The main raw materials for ferroalloys include manganese ore, silica, coke and steel scraps. Specifically, the main raw materials for manganese-silicon alloys are manganese ore, silica and coke, while the main raw materials for ferrosilicon alloys are silica, coke and steel scraps.
Raw materials for manganese-silicon alloys
Manganese ore: Manganese ore is one of the main raw materials for manganese-silicon alloys, providing manganese.
Silica: Silica provides silicon and is an important component of manganese-silicon alloys.
Coke: Coke is used as a reducing agent in the production process to help reduce manganese and silicon oxides.
Raw materials for ferrosilicon alloys
Silica: Provides silicon and is the basic raw material for ferrosilicon alloys.
Coke: Also acts as a reducing agent to help reduce silicon oxides.
Steel scraps: The addition of steel scraps can further adjust the composition and performance of the product.
