In this study, we discussed the control of casting structure to improve the forming and ridging quality of ferritic stainless steels of which the casting structure in the continuous casting process directly affects the final product's quality. For refining the casting structure of ferritic stainless steel, EMS optimization was developed in continuous casting process. Moreover heterogeneous nucleation technology was developed through oxide control in deoxidation process. As a result, the forming and ridging quality of final product could be improved through the refinement of the casting structure, furthermore the low temperature ductility of welding region was improved by refining the solidification structure of that through the oxide control technology.
