detail intruduction

noculant is a kind of material which can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups and refine the matrix structure. It has a good effect in a short time (about 5 -- 8 minutes) after inoculation. It is mainly suitable for the general or late instantaneous inoculation of various situations.

Inoculation treatment refers to adding a small amount of other substances to the liquid metal in the solidification process to promote nucleation, inhibit growth, and achieve the purpose of grain refinement. Conventionally, adding additives to cast iron is called inoculation treatment; Adding additives to non-ferrous alloys is called metamorphic treatment. In essence, inoculation mainly affects nucleation and promotes grain dissociation. While metamorphic treatment changes the crystal growth mechanism (inhibiting growth), thus affecting the crystal morphology.


The role of inoculant:

The mechanical properties of gray cast iron depend largely on its microstructure. The gray cast iron without inoculation treatment has unstable microstructure, low mechanical properties and easy to appear white in the thin wall of casting. Inoculation treatment is essential to ensure the consistency of casting quality.

The inoculant used in the inoculation treatment of cast iron has great influence on its microstructure, so it can improve the mechanical properties of gray cast iron, and also has obvious influence on its physical properties. Good inoculation treatment has the following effects:

◆Eliminate or alleviate whitemouth tendency;

◆Avoid supercooled tissue;

◆The morphology of graphite in cast iron is mainly fine and evenly distributed a-type graphite, so as to improve the mechanical properties of cast iron.

The well-bred cast iron has better fluidity, reduced shrinkage, improved machining performance and reduced residual stress.
