In the international community, one of the factors determining the progress of each country is the consumption of steel and its steel products. Ferrosilicium plays a significant role in the production of steel products, which can have a huge impact on economic expansion and the country’s position in the world.
Forecasting the rapid growth of the iron and steel industry during the fifth economic development plan of the country and providing domestic demand for ferroalloys on the one hand, and the possibility of moving to export more types of ferroalloys, on the other hand, further development of this industry.
Considering steel production development plans, and especially the attraction of attention to the production of alloy steels for use in the chemical, automobile and transportation industries, ferroalloy consumption in Iran will also increase significantly in the coming years.
The major application of ferroalloys is in casting industries, thus ferroalloys play a unique role in the production of steel, castings and cast iron parts.
Therefore, increasing the production capacity of steel and cast iron in Iran will be accompanied by increased consumption of ferroalloys.
Accordingly, the amount of ferroalloy production depends on the amount of steel produced (rolling and casting) and the expansion of the casting industry, and the greater the production of steel and cast iron parts in the country, the more need for ferroalloys, especially ammonium ferrosilicon. Since steel production plays a very important role in the country's economic development, production of ferroalloys is very important for the national economy.
Product # 1
Ferroalloys are iron alloys with metals such as silicon, manganese, chromium, molybdenum, etc., which are the raw materials used in the metallurgy industry, and in particular the production of iron and steel. Among ferroalloys, ferrosilicon has the highest consumption in the industry. Ferrosilicon is produced according to the type of application in various compounds, but in general its combined ratio is 10-90% silicon and the rest is iron. At the same time, impurities such as aluminum, calcium, manganese, etc. are present. At present, ferrosilicon 75% and ferrosilicon 45% are most used in industries. The production of this plant is purely ferrosilicon 75%. In the table, the chemical characteristics of two types of ferrosilicon are shown.

Micro Silica Powder
The production process of ferrosilicon is accompanied by the production of a lot of gas and dust. This dust was treated as waste production by the 1960s and was only isolated from the exhaust gases by dust-collecting systems due to its environmental reasons and was removed from the factory after being turned into pellets. Research has shown that the resulting micro silica has received various uses and economic values, and is no longer merely a waste product, but rather as a byproduct. The chemical composition of the microsilica is shown in the table. As you can see, micro silica contains 86-96% silicon oxide. The structure of the material is amorphous (glass) and the shape of the particles is spherical. The size of the dust particles has an average dimension of about 0.15 microns and is similar to that of cigarette ash and is approximately 100 times smaller than particles of cement particles.
