1. The application of silicon carbide can remove or reduce the tendency of white mouth;
2. The application of silicon carbide should avoid the occurrence of undercooled microstructure;
3. The application of silicon carbide reduces the wall thickness of cast iron castings, resulting in small differences in microstructure and hardness between thin and thick sections of castings;
4. The application of silicon carbide is conducive to the nucleation of eutectic clusters, resulting in an increase in the number of eutectic clusters;
5. The application of silicon carbide makes the morphology of graphite in cast iron 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.
