Ferrosilicon is an iron alloy composed of iron and silicon, now ferrosilicon has a wide range of applications, ferrosilicon can also be used as an alloying element adding agent, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in the production of ferroalloys and the chemical industry, often used as a reducing agent. However, many people only understand the use of ferrosilicon, and do not understand the smelting of ferrosilicon and smelting problems will be found.
In order to be able to deepen your understanding of ferrosilicon, ferrosilicon suppliers simply analyse the reasons for the low carbon content in ferrosilicon.
The reason why the smelted ferrosilicon has low carbon content is mainly due to the fact that when smelting ferrosilicon, the manufacturer will use coke as a reducing agent, make it easier to increase the carbon of the self-baking electrode, use coke bricks to build the iron outlet and the flow of iron troughs, sometimes use graphite powder to coat the ingot moulds, and use the charcoal sample spoon to take the liquid sample and so on. In short, smelting ferrosilicon from the furnace reaction until the iron, pouring process, and carbon contact opportunities are obviously many. Ferrosilicon silicon content in the higher, the lower its carbon content.
Ferrosilicon in the silicon content of about more than 30 ﹪, ferrosilicon in the vast majority of carbon is to silicon carbide (SiC) state. Silicon carbide is easily oxidised by silicon dioxide or silicon monoxide in the crucible and is reduced. Silicon carbide in ferrosilicon, especially when the temperature is low, its solubility is very small, easy to precipitate and float. Therefore, the silicon carbide in ferrosilicon is very low, so the carbon content of ferrosilicon is very low.
