Abstract：The total oxygen content、the types and area percentage of the non-metallic inclusions in 430 hot-rolled plate corresponding to the head blank, last blank, mixed-casting slab and normal slab were analyzed by means of OM and SEM．The results show that the CaO-SiO2-A12O3 ciliate inclusion and the Al2O3-MgO-CaO globular oxide inclusion are the main inclusions in the 430 ferritic stainless steel; the total oxygen content in 430 hot-rolled plate corresponding to the head blank、last blank、mixed-casting slab are 41×10-6、39×10-6 and 37×10-6 respectively, are higher than 28×10-6 of the normal slab; the area percentage of the non-metallic inclusions in 430 hot-rolled plate corresponding to the head blank、last blank、mixed-casting slab are 0.031％、0.028％ and 0.039％ respectively, are also higher than 0.02％ of the normal slab.
