‌Remove or reduce the tendency of white spots, avoid the occurrence of supercooling structures, reduce the wall thickness of cast iron parts to make the difference in microstructure of castings small, facilitate the nucleation of eutectic clusters, and improve the morphology of graphite Thereby improving the mechanical properties of cast iron, reducing production costs and improving production efficiency‌‌.

1. The application of silicon carbide can significantly remove or reduce the whitening tendency of castings and improve the quality of castings.‌

2. It can avoid the occurrence of supercooling structure during the casting process and ensure the microstructure of the casting is uniform.‌

3. Silicon carbide can also reduce the wall thickness of cast iron parts, reduce the difference in microstructure and hardness between thin and thick sections of the casting, thereby improving the overall performance of the casting.‌

4. It is conducive to the nucleation of eutectic clusters, increases the number of eutectic clusters, and further improves the microstructure and mechanical properties of castings.‌

5. The application of silicon carbide can also change the form of graphite in cast iron into fine and evenly distributed A-type graphite. This graphite form helps to improve the mechanical properties of cast iron.‌

6. Finally, the use of silicon carbide can also reduce production costs, improve production efficiency, and bring economic benefits to the foundry industry.
