Advantages of High Carbon Silicon
As a new type of composite alloy deoxidizer, high carbon silicon has an absolute price advantage compared to other types of deoxidizers and can replace traditional deoxidizers such as ferrosilicon powder, calcium carbide, carbon powder, alloy powder, etc. High carbon silicon has stable physical and chemical properties and a good deoxidation effect. Used in the converter steelmaking process, it can quickly react with the oxygen in the molten steel to form steel slag floating on the surface of the molten steel, thereby achieving the purpose of deoxidation. High carbon silicon has certain desulfurization and recarburization effects while deoxidizing, which can replace part of the recarburizer, thereby greatly reducing the cost of steelmaking.

The silicon element (Si) in high carbon ferrosilicon has both deoxidation and desulfurization capabilities, while carbon (C) contributes to carburization and deoxidation. Including these elements in the deoxidizer aims to enhance steel quality. High carbon ferrosilicon leverages the beneficial properties of silicon and carbon in the deoxidation process, forming a composite deoxidizer with strong affinity for silicon, carbon, and oxygen, resulting in significant deoxidation power.
As high carbon ferrosilicon primarily consists of [Si] and [C], its deoxidation products easily float to the surface and can be removed without contaminating the molten steel. This reduces the risk of inclusions like Al₂O₃ and offers some ability to remove sulfur ([S]) and phosphorus ([P]).
Application of High Carbon Silicon
Used as a deoxidizer in the steelmaking industry. High-carbon silicon can replace ferrosilicon, silicon carbide and recarburizer, but also reduce the amount of deoxidizer. It is used in converter smelting deoxidation alloying process, and its effect is stable. The chemical composition of steel, mechanical properties and internal control quality are better than the traditional process. Used as inoculant and spheroidizing agent in the cast iron industry. Used as reductant for low carbon iron alloys.
Production Process of High Carbon Silicon
High carbon silicon is a subsidiary product produced in the production of metallic silicon. In the production process of metallic silicon, the raw materials are smelted in an electric furnace. Due to the uneven distribution of electrodes in some furnaces, uneven heating of the raw materials may occur. A small amount of silica at the bottom of the furnace did not completely react with raw materials such as carbon. In a high-temperature environment, after a long time accumulation, a lump-like product is formed at the bottom of the furnace. These products are high carbon silicon.
