What is silicon carbide:

Silicon carbide deoxidizer is a new type of composite deoxidizer with good performance, which can replace the expensive traditional deoxidizer ferrosilicon powder and alloy powder. It is suitable for deoxidization during smelting of general steel, alloy steel and special steel. It has the characteristics of rapid deoxidization, early slag formation, strong reducing atmosphere, rich foam, etc. It can also improve the recovery rate of elements, and also has the role of carburization, replacing some of the carburizer, reducing the cost of steelmaking. Using silicon carbide as a deoxidizer in steelmaking can stabilize the quality of molten steel, refine grain size, and clean harmful impurities in the steel. After use, the casting temperature of the steel is high, the quality of the cast billet is good, and the unit cost is low.

What are the characteristics of silicon carbide

1. Enhance the nucleation ability of graphite, reduce the undercooling of molten iron, and decrease the tendency of white casting in castings;

2. Good deoxidation effect, purifying molten iron;

3. Extend the service life of furnace lining;

4. Reduce undercooled graphite in gray cast iron and promote the formation of A-type graphite;

5. Adding graphite balls in ductile iron production can increase the number of graphite balls, improve the spheroidization rate, make the graphite balls more round and smaller, and reduce the amount of spheroidizing agent added;

6. Replacing ferrosilicon smelting can reduce aluminum content and minimize subcutaneous porosity.

What is the role of silicon carbide in casting

1. The application of silicon carbide can remove or reduce the tendency of white casting;

2. The application of silicon carbide should avoid the occurrence of undercooled structure;

3. The application of silicon carbide reduces the wall thickness of cast iron parts, making the difference in microstructure and hardness between thin and thick sections of castings small;

4. The application of silicon carbide is beneficial for the nucleation of eutectic clusters, increasing the number of eutectic clusters;

5. The application of silicon carbide results in the morphology of graphite in cast iron being mainly small and uniformly distributed A-type graphite, thereby improving the mechanical properties of cast iron;

6. Silicon carbide can reduce production costs and improve production efficiency.
