| Abstract: | There are quality defects such as cracks, scab, hard spots and peeling in X1215 sulfur - system free - machining steel of Xuan Steel. The defect parts are examined and analyzed. It is discovered the main rea- son is large- size inclusion and casting billet surface needle holes. The products quality gets obviously im- proved by adjusting refining process, controlling accurately the activity oxygen at end of refining and impro- ving quality of refractory materials. |
