Study on Inclusions of AISI304 Casting Thin Strip
The types and the amount of large inclusions in AISI304 stainless steel strip produced by twin-roll caster were investigated by sample-electrolysing method,and the types of fine inclusions in the strip were detected by scanning electron microscopy(SEM) equipped with energy dispersive spectrometer(EDS).The results show that the number of large inclusions is very little,which is only about 0.001 5wt% of the total thin strip and majority of large inclusions are oxides.The types of fine inclusion in the strip are oxide and MnS.The large inclusions almost have little influence on the casting strip and the the 304 strip has good mechanical properties.
