Inclusion Characteristics in Stainless Steel Ingots

Abstract

Inclusions in 316L stainless steel ingots poured using two different upgate designs - a traditional upgate and a swirl upgate - were investigated using SEM and ASPEX automated inclusion analysis. the main inclusions were high SiO 2 inclusions, MnS inclusions and SiO2-Al2O 3-CaO inclusions. More inclusions were detected at the top of the ingot than other places in vertical direction, and more inclusions were at the edge of the ingot than other place in the radial direction. with swirling upgate there were more K- and Na- bearing inclusions than that with the traditional upgate indicating possible more serious flux entrainment with the swirl upgate.
