If you want to buy a product well, you must have a deep understanding of the role of this product. Inoculant can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic clusters and refine the matrix structure. It has a good effect in a short time (about 5-8 minutes) after inoculation treatment. It is mainly applicable to general natural parts or later instantaneous inoculation in various situations. Here is the function of inoculant:
(1) Eliminate or reduce the tendency of white mouth;
(2) Avoid supercooled tissue;
(3) Reduce the sensitivity of wall thickness of iron castings, so that the difference of microstructure and hardness between thin and thick sections of castings is small;
(4) Conducive to the nucleation of eutectic clusters and increase the number of eutectic clusters;
(5) The morphology of graphite in cast iron is mainly fine and evenly distributed type a graphite, so as to improve the mechanical properties of cast iron.
(6) The cast iron with good inoculation has good fluidity, reduced shrinkage, improved machinability and reduced residual stress.
