Ferro Silicon Lump
Ferro silicon lumps are alloys produced by smelting in electric furnaces using coke, steel scrap, and quartz (or silica sand) as raw materials. Since silicon readily combines with oxygen to form silicon dioxide, ferro silicon is commonly used as a deoxidizer in steel making.

Product Introduction
Products Description
Ferro silicon lump is a ferrosilicon alloy supplied in lump form, which facilitates transportation, storage, and charging. It is widely used in steelmaking, casting, and alloy production, and performs well in production processes that require stable charging and uniform melting.
Compared to ferrosilicon powder, lump ferrosilicon generates less dust during transportation and charging, making it more suitable for automated charging systems and large-scale industrial production.
