of cast iron inoculation by ultra- and nanodispersed heat-proof compounds (TiCN, SiC, TiN, AlN, VC) is developed by authors of the paper for large castings and has been under industrial inspection currently. Roll manufacture as the supplier of the most
Cast Irons Miguel Angel Yescas-Gonzalez and H. K. D. H. Bhadeshia Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as
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.

1 Improving Inoculation in Thin Sectioned Ductile Iron Castings Marc King Metallurgist Hiler Industries - LaPorte, IN Introduction: The Kingsbury Castings Division of Hiler Industries has been producing ductile iron using the shell process for molding since the middle
Inoculation of cast iron increased the nuer of eutectic cells with flake graphite and the graphite nodule count in ductile iron, while reducing the undercooling. An increase in intensity of inoculation caused a smooth transition from a cementite eutectic structure
electrically melted base iron having 0.025% S, 0.003% Al and 3.5% Ce is excessively high (39 – 40 ), generating a relatively high need for inoculation. Under these conditions, the in-mould inoculation has a more signiﬁ cant effect compared to ladle inoculation

This is called inoculation fade. The use of late or in stream inoculant (typically in sizes of 0.2 x0.7 mm, and often called GSK or MSI grade) or in-mould inoculation from cast block inserts reduces the chance for the particles to coalesce and additions of 0.05 to 0.1
Ductile cast iron round bars were prepared using alloys with carbon equivalent percentage (C.E) ranging between 4.50 % and 4.76 %. Different measurements were carried out on as – cast and heat-treated specimens. Ductile cast iron is essentially a family of
CAST IRON INOCULAtion THE TECHNOLOGY OF GRAPHITE SHAPE CONTROL ISO 9001 ISO 14001 ISO/TS 16949 CAST IRON INOCULATION THE TECHNOLOGY OF GRAPHITE SHAPE CONTROL Elkem manufactures and markets a series of high quality inoculants to treat cast iron and ensure the production of an ideal graphite shape, distribution and freedom from chill (cementite).
INOCULATION AND ITS INFLUENCE ON THE STRUCTURE AND PROPERTIES OF GRAY CAST IRON: Inoculation is defined as the late addition of an element or elements to the molten iron to produce changes in graphite distribution, improvements in mechanical properties, and a reduction of chilling tendency that are not explainable on basis of composition changes with respect to silicon.
