They are introduced into the gating system of a mold. The Z-GRAPH®F inoculating element is used when castings have chilling tendency.
Using these inoculants for in-mold melt treatment makes it possible to solve the following objectives:
- to formation of cementite in the structure of iron castings
- to improve the mechanical properties of irons
- to make the structure of irons more uniform in sections of castings having uneven wall thicknesses
- to form additional centers of crystallization
These inoculating elements have the following distinctive features:
- active dissolution in irons at low temperatures due to their chemical composition
- user-friendly as they have fixed weights and dimensions adapted to customers' gating systems
- he method used for their manufacture makes it possible to ensure the required concentrations of active elements
- consumed much more economically as compared to inoculants in crushed form used for ladle treatment
