What's The Performance Of High Carbon Silicon
Jan 12, 2026
Performance Revolution: A Three-in-One Industrial Tool
(I) A "Dual-Effect Engine" in Smelting
1. Composite Deoxidation
Silicon preferentially combines with oxygen in molten steel to form low-melting-point SiO₂ that floats upwards, reducing the oxygen content per ton of steel to below 15 ppm. A plant in Hebei province replaced the traditional ferrosilicon + recarburizer solution, resulting in a cost reduction of 140 yuan/ton.
2. Precise Carbon Addition
Carbon elements are dispersed in the form of nano-silicon carbide, avoiding the uneven composition caused by the floating of traditional recarburizers. A steel mill producing automotive steel reduced carbon deviation control from ±0.05% to ±0.02%.
3. Exothermic Heating
Silicon oxidation releases heat, raising the temperature of molten steel by 25-30℃. Short-process steel mills can use this to reduce arc heating time, saving 45 kWh of electricity per ton of steel.
(II) A "Defect Buster" for Foundries
Anti-shrinkage expert: Micro-expansion during solidification compensates for shrinkage, reducing the scrap rate of a Shandong wheel hub factory from 18% to 4%;
Graphitization promoter: Promotes the precipitation of fine flake graphite, increasing the cutting efficiency of machine tool guideway castings by 55%;
Impurity purification: Silicon-carbon reaction adsorbs aluminum and titanium impurities in steel, reducing the number of inclusions in a nuclear power pump body by 70%.
(III) A "Space Storage Springboard" for New Energy
CATL's mass production of silicon-carbon anodes in 2025:
Nano-silicon framework: Acid etching of alloys forms a porous structure, achieving a specific capacity exceeding 2200mAh/g;
Conductive network: Residual carbon skeleton constructs high-speed electron channels, achieving a cycle life of 1200 cycles;
Cost reduced to $15/kg, driving electric vehicle range to exceed 1000 kilometers.
