1. The natural block of ferrosilicon serves as a deoxidizer in the steel smelting process, effectively reducing the oxygen content in the molten steel and improving the purity and quality of the steel. As an alloying element, by adjusting the proportion of silicon iron, the chemical composition and physical properties of steel can be changed, such as improving strength, hardness, and corrosion resistance. As an inoculant in the casting industry, it improves the microstructure of cast iron and enhances its mechanical and processability properties. In the process of non-ferrous metal smelting, it is used as a reducing agent or alloy additive to adjust the chemical composition and physical properties of non-ferrous metals. Used for preparing composite materials such as silicon aluminum alloys and silicon titanium alloys, it has a wide range of applications in aerospace, automotive manufacturing, and other fields. In the chemical industry, it is used to prepare silicides such as potassium silicate and sodium silicate, which have important applications in industries such as glass, ceramics, and coatings.

2: Due to its stable chemical composition, ferrosilicon standard blocks are more suitable for situations where material composition needs to be controlled, such as the production of stainless steel, alloy steel, and high-temperature alloys. It exhibits good stability at high temperatures and is therefore also used in the production of composite materials such as silicon aluminum alloys and silicon titanium alloys. It is an important raw material for manufacturing critical components such as wafers in the semiconductor industry. In the chemical production process, it can also be used as a deoxidizer to remove oxygen from the reaction system. There are significant differences between natural blocks and standard blocks of ferrosilicon in terms of composition, shape, stability, and application scenarios. Understanding these differences can help in selecting suitable silicon iron materials based on specific needs.
