    Jan 14, 2012· It was shown that CaO-CaF 2-Na 3 AlF 6 mixture may be used effectively for dephosphorization of chromium-nickel pig iron. A 15 pct addition of cryolite is sufficient for dephosphorization of pig iron containing approximately 6 to 10 pct Cr. When the cryolite level is higher, the dephosphorizing effect becomes lower as it decreases slag basicity.
