What are the main benefits of adding ferrosilicon to the alloy? That is:
1. Improve the corrosion resistance of new compounds.
2. Increase the high temperature and heat resistance of the new alloy. For example, steel used in transformer cores in the production of silicon.
Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon production process:
First, silica (or sand) is mixed with coke. The reduction process is then carried out in the presence of scale, waste or other sources of iron.
The blast furnace is used for the production of ferrosilicon. However, for larger levels of silica, an electric arc furnace is used. A large portion of the global Ferro Silicon supply is produced in China, the US and India.
Ferrosilicon alloys are used in the following areas:
1. Used as a reducing agent in the production of ferroalloys.
Not only is the chemical affinity between silicon and oxygen high, but the high silicon ferrosilicon has a very low carbon content. Therefore, ferrosilicon is a commonly used reducing agent in the production of low carbon iron alloys in the iron alloy industry.
2. Used as a deoxidizer and alloying agent in the steelmaking industry.
The ferrosilicon powder can emit a large amount of heat when it is burned at a high temperature. Therefore, it is often used as a heat generating agent for steel ingot caps to improve the quality and recovery rate of steel ingots.
3. Ferrosilicon is used in the high-temperature smelting process of magnesium metal.
Magnesium in CaO.MgO was replaced. Each ton of metal magnesium produced consumes about 1.2 tons of ferrosilicon. It plays a big role in the production of magnesium metal.
4. Can be used as a coating for welding rods in the electrode manufacturing industry.
5. Ferrosilicon can be used in the chemical industry to manufacture products such as silicone.
6. Used as an inoculant and spheroidizing agent in the cast iron industry.
Cast iron is an important metal material in modern industry. It is cheaper than steel and is easy to melt and smelt. It has excellent casting properties and much better seismic resistance than steel.

7. Ferrosilicon is extensively used in the metallurgical industry for the processes of atomization, casting, melting and heavy media separation reactions.
8. The alloy is used as a basic raw material for inoculation, adjusting, suspending, mineral processing and in the melting rod industry. It is also used for deoxidization and coating in steel melting.
9. Ferrosilicon is used as a source of pure silicon in the electric industry.
10. It is used to manufacture silicon copper in the chemical industry.
11. Ferrosilicon is used in the manufacturing of semiconductors.
The steelmaking industry and the foundry industry are the largest users of ferrosilicon. They consume more than 90% of ferrosilicon.
Among the various grades of ferrosilicon, the most widely used is 75% ferrosilicon. In the steelmaking industry, about 3-5 kg of 75% ferrosilicon is consumed for every 1 t of steel produced.

Introduction to Ferrosilicon'
Ferrosilicon is an iron alloy composed of silicon and iron.
Ferrosilicon is a ferrosilicon alloy made from coke, steel scraps, and quartz (or silica) smelted in an electric furnace. It is widely used in steel industry, foundry industry and other industrial production.
Ferrosilicon commonly used grades: 65#, 75A#, 75B#, hard 75# (silicon '75%)
The commonly used content is shown in the following table (the conventional statement is that the AL content is less than 2.0):
Uses of ferrosilicon'
Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large. Therefore, ferrosilicon is a strong deoxidizer for steelmaking for precipitation and diffusion. deoxidation. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel. Therefore, it is used in the smelting of structural steel (containing 0.40-1.75% silicon), tool steel (containing SiO.30-1.8%), spring steel ( Containing SiO (40-2.8%) and transformer silicon steel (containing 2.81-4.8% silicon), ferrosilicon is also used as an alloying agent. At the same time, improving the shape of inclusions and reducing the content of gas elements in molten steel is an effective new technology for improving steel quality, reducing costs, and saving iron. It is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and has the advantages of large specificity and strong penetrating power.
Commonly used state of ferrosilicon: 10-50mm, 50-100mm, (whether there are cracks in the appearance, whether the color is faded by hand, whether the knock is crisp, the thickness of the cross section is off-white, with pores)
Commonly used packaging of ferrosilicon: bulk or ton bag packaging.
Precautions for ferrosilicon: Ferrosilicon is afraid of tides, and the natural blocks are easy to pulverize when exposed to water, and the silicon content will decrease accordingly.
