DESCRIPTION
Casting silicon metal involves the process of melting silicon in a furnace and then pouring the molten silicon into a mold to create a specific shape or form. Here are the general steps involved in casting silicon metal:
Raw materials: First, high-purity raw materials such as quartz, coke, and wood chips are selected and processed to create metallurgical-grade silicon.
Melting: The metallurgical-grade silicon is then melted in a furnace at a temperature of around 2,000 degrees Celsius.
Refining: The molten silicon is refined to remove any impurities that may be present.
Alloying: The molten silicon is then alloyed with other elements such as aluminum, calcium, or carbon to achieve the desired properties.
Pouring: The molten silicon is poured into a mold or cast, where it solidifies and takes on the desired shape.
Cooling: After the silicon has been poured, it is allowed to cool and solidify. Once it has cooled, the mold is removed and the finished product is ready for further processing or use.
