1、Avoid the precipitation of carbide and diminish the white layer.

2、Increase the cutting and mechanical property.

3、increase the flowability ,and stablity of melten iron, and avoid the segregation.

4、Decrease the sectional sensitivity.

5、reinforce the capacity of heterogeneous nucleation of graphite..

6、To ductile cast iron, Silicon Carbide is a strong deoxidizer which decrease the the amount of nodulizer and increase the nodularity.

7、Reduce the costs of molten iron by reducing the rusty scrap.

8、Reduce the the damage on the furnace wall and prolong its durability..

9、Powerful deoxidation on purifying the molten iron.
