ferrochrome block promoting graphite precipitation

What Are the Advantages of Ferro Chrome

The advantages of ferrochrome are outstanding, not only as deoxidizers in steelmaking, but also as good inoculants and nodulizers in casting, which can promote the morphology distribution of graphite and improve the product quality of graphite cast iron. The price of ferrochrome is lower than that of traditional ferro alloy products, so many

Technical Introduction to Inoculation of Graphitic Irons

A degree of undercooling is required during eutectic freezing to give energy for the precipitation of graphite. Low levels of undercooling promote the formation of 'A' type graphite. If undercooling falls too low, the risk for B, D and E type graphite increases. If excessive, there is a risk of carbide, and recalescance (R) tends to
