Influence of inoculation on solidifiion in cast iron | …

Inoculation of cast iron has been mainly studied for the nucleus materials and the development of new inoculants. The effect is widely recognised; nevertheless, the mechanism was not fully understood.

An inoculation phenomenon in cast iron - INFONA

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

What is inoculation? - Free Online Library

1/1/2004· Inoculation is a common and necessary practice used in foundries that produce gray and ductile iron castings. Often performed just prior to pouring, inoculation refers to a procedural step undertaken to improve the solidified structure of the metal, and therefore its mechanical properties.

Additive for inoculation of cast iron and method - Loper …

25/7/2006· The necessity of inoculation for different types of cast iron is determined by the thermodynamic nature of the molten iron as determined by the iron-carbon equilibrium diagram, which exhibits both stable (iron-graphite) and meta stable (iron-cementite) liquid-solid

Why inoculation required in cast iron castings? Which is …

Cast iron is susceptible to a problem called chilling. Some edges and particularly thin, pointed or long parts of a cast part may cool off much faster and freeze without allowing graphite to precipitate out as flakes. Graphite precipitation provid

The Purpose of Inoculation for Cast Iron

In modern inoculation technology, the corresponding Inoculant can be selected according to the performance requirements of different cast iron parts. For example, a graphitized inoculant with strong graphitization is used to make high toughness ductile iron; a stabilized inoculant with pearlite and alloying is used to improve the strength, hardness and wear resistance of castings.
