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 as an in-stream inoculant. Calcium bearing 75% Ferrosilicon is produced in state-of-the-art submerged arc.
