| Abstract: | This paper analyzes the reason that caused the surface defect of billet produced by EAF Steelmaking plant of Nanjing Iron and Steel Co. Ltd. The main reasons were attributed to unsuitable mold oscillation parameters and mold powder. Through optimizing the oscillation parameters and mold powder properties, the hook mark defect of billet was eliminated and the surface quality improved obviously. |
