Ferrosilicon Overview
Ferrosilicon alloy is an iron alloy product characterized by the presence of abundant Si, and trace elements such as Fe, Mn, Al, C, P, and S. The raw materials for ferrosilicon alloys mainly include quartz stone, charcoal, steel shavings, pig iron, etc. The raw materials are heated in an electric furnace to melt them, and carbon-reducing agents such as charcoal are used to reduce the SiO₂ in the quartz stone and precipitate out the Si, thus producing a chemical reaction with the elements in other raw materials, after cooling, ferrosilicon alloys of different contents are produced.

Ferrosilicon 75
Ferrosilicon 75 is a kind of Si≥75% ferrosilicon, which is a high-purity ferroalloy product, and it is widely used in steel making and casting. Ferrosilicon 75 is mainly available in particle sizes of 10mm~50mm,50mm~100mm,100~150mm, etc. It is suitable for a variety of electric furnaces. Quartz stone, charcoal (reducing agent), and iron scrap are the main raw materials of ferrosilicon 75. To produce high-purity ferrosilicon 75, the raw materials must be strictly screened, quartz stone requires low ash and few impurities, and the choice of high-quality charcoal can better reduce the silicon in silica in silica, thus producing ferrosilicon 75 with the high silicon content.

Ferrosilicon 72
Ferrosilicon 72 is a kind of ferrosilicon with more than 72% silicon element, 72 is to better differentiate its internal silicon element content. Ferrosilicon 72 has higher purity and less impurity content, which can effectively enhance the process and improve product quality in the process of steel making and casting. Different products and processes have different requirements for ferrosilicon 72 in terms of particle size and physicochemical indexes. In order to produce ferrosilicon 72 that can be used in a variety of scenarios, manufacturers crush the freshly smelted ferrosilicon 72 and filter it through a screen to make its particle size more uniform. The advantage of this is that on the one hand, it is easier to pack, transport and store, and on the other hand it is more convenient to use, but of course, many manufacturers provide customized services to meet the needs of different users.

Ferrosilicon 65
Ferrosilicon 65 consists of Si, Fe, Ca, C, Al, S, P, etc element, with Si ≥ 65%, Fe ≤ 2.5, and the rest trace elements. Ferrosilicon 65 is currently the most widely used additive in steelmaking and casting, mainly due to its high elemental silicon content. Quartz stone, carbon, iron scrap and steel scrap are the main raw materials used in the production of ferrosilicon 65. The raw materials are heated by an electric furnace, which melts the raw materials, precipitates silicon from the quartz stone using a carbon reducing agent, and reacts chemically with other elements to produce the primary ferrosilicon 65.

About The Ferrosilicon Production Process
In 1810, J.J.Berzelius was the first to smelt ferrosilicon by putting quartzite, steel scrap, and coke into a calciner, thus smelting low-grade ferrosilicon with a silicon content of 2.2% to 9.3%.
In 1875, A. Pourcel successfully smelted ferrosilicon with a silicon content of 10% to 18% using a blast furnace.
In 1899, Du Cholmol smelted ferrosilicon with 25% to 50% silicon content using a mineral-heated furnace at the Holcim Rock plant in the United States.
In 1903, Kadar improved on DiCharmel's method of producing ferrosilicon and successfully smelted ferrosilicon with 75% silicon content using an electric furnace. Kadar's method of smelting ferrosilicon using electric furnaces continues to be used today, and with continuous improvements, ferrosilicon manufacturers can now smelt various grades of ferrosilicon with lower impurities and higher purity of ferrosilicon.
