Abstract In order to determine the inclusions of 45A Caster ,in this paper ,with the help of metallographic observation、SEM and big sample electrolysis ,slab inclusion type, shape, dimension and distribution of arc caster have been studied .The results showed that：the whole control level of inclusion is well.The average of the amount of inclusions is 22.2mm-2,but in the middle of the caster inclusions is 25.8mm-2；With the help of big sample electrolysis，SEM，found that the total amount of inclusions of cast is 2.23mg/10kg，and inclusions is more than 300μm.Large inclusion come from mould fluxes、oxidation products、tundish covering flux and so on.
