Inoculants for graphitizing treatment of irons

Graphitization of cast irons involves introducing chemically active elements into them when they are liquid, which contributes to the formation of additional graphite nucleation sites.

Graphitization makes it possible, among other things, to achieve the following objectives:

• to prevent formation of cementite in the structure of cast irons
• to reduce the likelihood of appearance of gas- and shrinkage-related porosity defects
• to improve the mechanical properties of irons
• to make the structure of irons more uniform in sections of castings having uneven wall thicknesses

Our company offers the following grades of efficient inoculants with microcrystalline structures for graphitizing gray and ductile irons:
SIBAR®, R-GRAPH®, Z-GRAPH®, Si-extra®, ZIRCALLOY®, INOCSIL®

Depending on the method of introducing inoculants into liquid irons, the sizes of inoculant particles may range between 0.2 and 20 mm.

Inoculants are supplied in PE-lined big bags with capacities of 0.5 and 1.0 tons and, at the customer's option, in paper bags with capacities between 5 and 25 kg.
