Differences between Fast-melting silicon and metallurgical silicon:
Metallurgical silicon undergoes high-temperature diffusion melting in molten aluminum liquid to achieve alloying. Because the specific gravity of silicon is lighter than that of aluminium, if this method of alloying is not handled properly, the Metallurgical silicon blocks will float up, causing local oxidation and making it difficult to melt. This can easily lead to oxide inclusions and increase the tendency to absorb gas during the melting process.
The difference between fast-melting silicon and crystalline silicon:
Crystalline silicon undergoes high-temperature diffusion melting in molten aluminum liquid to achieve alloying. Because the specific gravity of silicon is lighter than that of aluminium, if this method of alloying is not handled pro- perly, the crystalline silicon blocks will float up, causing local oxidation and making it difficult to melt. This can easily lead to oxide inclusions and increase the tendency to absorb gas during the melting process.
The difference between fast-melting silicon and silicon flux:
Due to the presence of additives and other substances in the silicon flux, it is inevitable that the aluminum liquid will have a tendency to absorb air. The fast-melting silicon is only a flux, avoiding the generation of gas absorption.
Fast-melting silicon is made from crystalline silicon blocks through special processing techniques and is used to adjust the silicon content in aluminum alloys, replacing the original silicon fluxs and aluminum-silicon master alloys.
