Cast Iron Inoculation Enhanced by Supplementary Oxy …

Inoculation is one of the most important metallurgical treatments applied to the molten cast iron immediately prior to casting, to promote solidifiion without excessive eutectic undercooling, which favors carbides formation usually with undesirable graphite morphologies. The paper focused on the separate addition of an inoculant enhancer alloy [S, O, oxy-sulfides forming elements] with a

Inoculation of ISTs grade high-chromium cast iron with …

To improve the wear resistance of high-chromium cast iron ISTs (3.0% C, 20.1% Cr, 1.0% Si, 0.75% Mn), it was inoculated with Al 2 O 3 ultra-dispersed powder. The wear resistance of castings exposed to abrasive wear is examined. Evidence shows that the

Inoculation of Grey Cast Iron and the Influence on Metal …

In some grey cast iron components which are cast in sand moulds, the metal some time penetrates into the mould producing surface defects and causes difficulties when cleaning the components. The present work utilizes the latest development of primary austenite inoculation in coination with classic eutectic inoculation to limit the metallurgical contribution to metal expansion penetration.
