| Abstract: | Effects of M-EMS on surface cleaniness of IF steel slab were investigated by means of SEM, EDS and microscopic techniques, etc. The results indicate that M-EMS can improve surface cleanliness and reduce inclusions, blow hole defects effectively. Al2O3, TiN and Al2O3-TiN, Al2O3-Ti2O3, Al2O3-Ti2O3-TiN are main inclusions in the slab. The distribution of bubbles in slabs is non-homogeneous in respect of width and depth, the bubble size range of 50 to 350μm. |
