Effective Inoculation of Grey Cast Iron - 2016 …

The study proves that by introducing the iron powder and disintegrated steel scrap to low‐sulphur cast iron still before the inoculation carried out with a conventional graphitising inoculant, the mechanical properties similar to those obtained during the inoculation treatment carried out on cast iron with the recommended high sulphur content are achieved.

Inoculation of grey cast iron with master alloys

The effectiveness of cast iron inoculation performed by means of three various inoculants: FeSiSr – SYSTR75AV, FeSiZr – SYZR 25 AV and Zircinoc was determined. The inoculants were introduced to the cast iron during the pouring of production moulds.

The effect of inoculant amount and casting temperature on

Inoculation of grey cast iron is done primarily to nucleate graphite, to obtain a graphitic eutectic structure free from white solidifiion, or other defects. One important type of defect is caused by metal penetration into the sand mould. The general definition for metal penetration, accepted

Analysis on the problems of inoculation …

Before pouring, a certain amount of substance (inoculant) is added to the molten iron under certain conditions (such as certain superheat temperature, chemical composition, appropriate adding method, etc.) to change the solidifiion process of the molten iron, improve the as cast structure, and achieve the purpose of improving the performance, which is called inoculation treatment. […]

Processing Techniques and Productions of Ductile Iron: A

Ordinary gray cast iron is characterized by a distribution of random lamellae of gra-phite in the metal matrix, while in nodular cast iron the gra-phite has the form of small spheroids. With respect to lamel-lae, the spheroids create fewer and less severe discontinuities in the metal matrix thus producing a stronger, more ductile cast material
