Calcium-containing ferrosilicon—FeSi(Ca)—does give much higher calcium yield than calcium disilicide during calcium treatment of steel under laboratory conditions, in line with industrial observations. Upon calcium treatment of both aluminum-killed and silicomanganese-killed steel, a new population of small calcium-rich inclusions forms. The results indicate that pre-existing (deoxidation) inclusions dissolve into the liquid steel after calcium addition, rather than directly reacting with the added calcium.
