Difference between ferrosilicon and silicomanganese

Ferrosilicon is a ferroalloy composed of iron and silicon. It is made from coke, steel scraps, quartz (or silica) as raw materials and is smelted in an electric furnace. It is widely used in steelmaking industry, foundry industry and ferroalloy industry. It is used as deoxidizer and alloying agent in steelmaking, as Sichuan inoculant and Sichuan nodulizing agent in cast iron, and as reducing agent in ferroalloy production. At present, the ferrosilicon produced in my country is mainly used for steelmaking and the production of magnesium metal. Manganese silicon is a ferroalloy with wide uses and large output. It uses manganese ore (including manganese-rich slag), coke, silica, etc. as raw materials. Its main use is steelmaking. It is mainly used as a composite deoxidizer and alloy during steelmaking. agent, and is also used as a desulfurizer to a certain extent. Ferrosilicon and manganese-silicon are ferroalloys that are widely used in the steelmaking process. The differences between them are:
First, the production raw materials are different;
Second, the uses are different: ferrosilicon is only used as a deoxidizer, while manganese silicon also has deoxidation and desulfurization effects. In addition, manganese silicon can also effectively purify molten steel;
Third, the distribution of production areas is different. Ferrosilicon production areas are mainly distributed in the northwest region, and the flow direction is mainly from northwest to southeast, such as Hebei, Liaoning, Jiangsu and other major steel-producing provinces; manganese-silicon production areas are distributed at both ends of the north and south, showing a flow from north to south. The pattern of intermediate transportation.
