The difference and connection between ferrosilicon and manganese silicon

Both ferrosilicon and manganese silicon are added raw materials in steelmaking. They are mainly used to remove oxygen in steel and increase the toughness and strength of steel. They are indispensable substances in steelmaking. So what is the difference and connection between ferrosilicon and manganese silicon?

Ferrosilicon is a ferroalloy composed of iron and silicon, which is made by smelting in an electric furnace with coke, steel shavings, quartz (or silica) as raw materials. It is widely used in steelmaking industry, foundry industry and ferroalloy industry. It is used as deoxidizer and alloying agent in steelmaking, as inoculant and nodulizer in cast iron, and as reducing agent in ferroalloy production. At present, domestic ferrosilicon is mainly used for steelmaking and magnesium metal production.

Manganese silicon is a ferroalloy with wide application and large output. It uses manganese ore (including manganese-rich slag), coke, silica, etc. as raw materials. The main use is steelmaking. It is mainly used as a composite deoxidizer and alloy in steelmaking In addition, it is also used as a desulfurization agent to a certain extent.

Ferro-silicon and manganese-silicon are the most widely used ferroalloys in the steelmaking process. The biggest difference between them is that the raw materials for production are different. Second, the usage is different. Ferrosilicon is only used as a deoxidizer, while silicomanganese has the effect of deoxidation and desulfurization at the same time. In addition, silicomanganese can also effectively purify molten steel.
