First of all, from the perspective of physical properties, the density of silicon-carbon alloy is smaller than that of steel, but its hardness is higher than steel, showing the characteristics of high strength, high hardness and high toughness. In addition, its electrical and thermal conductivity is also better than steel. These physical properties give silicon-carbon alloys significant advantages in manufacturing carbide cutting tools, automated machinery parts, and high-speed steel.
Application of silicon carbon alloy in steelmaking
Silicon-carbon alloys play multiple important roles in steelmaking. First of all, silicon-carbon alloy, as a composite deoxidizer, is mainly used for diffusion deoxidation when smelting ordinary carbon steel. This deoxidation method can significantly shorten the oxygen time, thereby saving energy, improving steelmaking efficiency, reducing raw material consumption, reducing environmental pollution, and improving working conditions. In addition, silicon-carbon alloy also has a carburizing effect, which is of great significance to improving the comprehensive benefits of electric furnaces.
During the steelmaking process, the silicon element in the silicon-carbon alloy reacts with oxygen to deoxidize the oxygen in the molten steel and improve the hardness and quality of the steel. This reaction also has the characteristic that molten steel does not splash, making the steelmaking process safer and more stable. At the same time, silicon-carbon alloy also has the advantage of collecting slag. It can quickly aggregate the oxides in the steelmaking process and facilitate filtration, thereby making the molten steel purer and greatly improving the density and hardness of the steel.
