High carbon silicon, also known as silicon carbon alloy, represents a novel alloy primarily applied in the deoxidation process during converter smelting in the iron and steel industry. This alloy consists mainly of silicon and carbon, with silicon content typically exceeding 55% and carbon content surpassing 15%. Additional components include silicon dioxide, phosphorus, and sulfur.
Production Process of High Carbon Silicon: High carbon silicon emerges as a byproduct in the production of metallic silicon. During metallic silicon production, raw materials are melted in an electric furnace. Due to uneven electrode distribution in some furnaces, the raw materials may not heat uniformly. This results in a residual amount of silica at the furnace’s bottom that doesn’t entirely react with materials like carbon. Over time, under high-temperature conditions, these accumulations form into lumps, resulting in high carbon silicon.
Material Advantages of High Carbon Silicon: As a novel composite alloy deoxidizer, high carbon silicon offers a distinct price advantage compared to other deoxidizers. It can effectively substitute traditional deoxidizers like ferrosilicon, silicon carbide, and recarburizers. High carbon silicon exhibits stable physical and chemical properties, delivering efficient deoxidation. When used in the converter steelmaking process, it rapidly reacts with oxygen in molten steel, forming steel slag on the molten steel’s surface, achieving deoxidation. Additionally, high carbon silicon provides desulfurization and recarburization effects during deoxidation, reducing steelmaking costs.

Advantages of High Carbon Silicon in Steel Production:
▶In converter steelmaking, high carbon silicon replaces ferrosilicon, silicon carbide, and recarburizers, reducing the volume of deoxidizers and stabilizing chemical components.
▶High carbon silicon accelerates the reduction process, decreases power consumption, and enhances steelmaking efficiency.
▶The decomposition and oxidation of high carbon silicon generate substantial heat, raising furnace temperature and pressure, creating essential conditions for deoxidation and desulfurization.
Advantages of High Carbon Silicon in Foundries: High carbon silicon proves advantageous for cast iron in foundries. Cast iron typically contains 2-4% carbon and 1-3% silicon, and these elements significantly influence cast iron’s microstructure. High carbon silicon, rich in carbon and silicon, serves as an effective deoxidizer, high-efficiency heating agent, and recarburizer. It helps control the input of other components and minimizes impurities.
Market Prospects for High Carbon Silicon: The steel industry has long grappled with unstable alloy compositions due to factors like uncertain steel output, key temperature variations, and slag amounts in steel production. This leads to inconsistent chemical compositions in the final steel products and low pass rates for internal control indicators. High carbon silicon offers a solution to these inherent issues. As the global economy recovers, steel industry production capacity is on the rise, driving the growing demand for high carbon silicon in steel plants.
