High Purity Ferro Silicon 75 10-100mm

Ferrosilicon alloy production technology is generally divided into two methods: the external furnace method and the internal furnace method.

1. Secondary furnace method
The secondary furnace method refers to the method of producing a gaseous compound (e.g., silicon trichloride SiCl4) from calcium carbide or silica and then reducing it to a ferrosilicon alloy using a reducing agent. This method has a proven technology and high efficiency, but the technological process is complex.

2. Furnace method
The furnace method is a method of mixing siliceous raw materials (such as ferrosilicon, silicon slag, wollastonite, etc.) with iron-containing materials and placing them in an electric furnace or blast furnace to melt and reduce them into a ferrosilicon alloy. This method is characterized by the simplicity of the process and a wide range of applications, but it has low thermal efficiency and a slow chemical reaction rate.

Ferrosilicon alloy is not only widely used in the steel and foundry industries, but also contributes to the research, development and production of many new products. For example, Si-Fe-Mn-Cr-Mo alloy, silicon fiber, silica gel and other products are widely used in many fields, such as chemical, electronics, communications, and construction.
