What are the production methods of ferrosilicon? What are they?

There are five main production methods of ferroalloy spot network, one is to use selected charge to produce high-purity ferrosilicon, the other is to use the method of chlorine blowing refining outside the furnace to produce high-purity and low-carbon ferrosilicon, the third is to use the method of top-blowing oxygen outside the furnace to produce high-purity and low-alumina ferrosilicon, the fourth is to use the method of hot slag washing to produce high-purity and low-carbon ferrosilicon, and the fifth is to use the method of selected charge to produce low-alumina and low-carbon ferrosilicon. The production of high-purity ferrosilicon by the method of selecting charge materials is mainly through the smelting and production of selected quartz stone, petroleum coke, wood block, charcoal and silicon steel sheet raw materials, so as to achieve the purpose of reducing the content of impurity elements in the product. Due to the large fluctuation of raw material quality, it is inevitable to bring in a part of impurities in the smelting production process, so that the reduction rate of impurity content in the product is limited, the product quality is not high, the yield is low, and the production furnace condition is difficult to maintain, the furnace mouth operation is difficult, the production cost and energy consumption of the product are larger, and the economic indicators are poor.

The furnace method has a good effect on removing calcium and aluminum, but there is more exhaust gas, and there are often leaks and chlorinated graphite pipes broken and refining is suspended in production, which seriously pollutes the environment, endangers the health of workers, and corrodes the production equipment.

Ferrosilicon is a ferroalloy composed of iron and silicon.

Ferrosilicon is also called silicon [ xī ] iron. It is an iron-silicon alloy made of coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. It is widely used in the steel industry, foundry industry and other industrial production.

Ferroalloy composed of iron and silicon (silicon reduced at a high temperature of 1500-1800 degrees Celsius with silica, steel, and coke as raw materials is melted into molten iron to form ferrosilicon alloy). It is an important alloy variety in the smelting industry.

Smelting: Ferrosilicon is made by smelting with an electric furnace using coke, steel scraps, quartz (or silica) as raw materials. Traditionally, ferrosilicon is made by reducing silicon from silica containing SiO2. Most of the smelting of ferrosilicon uses metallurgical coke as a reducing agent, and steel scraps are the regulator of ferrosilicon.

Uses of Silicon:

High-purity monocrystalline silicon is an important semiconductor material. Trace amounts of group IIIA elements are incorporated into monocrystalline silicon to form p-type silicon semiconductors; A small amount of group VA elements is incorporated to form n-type and p-type semiconductors combined, which can be made into solar cells, which convert radiant energy into electrical energy. It is a promising material in the development of energy sources.

Cermet, an important material for astronautics. Ceramics and metals are mixed and sintered to make cermet composites, which are resistant to high temperatures, rich in toughness, and can be cut, which not only inherits the respective advantages of metals and ceramics, but also makes up for the congenital defects of both.

The first space shuttle can be applied to the manufacture of military **"USS Columbia"It can withstand the high temperature caused by the friction when traveling through the dense atmosphere at high speed, all thanks to its shell made of 31,000 silicon tiles.

Optical fiber communication, the latest modern means of communication. Pure silica is used to draw high-transparency glass fibers, and the laser is transmitted forward with countless total reflections in the path of the glass fibers, replacing bulky cables.

Optical fiber communication capacity is high, a hair as fine as a glass fiber, can transmit 256 channels at the same time**, it is also not subject to electrical and magnetic interference, not afraid of eavesdropping, with a high degree of confidentiality. Fiber optic communication will revolutionize human life in the 21st century.

Excellent performance of silicon organic compounds. Silicone plastics, for example, are excellent waterproof coating materials. Spraying silicone on the walls of an underground railroad can solve the problem of water seepage once and for all.

On the surface of ancient cultural relics and sculptures, a thin layer of silicone plastic can prevent the growth of moss and resist wind, rain and weathering. The Monument to the People's Heroes in Tiananmen Square is treated with silicone plastic, so it is always white and fresh.

Organosilicon compounds refer to compounds that contain Si-O bonds and at least one organic group is directly linked to silicon atoms, and those compounds that connect organic groups to silicon atoms through oxygen, sulfur, nitrogen, etc. are also commonly regarded as organosilicon compounds.

Among them, polysiloxane composed of silicon-oxygen bond (-si-0-si-) as the skeleton is the most numerous, deepest-studied and most widely used class of organosilicon compounds, accounting for more than 90% of the total dosage.

Ferrosilicon is a ferroalloy composed of iron and silicon.

Ferrosilicon is an iron-silicon alloy made by smelting coke, steel scraps, quartz (or silica) as raw materials and using an electric furnace. Because silicon and oxygen are easy to synthesize silica, ferrosilicon is often used as a deoxidizer in steelmaking, and because SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.

At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon is often used as a reducing agent in ferroalloy production and chemical industry.

Ferrosilicon is an indispensable deoxidizer in the steelmaking industry, and in torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.

Ferrosilicon contains a small amount of phosphorus metal compounds, such as calcium phosphide, etc., when transported by vehicles and ships or stored in warehouses, if moisture, phosphine will be released, causing poisoning in or around the warehouse.

Ferrosilicon is often used as a deoxidizer in steelmaking, and because SiO2 releases a lot of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. Ferrosilicon can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.

Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, increase the permeability of the steel, and reduce the hysteresis loss of the transformer steel.

High-silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as a reducing agent for the production of low-carbon ferroalloys from jujubes.
