| Abstract: | Analysis the distribution characteristics and the causes of subcutaneous bubbles in cast slab of the 1215MS high-oxygen and high-sulfur free cutting steel. By controlling the total oxygen content in the steel， adjusting the parameters of the M-EMS， and improving the physical and chemical properties of the mold powder， significantly improve the bubble defects，Thereby improving the surface quality of steel and the finished product. |
