The Description Of High Carbon Silicon

Jan 09, 2026

Silicon carbon alloy is a novel alloy primarily used in the deoxidation and alloying process of converter smelting, also known as silicon carbon alloy or high carbon silicon. Its main characteristics and applications are as follows:

 

Main Components: The main components of silicon carbon alloy are silicon and carbon, with silicon content typically exceeding 55% and carbon content exceeding 15%.

 

Physical Properties: It possesses excellent heat resistance and corrosion resistance, resisting oxidation and corrosion, thus extending the material's service life. Simultaneously, silicon carbon alloy also exhibits good electrical and thermal conductivity, with electrical conductivity superior to ordinary cast iron and steel, and relatively good thermal conductivity as well.

 

Metallurgical Applications: Silicon carbon alloy can replace traditional metallurgical materials such as ferrosilicon, silicon carbide, and carburizing agents, reducing the amount of alloy added and lowering steelmaking costs. During the steelmaking process, silicon carbon alloy can improve the quality of molten steel and enhance its properties, such as increasing hardness and weight. Furthermore, silicon carbon alloy can increase furnace temperature, accelerate the conversion rate of ferroalloys, and speed up the reaction rate between molten steel and elements.

 

Other applications: Silicon carbon alloys also possess certain strength and hardness, making them suitable for manufacturing wear-resistant materials and friction braking materials. Furthermore, due to their excellent electrical and thermal conductivity, silicon carbon alloys can be used to manufacture electric furnace electrodes, electric furnace liners, and other electric furnace refractory materials, as well as radiators and thermal conductive materials.

 

In summary, silicon carbon alloys are a high-performance, widely applicable new type of alloy, playing a vital role in metallurgy and other industrial fields.
