Calcium Bearing 75%
Ferrosilicon
For Gray and Ductile
Iron Inoculation
In Gray Iron: Calcium-bearing
75% Ferrosilicon acts as an inoculant, serving to reduce chill on edges
and in thin sectioned castings. The inoculation effect, created principally
by the controlled calcium content, results in improved graphite shape
and increased physical and mechanical properties. The addition of an
inoculant also reduces section sensitivity. Typical addition levels
to gray iron are 2-6 pounds/ton of metal.
In Ductile Iron: Calcium-bearing
75% Ferrosilicon has been the favored inoculant of the ductile iron
industry for many years. Addition rates are normally much higher in
ductile iron than in gray iron, varying from 7-22 pounds/ton of metal.
Late Inoculation: The
20M x 80M size is specially prepared to be suitable for sprue inoculation,
or for use in mechanized stream injection apparatus.
