. Consequently, the flange crack ratio of D and I steel was significantly reduced.
