What role does 75 ferrosilicon play in steelmaking
75 ferrosilicon plays the role of deoxidizer in steelmaking.
During the steelmaking process, 75 ferrosilicon is added to molten steel and melted at high temperature to make it fully react with molten steel, effectively remove oxygen from molten steel and improve the purity and quality of steel. Compared with other steelmaking additives, 75 ferrosilicon has the advantages of high deoxidation effect, high alloying performance and environmental friendliness.
At the same time, 75 ferrosilicon can also be used as an alloying element additive to improve the performance of steel.
When to add 75 ferrosilicon during steelmaking
75 ferrosilicon is generally added at the end of converter blowing or during secondary refining of ladle during steelmaking. The specific time should be determined according to the type of steel and smelting process.
