| Abstract |
With the view of judging the possibility of reoxidation of Al killed steel, the oxygen potentials of ladle slags were calculated adopting the regular solution model. It was estimated that the activity coefficient of FeO in the ladle slag was 1.497 on the average. The oxygen potentials of the slag and melt for ultra-low carbon steel were higher than those for low carbon steel. In order to decrease the oxygen potential of the slag, it should be controlled to lower Al₂O₃ content and to higher CaO content. The mixture of aluminum and CaCO₃ was found to be more effective than aluminum alone as a slag deoxidizer. |
