Foundry Inoculants Suppliers

Inoculants are added in liquid cast iron in order to provide the best and consistent characteristics in the final casting. They are used to control matrix structure and avoid casting defects. Inoculants can be found under several grain size distributions to satisfy the location of the inoculant addition within the foundry process. Those locations of inoculant addition are known as in furnace, in ladle, in stream or in mould.

Inoculants are ferrosilicon based alloys. Fortune products differ from each other, assisted by one of our technical expert, will make a selection depending of the chosen application and the foundry process in question. All elements which are barium, calcium, aluminum, and rare earth can be added in the exact amount into the base liquid iron in order to provoke and certify the final casting matrix structure.

Inoculants are available as per casting requirements and micro structural requirements as Si base, Ba base, Sr base

Sizes Offered : 0.3mm-0.9mm, 1mm-3mm, 3mm-6mm

Barium based inoculant, is known to improve graphite nucleation and reduce fading. Suitable for most applications, and especially for applications involving long holding periods, the combination of Calcium and Barium give most efficient chill control and minimum amounts of slag

The addition of inoculants in liquid cast iron (grey and ductile irons) allows us to:

• Improve the homogeneity of the cast iron structure
• Eliminate the formation of carbides into thin parts or salient angles
• Direct the solidification towards the stable diagram, with graphite precipitation
• Refine the structure (higher cells count, finer grains in the microstructure)
• Improve mechanical properties
• Better separate slag and metal
• Decrease the tendency to dross formation
• Decrease the tendency to micro-shrinkage
• Decrease risk of gas formation
